Abstract: Savory belongs to the family Lamiaceae and genus Satureja. Among the 16 species of savory in Iran, 9 are endemic to Iran. In this study, we evaluated the adaptation of different savory accessions (Satureja spp.) in the climatic condition of Kurdistan province. For this purpose, we studied 37 accessions belonging to 10 species of Satureja in an experiment with a randomized complete block design in three replications at the Grize Station in Sanandaj during 2009-2013. Savory species include S.sahendica Bornm, S. avromanica Maroofi, S. bachtiarica Bunge, S. spicigera (C. Koch) Boiss, S. mutica Fisch, S. macrantha CAMey, S. atropatana Bunge, S. rechingeriJamzad ,S. khuzistanica Jamzad, S.isophylla Rech. First, we collected the seeds of 37 populations from the Satureja spp. from different regions of Iran as a part of a large project executed by experts in the Iranian Research Institute of Forests and Rangelands. Then we planted the seeds using transplanting trays and finally at the stage of 8-10 leaves, the healthy plants were selected to be cultivated in special pots. Based on the results of variance analysis there was a significant difference between species and accessions at the level of (p≤0.01) in terms of essential oil yield percentage, essential oil yield per hectare (based on the dry weight of flower and leaf per hectare), total phenolic compounds of essential oil, plant’s fresh weight yield per hectare and plant’s dry weight yield per hectare, dry weight of leaf and flower yield per hectare, canopy area, the mean of the branch’s height and establishment percentage. Also, the effect of year on essential oil yield was significant.

The cultivation of medicinal plants such as the Lamiaceae family increasing throughout the world Significantly. Savory considers as an important species in this family which it’s important is due to carvacrol and thymol in essential oil. In order to investigate the effect of planting density and soil fertility on the physiological traits and antioxidant enzymes activity of savory under rainfed conditions, an experiment in the form of split plots with two factors, fertilizer as the main factor at three levels (control, 30 tons/ha cow manure and 10 tons/ha straw enriched with ammonium sulfate) and the sub-factor, plant density at three levels (2.67, 4 and 8 plants/m2) in the form of a complete block design A random experiment was conducted at Hamand Absard research station (Damavand) in 2017-18 and 2018-19. The analysis of variance showed a significant effect of planting density and organic fertilizers on the physiological traits of savory. The highest RWC (%87.67) and the lowest ELI (%47.19) were observed in the cow manure treatment with 30 tons/ha at a density of 2.67 plant/m2. As the density increased, total chlorophyll and RWC decreased and ELI and MDA and proline increased. Cow manure and straw increased total chlorophyll, proline and RWC and decreased ELI and MDA. The highest activity of CAT, peroxidase and SOD enzyme was obtained in the control treatment and 8 plant/m2 and the lowest in organic fertilizer treatment, 2.67 plant/m2. Increasing the activity of these enzymes to neutralize the reactive oxygen species produced due to water stress is known as a resistance mechanism in plants. Based on the results of this research, it can be said that savory has the ability to grow in rain-fed conditions and has the necessary potential to increase the antioxidant capacity in rainfed conditions.

Bachground and objective: Deficiency or excess of any growth factor leads to morphological, anatomical, physiological, and growth disorders in plants. Drought stress means a lack of water in the plant. This situation occurs when the amount of transpiration exceeds the amount of water absorption. Low irrigation (watering less than the optimal water requirement of the plant) is a strategy to save water, but it affects the plant at a particular stage of growth or the entire season. Biofertilizers develop the root system, changing host plant water relations and plant metabolism. They also activate the defense system, improving access to minerals and tolerance to drought in the host plant, making it environmentally friendly and natural. To manage the prevailing water crisis, one should look for solutions such as reducing water consumption and stopping irrigation at all stages of growth. This is without harming the plant's final performance. In addition, due to the importance of medicinal plants and increasing their biomass, biological fertilizers and the adjustment of drought stress effects have a special place. This experiment was carried out to investigate the effectiveness of Satureja bachtiarica Bunge. against dehydration at different stages of growth. It also investigated the consumption of mycorrhizal fungi and growth-stimulating bacteria to manage plant production with high quality and quantity.Methodology: The experiment was carried out in the form of split plots in the form of a randomized complete block design in three replications in the research farm of Islamic Azad University, Tabriz branch, in 2018. The main and sub-factors were included in 4 water stress (I1: without stress, I2: cut irrigation in stem elongation stage, I3: cut irrigation at the budding stage and I4: cut irrigation at 50% flowering stage) and 5 biofertilizer levels (b1: without inoculation, b2: inoculation with Funneliformis mosseae, b3: inoculation with Rhizophagus irregularis, b4: Funneliformis mosseae + Rhizophagus irregularis and b5: Azosprillium+Pseudomonas+Azetobacter), respectively. The harvest was in full flowering stage.Results: The comparison of the average of irrigation interruptions showed that the most number of leaves, stem diameter, canopy extent, root weight, leaf yield, flowering stem yield, and flowering branch yield belonged to the irrigation interruption at the 50% flowering stage. Inoculation with Funneliformis mosseae mycorrhizal fungus achieved the highest leaf yield (912.06 kg/ha), flowering stem yield (1071.25 kg/ha) and flowering branch yield (1983.32 kg/ha) in inoculation with Azosprillium + Pseudomonas + Azotobacter was observed. The highest percentage of essential oil was found in inoculation with Funneliformis mosseae with an average of 1.76%. The maximum average yield of essential oil at 30.50 kg/ha was observed in the inoculation treatment with Azosprillium + Pseudomonas + Azotobacter. The results of the comparison of the average of the interaction effect showed that the maximum height of the plant and the number of inflorescences with an average of 61.72 cm and 30.46 per plant were found in the interaction effect of the treatment of interruption of irrigation at the stemming stage and inoculation of Rhizophagus irregularis + Funneliformis mosseae, which is about 31 and 39 The percentage increased compared to their lowest value. Stopping irrigation in the budding stage ×Funneliformis mosseae had the highest percentage of essential oil with an average of 2.33%. Stopping irrigation in the stemming stage ×Rhizophagus irregularis had the lowest essential oil percentage. The highest leaf yield (1212.83 kg/ha), flowering stem yield (1494.75 kg/ha), flowering branch yield (2707.58 kg/ha) and essential oil yield (44.39 kg/ha) in the interaction effect of cutting × Azosprillium + Pseudomonas + Azotobacter irrigation was observed at the 50% flowering stage, which increased by 70, 82, 81 and 87% compared to the lowest ones.Conclusion: The correct management of soil fertility, improvement, and maintenance of soil fertility in modern agricultural systems will provide the nutrients needed by the plant and thus enhance the yield. Therefore, in recent years, many studies have been conducted on biological fertilizers. Mycorrhizal fungi are essential factors in the stable plant-soil system, which coexists with more than 85% of plants. Drought stress is one of the most influential environmental factors in plant growth and causes morphological, physiological, and metabolic changes. In addition, biofertilizers increase plant access to nutrients and produce and direct hormones involved in the growth of the root environment. They also increase stress tolerance and enhance yield. Considering the arid and semi-arid conditions of the country and the increase in demand for medicinal plants and Satureja bachtiarica spices, it is recommended to stop irrigation at the 50% flowering stage and use Azotobacter, Azospirillium, and Pseudomonas biofertilizers to obtain the maximum yield of leaves, flowering branches, and essential oil.

Background and objectives: Awareness of changes in medicinal plant yield quantity and quality over time is one of the most important goals in agricultural management. Satureja mutica is one of the valuable medicinal species growing in Iran. This study was conducted to evaluate the effects of different planting beds on changes in vegetative characteristics and essential oil components over the years of growth in S. mutica under rainfed conditions.Methodology: The experiment was conducted in the form of split plots in a randomized complete block design for three years (2018-2020) in the rainy conditions of Feridounshahr city, Isfahan province. Planting beds as the main plot included cow manure (30 tons per hectare), wheat straw (10 tons per hectare), and control (without cow manure and wheat straw). After the preparation of the field, the seedlings were planted at the bottom of the wells created at a distance of 50 x 50 cm from each other. During the growing season and at the time of 50% flowering, the studied traits including total plant dry weight, leaf and stem dry weight, plant height, crown diameter per plant, canopy area per plant, and in each square meter of land and the number of stems per plant were measured. For essential oil extraction, the flowering branches of the plants were harvested at the full flowering stage. After drying in the shade, the essential oil was extracted by the water distillation method. After determining the yield of essential oils based on the dry weight of the plant, the essential oils were analyzed and identified by gas chromatography, and gas chromatography was connected to a mass spectrometer in the phytochemistry laboratory of the Research Institute of Forests and Rangelands. Considering that the plant is several years old and measurements are carried out every year on fixed plots, the design analysis was done on divided plots at the time of implementation. The SAS computer program was used to perform statistical calculations, and the LSD test was applied to compare the means. For essential oil extraction, the flowering branch of the plant was harvested at the full flowering stage. After drying in the shade, the essential oil was extracted by the water distillation method. After determining the yield of essential oils based on the dry weight of the plant, the essential oils were analyzed and identified by gas chromatography, and gas chromatography was connected to a mass spectrometer in the phytochemistry laboratory of the Research Institute of Forests and Pastures. The SAS computer program was used to perform statistical calculations, and the LSD test was used to compare the means.Results: The variance analysis of the data showed that the effects of bed, year, and their interaction effects on the measured traits were significant in many cases. Results showed that the highest values of plant height, crown diameter, canopy area, and number of stems per plant in the first year were seen in manure treatment. In the last year, they were in control. The highest rates of total dry weight, leaf dry weight, essential oil yield, and essential oil percentage were observed in control in the last year. These rates were 1427, 891, 42 kg ha-1, and 4.67%, respectively. The main essential oil components are thymol, carvacrol, p-cymene, and gamma-terpinene. These essential oil components are affected by the planting bed and the growth year. So in the case of p-cymene, the highest amount obtained in the first year was in the straw treatment. The highest amounts of gamma-terpinene were observed in all three planting bed treatments in the last year of growth. S. mutica had significant amounts of thymol, and the trend of changes among planting bed treatments and during growing years was very small. The highest amounts of carvacrol were observed in straw treatment and animal manure in the second year of growth. The results of the correlation coefficients showed that the most vital traits affecting essential oil yield were total dry weight, leaf and stem, and essential oil percentage. Thymol and p-cymene were inversely correlated with carvacrol and gamma-terpinene.Conclusion: On the whole, to produce S. mutica under rainfed conditions similar to this study, manure or straw could affect yield and essential oil over the first and second years; however, in the third year, this effect diminished, and control treatment was superior to straw and manure treatments.

The genus Pycnocyla belongs to the Apiaceae family and has eight perennial species in Iran. In this study, the essential oil content and chemical compounds of P. nodiflora Decne ex. Boiss. and P. flabellifolia Boiss. were investigated. The aerial parts of plants at seeding stage were collected from two habitats in Hormozgan province through two consecutive years and Kermanshah province in one year, respectively. Stem+leaf [SL] and seed [S] were separated and shade-dried. The essential oil was extracted by Clevenger apparatus and hydrodistillation method for three hours. Percentage and chemical composition of the essential oils were determined by GC and GC/MS. The essential oil content of P. nodiflora was obtained [SL]: 0.23 and 1.21% (two years) and [S]: 0.23% in Tangzagh habitat of Hormozgan and [SL]: 0.02 and 0.06% (two years) and [S]: 0.01% in Abmah habitat. Caryophyllene oxid (7.8-28.1%) and b-eudesmol (15.5-57.2%) were recognized as the main compounds of [SL] and [S] essentials oils of both habitats in this species. In P. flabellifolia, the essential oil content of [SL] and [S] was 0.66 and 0.76%, respectively. The main compounds in [SL] essential oil of this species were cis-β-ocimene (33.8%), trans-β-ocimene (39.6%), and terpinolene (12.9%) and in [S] essential oil were trans-β-ocimene (28%), cis-β-ocimene (31%), and terpinolene (12.6%). According to previous reports on the antimicrobial properties of trans-β-ocimene and cis-β-ocimene compounds on bacteria like Staphylococcus aureus and S. epidermidis and the predominance of these compounds in the essential oil of P. flabellifolia, studies on antimicrobial properties of this species essential oil is recommended.

To investigate the effects of different nutritional treatments on morphological characteristics, essential oil yield, and the amount of some elements in the soil and plant branches of Satureja khuzistanica Jamzad, an experiment was conducted as a randomized complete block design with three replications and 14 nutritional treatments during two growing seasons (2017-2018, 2018-2019). Treatments included 1- C (control), 2- NPK (Chemical fertilizer 50-25-25 kg.ha-1), 3- CM30, 4- CM60 (CM: Cattle manure 30 and 60 ton.ha-1), 5- CM30+NPK, 6- CM60+NPK, 7- V5 (Vermicompost 50 ton.ha-1), 8- V5+NPK, 9- GM (Glomus mosseae), 10- GI (Glomus intraradices), 11- S0+T, 12- S250+T, 13- S500+T (S: Sulfur 0, 250, and 500 kg.ha-1, T: Thiobacillus), and 14- V5+T. The analysis of variance showed the significant effect (p < /em>≤0.01) of year×fertilizer treatments on the all morphological characteristics, percentage and essential oil yield, and the amount of potassium and sulfur of plant branches. The highest plant height in the first and second years was related to the CM30+NPK and CM60 treatments, respectively. The highest number of branches in the first and second years was observed in the CM30+NPK and GM treatments, respectively. The CM30+NPK treatment had the highest shade width in both years. Also, the highest amount of dry matter of flowering branches in the first and second years was related to the CM30+NPK and V5+T treatments, respectively. According to the results, the highest essential oil percentage in the first and second years was observed in the GM and S0 + T treatments, respectively. The application of V5+NPK and V5 +T treatments significantly increased the essential oil yield in the first and second years, respectively. The results also showed that the highest potassium content of branches in the first and second years was related to the GI and V5 + NPK treatments, respectively. Also, the highest sulfur content of branches in the first and second years was obtained in the V5 and S500 + T treatments, respectively. In general, the present study showed that the use of biofertilizers increases the efficiency of essential oil percentage and the amount of nutrients in this plant. Also, it could be recommended to use vermicompost along with the chemical and biological fertilizers to increase the essential oil yield of Satureja khuzistanica.

Two species Nepeta cataria L. and Nepeta bracteata Benth. (fam. lamiaceae) are native to Iran. To study the quantity and quality of the two species essential oil in the field, the seeds of eight populations from these two species were collected from natural habitats and planted in a randomized complete block design in Alborz Research Station of Research Institute of Forests and Rangelands (Karaj, Alborz province). The flowering branches were harvested at the full flowering stage and after room temperature-drying, their essential oils were extracted by hydrodistillation, and analyzed and identified by GC and GC/MS. The essential oil yield of N. cataria populations varied between 0.02 (Karaj) and 0.50% (Arak). Twenty-three compounds were identified in the essential oil of this species, and the main compound in all populations was from nepetalactone isomers. NepetalactoneIII (4aα,7β,7aα-nepetalactone) and nepetalactoneI (4aα,7α,7aα-nepetalactone) constituted 44.4 (Karaj) to 91.6% (Arak) and 0.8 (Karaj) to 15.9% (Bafgh1) of the essential oil, respectively. NepetalactoneII (4aα,7α,7aβ-nepetalactone) was observed only in the population Bafgh2 (21.2%). The amount of 1,8-cineole in the essential oil of different N. cataria populations varied from 0.4 (Taft1) to 12.8% (Karaj). The essential oil yield of N. bractaeta populations was obtained between 0.02 (Ardakan) and 0.70% (Taft2). Twenty-seven compounds were identified in the essential oil of this species, and the main compounds were 1,8-cineole (1.0, 9.6, and 41.0% in Tabas, Ardakan, and Taft2, respectively) and geranyl acetate (0.9, 3.4, and 39.8% in Tabas, Taft2, and Ardakan, respectively). In general, the results showed that the N. cataria populations were all from the same chemotype, but N. bracteata populations were from two chemotypes (ct. geranyl acetate and ct. 1,8-cineole).

The aim of this study was to investigate the effects of soil application of potassium fertilizer and foliar application of brasinosteroid on morphophysiological characteristics and essential oil yield of medicinal plant purple coneflower (Echinacea purpurea (L.) Moench) in response to water availability. Treatments consisted of three levels of water availability (irrigation at 90% (control), 60%, and 30% of field capacity (FC)) in main plots and four amounts of potassium fertilizer (no potassium application (control), 50, 100, and 150 kg K2O ha-1) as well as the foliar application of three brassinosteroid concentrations (distilled water (control), 0.1, and 1 μM) in subplots. Results showed that the highest mean plant height (67.8 cm), number of leaves plant-1(151), number of flowers plant-1 (18.1), flower dry weight (151.9 g plant-1) and aerial parts dry weight (508.6 g plant-1) were obtained in the second year of the experiment under 150 kg ha-1 potassium and normal irrigation treatments. The highest percentage of essential oil (76) was obtained under irrigation at 60% of FC, 150 kg ha-1 potassium, and 1 µM brassinosteroid treatments. In the second year, the maximum amount of essential oil plant-1 (0.67 g) was related to 150 kg ha-1 potassium and 1 μm brassinosteroid treatments. In general, the results of this study showed that irrigation at 60% of FC together with 150 kg ha-1 potassium and 1 μM of brassinosteroid could reduce the effects of drought stress, increase the amount of essential oil plant-1 and improve some morphophysiological characteristics in purple coneflower.

Two species of Nepeta assurgens Hausskn. & Bornm. and N. eremokosmos Rech., are endemic medicinal plants to Iran. This study was conducted to investigate the vegetative traits, aerial parts yield, the quantity and quality of essential oil, as well as evaluating the relationships between these traits in mentioned species under field conditions in Isfahan. The experiment was carried out in a randomized complete block design with three replications over 2017 and 2018. Results showed that the fresh and dry weight of aerial parts in N. assurgens (11353 and 2351 kg ha-1, respectively) was remarkably higher than that of N. eremokosmos (2638 and 527 kg ha-1, respectively). The average content and yield of essential oil in N. assurgens and N. eremokosmos was 1.60 and 0.64%, and 20.16 and 2.21 kg ha-1, respectively. Based on qualitative analysis of essential oil, the total amount of nepetalactone isomers (4aα, 7α, 7aα-nepetalactone, 4aα, 7α, 7aβ-nepetalactone, 4aα, 7β, 7aα-nepetalactone) in N. assurgens and N. eremokosmos was 78.6 and 62.8% on average, respectively. Correlation analysis showed that leaf dry weight, total fresh and dry weight, and large diameter of the plant had the highest correlation with essential oil yield. Stepwise regression analysis indicated that essential oil yield changes were mainly explained by leaf dry weight, essential oil content, total fresh weight, the number of stems and the amount of plant crown cover. In general, according to the results, the superiority of the N. assurgens species was significant and could be recommended as a valuable and high potential yielding plant for pharmaceutical purposes.

One of the most important methods of conservation and survival of plants in nature is the cultivation and domestication of plant species to select the best population. According to the necessity of cultivating and domesticating medicinal plants, in this research, 22 accessions of Achillea wilhelmsii C. Koch were planted and evaluated in the Alborz Research Station, Research Institute of Forests and Rangelands. This research was performed in a randomized complete block design during 2013-2015. In order to study and compare the morphological characteristics of different accessions of this plant, the plant height, canopy cover, number of main stems, number of capitol per plant, number of florets in capitol, plant fresh and dry weight, and essential oil content were measured at 50% flowering. The extraction was carried out by water distillation method with Clevenger. Analysis of variance and mean comparison showed that the difference among the accessions was significant at 1% level. The results showed that Saqez 1 had the highest plant height, plant dry weight, number of capitol and florets and essential oil content. The correlation between the study characteristics was significant at 1% level; however, no significant correlation was found between essential oil content and other characteristics except for the number of capitol. Using the principal component analysis, the first five components explained 99% of the total variance of the variables. Canopy cover, plant height, number of stems, number of capitol, and plant fresh and dry weight, with a positive coefficient, had the most important role in explaining the first component and explained 75% of the variance of the variables. In the cluster analysis, the accessions were divided into three groups, and the Saqez1 accession was placed in a separate cluster as an indicator.

Treatment of Staphylococcus aureus (S. aureus) infection is a problematic subject in the world. The aim of this study was an evaluation of the antimicrobial effect of four species of Satureja essential oils on biofilm formation and hemolysin production in S. aureus. MIC of Satureja essential oils (Satureja khuzistanica Jamzad, Satureja bachtiarica Bunge, Satureja rechingeri Jamzad, Satureja mutica Fisch. & C. A. Mey.) were determined by micro dilution broth method against standard strains of S. aureus ATCC 29213(MSSA) & ATCC 33591(MRSA). Sub- MICs of Satureja essential oils were used to assay biofilm formation and hemolysin production. The results showed that all essential oils had antimicrobial effect against standard strains of S. aureus. In the presence of sub- MICs of essential oils, biofilm formation and hemolysin production were significantly reduced. The results show the potent antimicrobial effects of Saturejaessential oils against S. aureus and more study is recommended to use it in controlling S. aureus infections.

To evaluate biomass and oil percentage at flowering stage in different accessions of medicinal plants Satureja spicigera (C. Koch) Boiss. (spic1, spic2, spic3)and S. sahendica Bornm. (sah1, sah2, sah3, sah4, sah5, sah6)under dry farming condition, an experiment was carried out based on three-replicated randomized complete block design in Damavand, Iran in 2014. Variance analysis showed significant differences (P<0.01) between two species for all the traits with the higher values for S. spicigera. Based on means comparison, higher dry shoot weight per plant(108.5 g) was detected in S. spicigera compared to S. sahendica with 25.82g. The highest amount of dry shoot weight per plant was obtained from spic2 accession (183.5g) in S. spicigera and from sah2 (45.51 g) in S. sahendica.Also, S. spicigera showed higher oil content (2.65%) compared to S. sahendica with 1.34%. Spic2 with the highest amount of oil (2.90%, 36.10 kg/ha) could be the best accession for cultivation under dry farming condition of Damavand. Considering lower plant canopy diameter in S. sahendica (32.19 cm) compared to S. spicigera (54.90cm), biomass and oil yield increase is possible with higher plant density. Furthermore, considering dry shoot weigh, plant height, plant canopy and day to flowering as selection indices, sah2 could be proposed as superior genotype of S. sahendica for dry land farming in Damavand or similar climates.

The genus Achillea, with 19 different species, is a perennial and herbaceous plant with aromatic properties. Achillea biebersteinii Afam. has medicinal properties and commonly used as a medicinal plant. Different parts of Achillea have anti-bacterial, anti- inflammation, anti- allergy and antioxidant usage in tradition and modern medicine. In order to compare the quality and quantity of essential oils of flowering shoot, the seeds of Achillea were collected from Golestan province and cultivated in the farm of Abolrz Research Station. Aerial parts (flower, leaf and shoot) were separately collected and dried in shade condition. The essential oils were extracted using hydro-distillation method and analyzed by GC and GC/MS. The highest and lowest essential oil yield was recorded for leaf (0.74%) and shoot (0.03%), respectively. The total essential oil yield of flowering shoots and flowers were 0.6% and 0.34%, respectively. The major components in the shoot essential oil were 1,8-cineole (15.1%), camphor (24.0%); in leaves:1,8-cineole (40.4%), artemisia ketone (28.1%), camphor (10.3%); in flowers: 1,8-cineole (41.3%), (24.3%), camphor (15.6%); and in flowering shoots: 1,8-cineole (35.4%), artemisia ketone (30.6%), camphor (16.2%). Based on the results of this research, the highest amount of artemisia ketone and camphor were found in the flowering shoots and the highest amount of 1,8-cineole in leaves and flowers.

In order to study the essential oil content and composition of different accessions of Anthemis haussknechtii Boiss. & Reut, the seeds were collected from Kordestan, west Azarbaijan, Ilam and Fars provinces and sown at Alborz research station during 2013-2014. In the flowering stage, the flowering shoots were harvested and air died. The essential oil was obtained by hydro-distillation method and analyzed and identified by GC and GC/MS. Results showed that the essential oil yield of Piranshar and Darehshahr was 0.2% and 0.03%, respectively. Twenty eight components were identified in eight accessions and differed in number, type and percentage. The main components of essential oils were spathulenol in Darehshahr, Ghorveh, Divandareh2, Ivan, Piranshahr and Sanandaj (19.1, 18.1, 16.2, 14.5, 13.8 and 12.2 percent, respectively), caryophyllen oxide in Darehshahr, Ghorveh, Divandareh2, Fars and Divandareh1 (20.5, 13.2, 12.9, 12.4 and 12.2 percent, respectively) and globulol in Ivan, Divandareh2 and Ghorveh (12.0, 11.5 and 11.2 percent, respectively). Cluster analysis showed that eight essential oils of different populations were classified into three categories including Piranshahr-Fars, Ghorveh-Darehshahr and others. According to the results, to obtain some high-percentage components, it is essential to extract the essential oil from a specific population.

Tanacetum polycephalum, belonging to the Asteraceae family, is a perennial and aromatic species with numerous medicinal properties. In this study, in order to evaluate and compare the quality and quantity of essential oil of flowering shoots and each of its parts (flowers, leaves and stems), the seeds of T. polycephalum Schultz. Bip. Subsp. polycephalum was collected from Kurdistan province (around the Qorveh city) and cultivated in the Alborz Agriculture Research Station, associated to the Research Institute of Forests and Rangelands. After collecting the aerial parts in full flowering stage, organs were separated and dried in the shade and essential oil extraction was carried out by hydro-distillation. The essential oils were analyzed by using a gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The highest yield of essential oil (W/W relative to dry weight) was obtained from flowering shoots (0.87%) and the lowest yield was obtained from stems (0.12%). The oil yield of leaves and flowers was calculated to be 0.61% and 0.46%, respectively. The main compounds in the oil of flowering shoots were camphor (35.5%), cis- chrysanthenol (10.1%) and α-terpinene (9.5%). Camphor (25.4%), α-terpinene (13.2%), and cis-chrysathenol (11.2%) were found in the essential oil of leaves. Trans-β-farnesene (39.7%) and camphor (8.5%) were the main components in the essential oil of stems. According to the results, if camphor and cis-chrysanthenol is the target of essential oil extraction, distillation from flowering shoots and leaves is recommended; however, to achieve the most amount of trans-chrysanthenyl acetate, distillation from flowers is recommended.

Due to the increased use of medicinal plants, the qualitative classification is inevitable. Rosa damascena Mill. with a high value of essential oil and its unique properties in the health, food and pharmaceutical industries is of one of these plants. In this study, after essential oil extraction from nine genotypes of Rosa, the essential oil components were identified by GC and GC-MS analysis. The genotypes were divided in three classes (C1, C2, C3) based on total percentage of six most important compounds, having major role in essential oil quality (phenyl ethyl alcohol, trans rose oxide, citronellol, nerol, geraniol, geranial).Then, the classes were tested by an electronic nose (EN) system designed based on metal oxide semiconductor (MOS) sensors. Sensors response pattern was recorded and analyzed by chemometrics methods in next step. Results of principal components analysis (PCA) showed that 85% of data variance was explained by two first principal components (PC1, PC2). Artificial neural network based on back propagation multilayer perceptron (Bp-MLP) was performed and classification accuracy achieved 100% and 96% for training and test sets, respectively. These results showed that EN could be used as a quick, easy, accurate and inexpensive system to classify Rosa damascene Mill essential oil.

The Sahandi savory (Satureja sahendica Bornm.) is a native medicinal species of Iran, which is exposed to extinction. Organic farming of this species in low input systems has an important role to protect this valuable genetic reserve. To evaluate the essential oil content and components of the savory in natural habitat and field conditions, an experiment was conducted to investigate the plant growth responses to different fertilizer and redroot pigweed (Amaranthus retroflexus L.) density (0, 6, 12 and 18 plants/m2) in two planting patterns (rectangles, zigzag). The experiment was carried out in factorial based on RCBD with three replications at the Qazvin Agriculture and Natural Resources Research Center during 2010 to 2012. The nutrient treatments included NPK plus foliar application of micronutrients, four tons/ha vermicompost, two tons/ha vermicompost plus 40 liters/ha vermi-tea (liquid formulation of vermicompost). At the flowering stage, the essential oil content and compounds were measured in both samples of field and natural habitats. The effect of planting pattern was not significant. The highest content of essential oils in first harvest (28.38%) and in second harvest (46.04%) were obtained from organic fertilizer treatments, two tons vermicompost + 40 liters vermin-tea and four tons vermicompost, respectively. These treatments were superior to the savory harvested from natural habitats. The essential oil content of savory under competition of redroot pigweed at all densities were higher than the natural habitats and the highest content in first and second harvest (30.41% and 51.80%) was obtained at 18 plants/m2 pigweed density. In all fertilizer treatments, the content of thymol in comparison to natural habitats (38.49%) was superior and the highest content (42.95%) was obtained with application of four tons vermicompost. In the absence of weed, the Sahandi savory produced the greatest content of thymol (45.18%) compared to the savory grown in natural habitats.

Zinc is an essential micronutrient element and has a number of vital roles in plants. In the recent years, zinc nano-fertilizers have received considerable attention due to their increased uptake by plants as they are small in size and have high rate of penetration through plant cell membrane. To study the effect of foliar application of different zinc fertilizers on yield and phytochemical characteristics of basil (Ocimum basilicum L.), a pot experiment was conducted using a factorial based on a randomized complete block design with four replications during 2014 at the experimental greenhouse of the Horticultural Sciences Department of Urmia University. The treatments were three different zinc sources (zinc sulphate, zinc chelate and nano-zinc chelate) in four concentrations (0, 1, 2 and 3g/l). The results showed that foliar application of zinc had significant effect on evaluated parameters. Fresh and dry herb yield, zinc and phenol content of leaves, essential oil content, and yield increased with zinc application and in this regard, foliar application of nano-zinc chelate was more effective than two other zinc fertilizers. The lowest and the highest evaluated parameters were observed at concentrations of 0 and 3g/l, respectively. The results of essential oil analysis by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) showed that 20 components were identified in the basil essential oil. Linalool and eugenol were the main components of essential oil and they showed little variation under zinc application. Overall, the findings of this study showed that the effect of nano-zinc chelate application (especially at a concentration of 3g/l) was more effective than zinc sulphate and zinc chelate in increasing herb yield and active substances of basil.

To determine the quantitative and qualitative characteristics of six dragonhead (Dracocephalum moldavica L.) populations at six habitats, an experiment was conducted as completely randomized design with three replications (at intervals of 500 to 1000 m) in 2013. Each dragonhead population belongs to a habitat including Salmas, Urmia, Khoy, Maragheh, Piranshahr and Tabriz. The szk-1cultivar, as a control treatment, was planted in the Research Field of Payam Noor University (PNU) in Marand. In each habitat, flowering branches of dragonhead were collected in full flowering stage. In this study, some traits such as plant height, number of branches, number of flowering branches, essential oil content, nitrogen, phosphorus, and potassium in shoot as well as chlorophyll contents (a, b and total), carotenoids, flavonoids and anthocyanins were measured. According to the obtained results, the effect of habitat was significant on plant height, number of branches, essential oil, the amount of nitrogen, phosphorus, chlorophyll and flavonoids at 5% level as well as on number of flowering branches and anthocyanin amount at 1% level. Results showed that the highest plant height and nitrogen, phosphorus, chlorophyll, carotenoids and essential oil contents were obtained from Salmas population. The Szk-1 cultivar produced the highest number of lateral and flowering branches and total flavonoids in Marand. In general, Salmas population had the best growth characteristics and qualitative traits. Therefore, this population could be used to produce varieties with desirable agronomic properties.

Anthemis, belonging to Asteraceae family, has 23 native annual species in Iran whose flowers and other organs contain essential oil. To study the quantitative and qualitative characteristics of the Anthemis pseudocotula Boiss. essential oil, the seeds were collected from natural habitat in Maraveh Tapeh, and planted in the Alborz Research Station. In full flowering stage, samples were prepared from plant flowers, leaves, stems and flowering shoots. After air-drying, the essential oil was extracted by hydro-distillation method and analyzed by GC and GC/MS. According to the obtained results, the essential oil yield of flowers, leaves, stems, and flowering shoots were calculated to be 0.06, 0.02, 0.06, and 0.06-plant dry weight. Twenty-three components were identified in the leaf essential oil whose main components were β-thujone (27.3%), cadin-4-en-7-ol (cis) (11%), caryophyllene oxide (10%) and β-eudesmol (6.7%). In the stem essential oil, 14 components were identified and Z-β-farnesene (62.4%), lavandulyl and 2-methyl butanoate (12.4%) were the two main components. The three main components identified in the flower essential oil were β-thujone (33.6%), spathulenol (20.3%) and Z-β-farnesene (9.5%). The three main components identified in the flowering shoots were β-thujone (34%), Z-β- farnesene (12.3%) and caryophyllene oxide (12.3%). The results showed that β-thujone as a main component of essential oils ranged from 3% in leaves to 34% in flowering shoots. Our results clearly showed that more essential oil yield could be obtained from the flowering shoots of Anthemis pseudocotula at full flowering stage. As well, the desired parts could be extracted to obtain higher amount of essential oil components for specific objectives.

About 67 species of the genus Nepeta have been found in Iran and Nepeta pogonosperma Jamzad is endemic to Iran. In order to investigate the effect of water deficit on Nepetapogonosperma, an experiment was conducted under field conditions in 2015, at the Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was conducted in a randomized complete blocks design with three replications. Treatments consisted of three levels: 30, 60, and 90% of field capacity. Harvesting was done in full flowering stage. Essential oil was extracted by distillation for 2 hours and 30 minutes. The percentage of essential oil components was determined using GC and GC/MS. In the Nepeta pogonosperma Jamzad essential oil, 16 components were identified and the highest percentage of 15 components including α-thujene, α-pinene, sabinene, β-pinene, myrcene, α-terpinene, ρ-cymene, e-β-ocimene, γ-terpinene, terpinen-4-ol, α-terpineol, 4aα,7α,7aα-nepetalactone, 4aα,7α,7aβ-nepetalactone, E-caryophyllene and β-bisabolene was related to the control treatment. Analysis of variance revealed that water deficit significantly affected the essential oil percentage, yield, and components detected. The highest essential oil percentage with an average of 3.18% belonged to the severe stress treatment (30% FC). The highest oil yield (78.321 kg per hectare) was recorded for the moderate stress treatment (60% FC). The highest content of 1.8-cineole belonged to 30% FC. The highest total content of nepetalactone with an average of 28.2% was obtained in the control group. Our results clearly showed that severe and moderate water deficit stress could be recommended for the production of plants with high essential oil content. However, no water deficit stress is recommended to obtain high content of nepetalactone.

The genus Nepeta is one of the largest genera of the Lamiaceae family, and Iran, particularly, is one of the main centers of origin of this genus. Nepetalactones and flavonoids were reported as major constituents of Nepeta species, and the main cause of their medicinal value and biological properties. There are lots of reports related to biological activities of secondary metabolites of genus Nepeta showing the importance of this genus. In this work, the essential oil (EO) diversity of 21 wild populations from Nepeta kotschyi Boiss., Iranian endemic species, was investigated. For removing the environmental effect, the seeds of populations were planted in one place. Plant aerial parts were harvested at full flowering stage, and after shade-drying, their EO was extracted by hydrodistillation method. EO was quantitatively and qualitatively analyzed by GC and GC/MS. After botanical study and EO analysis, it was revealed that the populations were from two different varieties. Two populations including buyer-ahmad1 and Buyer-Ahmad2, were from N. kotschyi var. kotschyi, and others were stood in N. kotschyi var. persica. Twenty-four components were characterized in the EO of N. kotschyi. The highest amount of EO yield (w/w) was obtained in populations of var. kotschyi (0.5-0.7%). Three main chemotypes were identified among populations of var. persica based on the main component(s) of EO, including a containing NepI (4aα,7α,7aα-nepetalactone), b containing NepII (4aα,7α,7aβ-nepetalactone) and cubenol, and c containing geranyl acetate and cubenol. Except of semirom and Taft5 which were stood in b-chemotype, and Taft4 which was placed in c-chemotype, other populations of var. persica, also populations of var. kotschyi, were stood in a-chemotype. In addition, based on the main component of EO, the populations of var. kotschyi were put in a-chemotype. In a-chemotype, the amount of NepI was obtained between %53.9 (Chelgard) and %84.8 (Buyer-Ahmad2), and NepII was measured between %1 (Taft1) and %13.7 (Chelgard). In b-chemotype, the amount of NepI was measured between %0.3 (Taft5) and %4.9 (Semirom), and NepII was obtained between %13.4 (Taft5) and 44.7% (Semirom). NepIII (4aα,7β,7aα-nepetalactone) (1.3-3.3%) was characterized only in the EO of var. Kotschyi populations.

In order to study the effects of zeolite, bio and organic fertilizers on the growth, yield and yield components of German Chamomile (Matricaria chamomilla L.) in organic cultivation, an experiment was conducted at the research field of Tarbiat Modares University in 2005. The factors were PGPR inoculums (inoculated and no inoculated), zeolite (0 and 9 ton/ha) and vermicompost (0, 5, 10 ton/ha). The experimental design was factorial in a randomized complete blocks design with twelve treatments and three replications. Mean comparison was carried out using Duncan’s multiple range test (at 5% level). Results showed that the highest value of flower yield (358.13), biological yield (1572.09), number of flower per plant (61.09), flower diameter (21.84) and height (45.51) were obtained with PGPR inoculums. Zeolite also showed significant effects on mentioned traits except flower diameter and harvest index. With increasing of vermicompost levels, all traits were increased as the highest value of flower yield (434.22), biological yield (1814.30), number of flower per plant (72.71), flower diameter (22.35) and height (47.91) were obtained with application of 10 ton/ha vermicompost. In addition, there were positive and synergistic interactions between vermicompost combined with PGPR and vermicompost combined with zeolite on dry flower yield, as the highest flower yield was obtained in v3b2 and v3z2 treatments with 448.73 and 448.7kg/ha, respectively.
