Didar (Euphorbia tirucalli L.) from the family Euphorbiaceae, is a perennial succulent shrub with broad branched and round branches. Environmental factors are one of the most important factors affecting qualitative and quantitative traits in medicinal plants. In this study, Didar was studied in different habitats of Sistan and Baluchestan province in terms of some morphological, physiological, soil, and phytochemical characteristics. This study was conducted as a nested design and Duncan's least significant differences test at 5% level with completely randomized design with three replications using field survey and included some cities: 1- Hichan district from Nikshahr city (Kalat, Hesarak and Hashtik villages), 2- Rask city (Firoozabad, Jangal and Parood villages) and 3- Sarbaz city (Hit, Kishkour and Pirdan villages). The results showed that there was a significant difference between all the studied traits among cities and regions. In this study, morphological traits had the highest amount in Nikshahr city and the lowest height and number of branches belonged to Sarbaz city, indicating that the vegetative growth of this shrub decreases with increasing altitude. The soil studied in Nikshahr city regions was more favorable than other areas in terms of key elements such as phosphorus and potassium. The highest levels of 1- chlorophylls a and b and carotenoids and 2- proline and flavonoids were measured in spring and summer, respectively, but the highest amount of anthocyanin was observed in different cities variably. The highest amounts of 1- chlorophylls a and b and 2- carotenoids and anthocyanin were measured in Sarbaz and Rask cities, respectively. The highest amount and number of active ingredients of leachates of this plant were observed in summer.

This study was carried out to investigate different soil fertility management on morphological traits, essential oil yield and quality of fennel (Foeniculum vulgare Mill) forage. The experiment was conducted as a randomized complete block design with three replications at the Research Institute of Forests and Rangelands. The experimental treatments included five fertilizer levels (chemical, biological, vermicompost, 75% and 50% concentration of chemical fertilizers + bio-fertilizers + vermicompost). The results indicated the significant effects of different fertilizer treatments on the traits studied. Accordingly, the treatment of 75% chemical fertilizers with biofertilizers and vermicompost improved morphological characteristics, essential oil yield, and quantitative and qualitative yield of forage, recognized as superior treatment. The above mentioned treatment had the highest plant height (95 cm), shoot dry weight (98 g m-2), biological yield (1191.6 kg ha-1), seed yield (138 kg ha-1), and harvest index (11.6%). The highest and lowest percentage and essential oil yield were related to 75% chemical fertilizers+biofertilizers+vermicompost (about 3% and 18 kg ha-1) and 100% chemical fertilizers treatment (about 2% and 13 kg ha-1), respectively. The highest amount of important forage qualitative traits such as digestible dry matter (%), water soluble sugars (%) and ash content was obtained in 75% chemical fertilizers with biofertilizers and vermicompost treatment. While the above mentioned traits had the lowest amount in the application of 100% of chemical fertilizers, compared to other treatments. In addition, forage quality-reducing factors such as neutral and acidic insoluble fiber had the highest values in this treatment. It seems that in order to achieve sustainable agriculture and optimize the organic production of medicinal plants, the reduced concentrations of chemical fertilizers along with bio-resources can reduce environmental pollution in addition to economic production.

The biological control of plant pathogens is a priority for reducing of the dangerous effects of chemical pesticides that are include threats for human health, environmental pollution, and the emergence of pathogens resistant eliminates. Ceratocephalus falcatus L. such a buttercup, plant is very small annual plant, 3-5 cm tall, it has short stems. Plant samples were collected based on completely randomized design with three replications in May 2015 from the village of Buzhmehran (city of Neyshabur) to record of morphological, phytochemical characterization such as total phenol, total flavonoids and antioxidant water extract, methanol and acetone plant the fungus Fusarium graminearum. The number of flowers per plant on average 5 numbers, leaf number was 19 and the plant is 3 cm tall. The total phenol Gallic acid 0/098 mg per gram of dry weight, the flavonoids quercetin 0/302 mg per gram of dry weight and percent free radical scavenging antioxidant activity it was determined 70/618. The effect of the extracts on the fungus Fusarium graminearum were showed that the most-linear growth of mycelium to control the methanol extract had the lowest. As a result, methanol extracts percent more on linear growth inhibition was assessed fungus can be concluded that Ceratocephalus falcatus has antifungal properties and enjoys good standing in study programs.

In order to investigate the effects of different irrigation intervals on morphological characteristics of different Achillea millefolium L. populations, an experiment was conducted at the experimental field of Research Institute of Forests and Rangelands during 2012 and 2013. Three irrigation intervals (7, 14 and 21 days) and 19 A. millefolium populations were compared in a factorial experiment based on a complete randomized block design with three replications. As many plants were lost in irrigation interval of 21 days, comparison was continued with irrigation intervals of 7 and 14 days. Results showed that irrigation intervals and population origins had significant effects (P≤0.005) on the plant height, crown diameter, stem number, dry matter yield (g plant -1 ), flower diameter, flower number and flowering time. In almost all populations the plant height, crown diameter and flower diameter decreased, whereas flower number per plant and the full flowering time increased in irrigation interval of 14 days. The 19 populations were grouped into three clusters. Populations in the cluster I had higher plant height, yield and flowering time. Populations in the cluster III showed higher crown diameter, flower diameter, stem number and flower number, and shorter full flowering time. These results indicated that populations in the cluster III had favorable potential production in semi-arid regions.

Achillea L. is one of the most important native medicinal genuses of Iran. Morphological and agronomic traits in 27 populations of A. millefolium and in 14 populations of A. bieberestini were studied using a random complete blocks design with three replications in Alborz Research Center, Karaj, Iran. ANOVA suggested significant differences among 27 populations of A. millefolium for all morphological and agronomic traits except full flowering time. Significant differences were found among 14 populations of A. bieberestini for all morphological and agronomic traits. In both species of A. millefolium and A. bieberestini significant correlation coefficient were found between the plant height and the flower diameter. Comparison of dry matter yield and other characteristics of different populations indicated that populations with dry and hot origin in both species of A. millefoliuum and A. bieberestini had better productivity. Population Semnan (21657) in A. millefoliuum and population Park golestan in A. bieberestini showed better characteristics in plant height, plant diameter, main inflorescence diameter, dry matter yield and inflorescence number as compared with other populations, which could be suggested for breeding programs.

Summer savory (Satureja hortensis L., Lamiaceae) is a well known medicinal and aromatic plant, native to Southern Europe, Anatolia, Caucasus, Iraq and western Iran, but nowadays it is cultivated worldwide. In order to evaluate the effect of sowing date and plant density on the yield and morphological characteristics of Satureja hortensis L. a field experiment was conducted in Sary Agricultural University using split-plot design based on randomized complete blocks with three replications during 2010. Main factors were three sowing dates (11 April, 22 April and 3 May) and sub factors were three plant density (15×35, 25×35 and 35×35cm). The species were investigated at full flowering stage. Sowing date and plant density had significant effects on most of the morphological characteristics. According to the results of mean comparison, the highest plant height (52.3 cm), lateral shoot (23.22 N/P), number of nod (17.81), shoot diameter (8.8 mm), root diameter (9.12 mm) and dry weight of root (2.76 g/p) were recorded for first sowing date. Delay in sowing time increased the dry shoot yield significantly as the highest dry shoot yield (3023.1 and 2663.9 kg/ha) was obtained at third and second sowing time. The result of mean comparison showed that the highest root diameter (9.33mm) and dry weight of root (2.56 g/p) were recorded for third density. In addition, the highest plant height (53.03 and 51.09 cm), lateral stem (21.94 and 21.79 N/P), number of nod (17.06 and 16.32) and shoot diameter (7.92 and 7.4 mm) were obtained at third and second densities. Plant density had no significant effect on dry shoot yield. The obtained results showed that morphological characteristics of Satureja hortensis were affected by agronomic treatments and growth performance may be enhanced by proper management.
