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.

Rosa damascene Mill. wascollected from west parts of Iran, and cultivated at the experimental field of Research Institute of Forests and Rangelands, using a three replicated randomized complete blocks design. Seven genotypes, were compared for essential oils yield in 2003 and for petal, stamen, and pistil number, in 2003-2004. Genotypes showed significant differences in terms of the measured traits. Comparison of means classified the genotypes in 7, 7 and 7 (in 2003) and 6, 7 and 6 (in 2004) groups, for petal, stamen and pistil number, respectively. Also, essential oils concentration and yield showed genotypic variation. A considerable variation was, therefore, revealed from different analyses in floral parts and essential oils concentration of Rosa damascena Mill. from west parts of Iran. It could then be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, concentration and yield of essential oils as the most important product of Rosa damascena Mill., and also some of the related traits, such as floral parts could be used as appropriate selection factors for classification of damask rose genotypes, in order to use in breeding program.

Nepeta, belonging to Lamiaceae family, includes 250 species in the world and 67 species in Iran, 39 of which are native to Iran. In order to investigate the effects of drought stress on yield quantity and quality of Nepeta racemosa Lam., this experiment was conducted in 2011, at the Alborz Research Station, Karaj, Iran. Drought levels were 100% (control), 80% (low stress), 60% (medium stress), and 40% (severe stress) field capacity (FC). Different traits including plant height, number of tillers, number of lateral branches, root weight, root length, main stem diameter, number of inflourcences, inflorescence length, leaf length, leaf width, yield of leaf, inflorescences, stem and shoot, and essential oil percentage and yield of leaf, inflorescence, stem and shoot were measured at flowering stage. Variance analysis revealed significant effect of drought stress on plant height, root weight, inflorescence length, leaf length, leaf width, yield of leaf, stem, inflorescence, and essential oil percentage of leaf, stem, inflorescence, and essential oil yield of the leaf, stem, inflorescence (P≤0.01), root length, and main stem diameter (P≤0.05). Mean comparison showed that the highest essential oil percentage was observed in leaves (1.72%), shoot (1.27%) and inflorescences (1.93%) at medium stress (60% field capacity). It could be concluded that Nepeta is a drought tolerant plant, and the maximum essential oil percentage could be achieved under medium stress with 60% field capacity.

In order to investigate of water requirement in Rosa damascene Mill., an experiment was carried out in the Alborz Research Center in 2012. The lysimeters with drainage system were used for Rosa damascene (adult plant), Medicago sativa (reference plant) and control group (only soil). For each lysimeter, the soil moisture content was measured by weighting method before and after applying irrigation treatments based on the field capacity. The amount of water requirement and run-off were measured in each lysimeter. The evapotranspiration of Rosa damascene (ETc) and reference plant (ETo) was estimated by lysimeter. The plant coefficient of Rosa damascene (Kc) was calculated by ETc/ETo ratio. In order to comparison of lysimeter data with indirect methods, the Blaney Criddle and Penman-Monteith methods (corrected by FAO) were used to determine the evapotranspiration in reference plant. According to the obtained results, WUE and ETo in Rosa damascene were calculated to be 2.18 and 46.0, respectively. The evapotarnspiration of Rosa damascene after 820 GDD in full flowering, was 111 mm. The ETc after 3740 GDD in the late stage was estimated to be 1147 mm. The evapotarnspiration of reference plants, after 3833 GDD, in lysimeter, Blaney Criddle and Penman-Monteith methods were 1247, 1392 and 1160 mm, respectively. Based on results, a similar estimation of ETo content was obtained by lysimetr and computational methods.

In order to identify the best genotypes of rose (Rosa damascene Mill.), a field experiment was conducted in a randomized completely blocks design with seven treatments and three replications. Flower number, flower fresh weight, yield, petal fresh weight, petal to flower fresh weight ratio, petal number, flower diameter, flowering period, essential oil weight were investigated for seven genotypes of rose (Fars1, Fars2, Darab1, Darab2, Darab3, Estahban1, Meymand). Essential oil was obtained by distillation method and essential oil composition was determined by GC and GC/MS. Data analysis was performed by SAS and Jamp4. According to the results of mean comparisons, the highest yield and flower number were recorded for Darab1, Meymand and Fars2, while the highest amount of essential oil was obtained for Maymand and Fars2. A positive and significant correlation was also found between yield and flower number, leading to the increased essential oil. Citronellol, neral, and n-nonadecane were identified as the major components of the essential oil, respectively found in Darab1, Darab3, and Estahban1.

Because of the economic and medicinal importance of Rosa damascena Mill. the propagation of this plant was considered. In order to protect the selected genotypes, this experiment was performed by simple layering method during autumn and winter seasons 2007 on new growth twigsof Rosa damascena mature shrubs. The branches were laid in sand bed, soaked for 24 h by different concentrations of IBA and NAA hormones. The results showed that the rate of rooting was high in sand bedding material in autumn and winter. The highest rooting percentage was %100 with 50 mgl-1 concentration of IBA in autumn and winter seasons and the lowest of rooting percentage was %53.33 with 50 mgl-1 concentration of NAA in autumn season. The rooting branches were cut from the parent plants after 3 months and planted in pots containing soil: sand: peatmoss complex (1:1:1) in greenhouse conditions, survival percentage was 90%.

To evaluate 17 Damask rose genotypes regarding their variation for morphological traits, an experiment was conducted at the experimental field of Research Institute of Forests and Rangelands. Analysis of variance, mean comparison and phenotypic correlation analysis were performed. The variance analysis showed significant differences among genotypes for plant height and flower number per branch (P<0.01), number of leaves per branch, leaflet length and thorn density (P<0.05). Also, comparison of means classified the genotypes for the above characteristics. Significant correlations were observed between different traits. A significant (P<0.01) phenotypic correlation (r=0.96) indicated a strong positive relationship between flower yield and number of flower per plant. From the results, a wide range of variation was observed among the genotypes. Morphological characteristics could, therefore, be useful criteria for selection for yield. However, more genotypes, as well as further analyses, including flower quality especially essential oil components are necessary to be considered, in an efficient breeding of Rosa damascena.

Rosa damascenaMill. genotypes werecollected from central parts of Iran, and cultivated at the experimental field of Research Institute of Forests and Rangelands, using a randomized complete blocks design with three replications. Genotypes from six provinces were evaluated for essential oils yield and number of floral parts. Genotypes showed differences in terms of the measured traits. Essential oils concentration and yield showed variation. The most essential oils percentage (0.05%) and yield were observed in Isfahan7 and Yazd1 accessions, respectively, in 2002. Yazd2 and Isfahan6 accessions showed the highest essential oils percentage (0.03%) in 2001, and the most percentage of oils was observed in accession collected from Tehran, in 2003. Also, accession of Yazd1 demonstrated the highest 3-year mean of essential oils percentage and yield. Furthermore, the accessions showed variation for floral parts number. The highest numbers of petals and pistils were observed in accession collected from Tehran Province. Also, Isfahan10 accession showed the highest number of stamens. A considerable variation was, therefore, revealed for floral parts and essential oil content of Rosa damascena genotypes from central parts of Iran. It could then be concluded that the Rosa damascena genotypes differ for essential oils content and this may be applied for classification of Damask rose genotypes. Finally yield of essential oils as the major product of Rosa damascena could be considered as an appropriate selection factor, in order to improve rose varieties.

Rosa damascena from eight rejions in western parts of Iran, were cultivated at the experimental field of Research Institute of Forests and Rangelands, using three replicated randomized complete blocks design. Six genotypes were compared based on different traits including flower yield in 2003 and 2004.The obtained data was performed using ANOVA, (wich mean classification and correlation analyses). Genotypes showed significant differences in terms of the measured traits. Comparison in meaning, classified the genotypes in 4, 2, 3 and 4 groups, based on flower yield, flower weight, dry matter percentage and petal weight to flower weight ratio, respectively in 2003 and in 4, 2, 2 and 5 groups in 2004. It could be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, flower yield, flower number and dry matter percentage could be used as appropriate selection factors for classification of damask rose genotypes in western parts of Iran.

In order to study the genetic variation in Rosa damascena Mill., an experiment was conducted at the experimental field of Research Institute of Forests and Rangelands. Eleven genotypes were evaluated, using a randomized complete blocks design with three replications. Flower yield, flower number, single flower weight, plant height, canopy, branch angel, leaf number, spine density and spine length, were analyzed, using analysis of variance, principal components analysis and cluster analysis. The results showed significant differences among genotypes for all of the traits, indicating a considerable genetic variation in germplasm available in Iran. Using principal components analysis, the first three components determined 68.43% of the total variation. According to the cluster analysis, genotypes could be grouped into 3 clusters. Genotypes in cluster 1 averaged well above the overall mean for productivity and the other characteristics.

Rosa damascena Mill. genotypes from different areas of Iran, were cultivated at the experimental field of Research Institute of Forests and Rangelands, using a three replicated randomized complete blocks design. 11 genotypes were compared based on flower yield and morphological characteristics, including plant height, canopy, spine density , spine length, branch angel and leaf number. Evaluation of the obtained data was performed using ANOVA, mean classification and correlation analysis. Genotypes showed significant differences in terms of the measured traits. Comparison of means, classified the genotypes in 3, 4 and 3 groups, based on flower yield, flower number, and average flower weight, respectively. Also, the genotypes were classified in different groups, based on morphological characteristics. The results also indicated that there is a good relationship between some of the measured traits, particularly between yield and number of flowers. It could be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, flower yield and number and some of the morphological characteristics could be used as appropriate selection factors for classification of damask rose genotypes, in order to use in breeding programs.

This study was conducted in a greenhouse located at the Research Institute of Forests and Rangelands. The responses of genotypes of 3 Mentha species to salinity stress regarding rooting ability as well as other growth parameters, were evaluated, using a completely randomized design, based factorial design in 3 replications. Stem cuttings of 6 Mentha genotypes, including 28 and 3 (M. piperita L.), 6 and 31 (M. aquatica L.), and 11 and 17 (M. spicata L.) were grown in 0, 50, 100, 150 and 200 mM NaCl solutions. Rooting percentage, maximum root length, average root length, plant vigor, bud induction in saline water, maximum shoot length and shoot bud induction were measured 14, 21 and 28 days after cutting. The results showed that all of the above parameters were reduced with increase in NaCl concentration. However, there was a considerable variation for salt stress responses. All of the characteristics, particulary rooting percentage showed to be singificantly different in the salt treated genotypes, with the highest rooting ability in genotype 6 under 200 mM NaCl. Also, a positive correlation was observed between rootig percentage, as well as between the other parameters. The variation in growth components detected between genotypes, and the correlation between the traits, support a suggestion for breeding of mentha species of higher salt tolerance for cultivation under salinity stress.
