Jujube (Zizyphus jujuba Mill.) is a horticultural-medicinal plant belonging to the family Rhamnaceae. This research was conducted to evaluate the morphological traits and phytochemical compounds of jujube ecotypesin Iran to achieve superior medicinal ecotype. The plan with fourteen jujube ecotypes of jujube collection of Jahad University of Southern Khorasan (Birjand) was carried out in spring-2018 in a completely randomized design with three replications. Leaf and riped fruit samples were evaluated morphologically and phytochemically. The results showed that the yield of 100-seed weight was positively and significantly correlated with fruit length, fruit width and length to fruit width ratio. Also, length to fruit width ratio and length to leaf width ratio had a positive and significant correlation with leaf width. The correlation of total flavonoid and total phenol traits with other phytochemical traits was not significant. Antioxidant capacity was significantly correlated only with total phenol. Analysis of variance of morphological traits showed that the studied ecotypes had a significant difference with each other, which indicates the existence of a variety of jujube germplasm in Iran. Based on the cluster analysis results, fourteen ecotypes were placed in two separate clusters. The results of this study showed that there is a considerable diversity in the studied ecotypes that can be used in breeding programs of the species.

High demand for herbal medicines and the limited plant sources necessitates more research on these plants to increase their yield and effective compounds. The present study assessed the effect of biochar on yield and seed trigonelline content of fenugreek (Trigonella foenum-graceum L.) ecotypes under different irrigation regimes. Six branched fenugreek ecotypes including Dezful, Shushtar, Ardestan, Rehnan, Yazd and Khomeyni Shahr were treated by biochar application (at a rate of 7-8% of soil v/v) and non-application under two irrigation intervals of 4 (normal irrigation) and 8 (deficit irrigation) days using a split plot factorial experiment in a randomized complete block design with three replications. The study was conducted in the research field of Agricultural Biotechnology Research Institute of Iran in 2015. According to the results, biochar application increased the seed yield and biological yield under both irrigation intervals. The decreasing effect of increasing water intervals on seed yield, biological yield and trigonelline yield was observed in all ecotypes. Changes in seed trigonelline content did not follow a similar trend in different ecotypes. In summary, although biochar prevented the growth and yield reduction by decreasing water deficiency effects, itdid not have any significant effect on seed trigonelline content.

This study was aimed to evaluate the quantitative and qualitative performance of different populations of Milk Thistle (Silybum marianum L.( under the influence of autumn and spring planting season. Therefore, a split plot experiment was conducted including autumn and spring planting as main plots and four local populations (Shush, Poldoktar, Khoram Abad and Aleshtar) and a crop cultivar as sub plots. The study was carried out in the Faculty of Agriculture, Lorestan University, for two years 2014-2015. In addition, the native and crop populations of this species in Aleshtar were compared in a randomized complete block design. Based on the results, there was a significant difference between spring and autumn planting seasons. The highest plant height (107 cm), capitol diameter (44 mm), number of grains in capitol (78) and grain yield (1000 kg ha-1) were obtained in autumn planting. The interaction effect of planting season and population type showed that the highest content of silymarin (22 mg/g of dry weight) and silybin (3.9 mg /g of dry weight) was obtained from the crop cultivar in autumn planting. The comparison between native and crop populations in Aleshtar region showed that the highest content of silybin (4.2 mg /g of dry weight) and silymarin (more than 21 mg / g of dry weight) was recorded for native Aleshtar population compared with other populations. In general, it was determined that the highest and lowest quantitative and qualitative performance of Milk Thistle in the temperate region of Khorramabad was obtained in autumn planting, and the highest content of silymarin and silybin was recorded for the native Aleshtar population compared with other populations.

To study the effect of planting date and density on the yield, yield components and allicin content of two garlic ecotypes (Allium sativum L.), an experiment was conducted in a farmland in Damghan, Iran during the 2011-2012 growing season. The experiment was arranged as a split-split-plot in a randomized complete block design with three replications. Three planting dates (17-Oct, 11-Nov, 6-Mar) were main plots. Two ecotypes (Kavire Damghan and Hamedan) were subplots, and three planting densities (35, 45 and 55 plants per m2) were sub-sub-plots. The effect of planting date on plant height, fresh and dry weight of bulbs, yield, diameter and dry weight of cloves was significant, and delay in planting date decreased these traits. The values of dry and fresh weight of bulbs, plant yield, dry weight and diameter of cloves and allicin content were significantly higher in Hamedan ecotype in comparison with Kavire Damghan ecotype. The planting density had significant effect on fresh and dry weight of bulb and dry weight and diameter of cloves, as these traits were reduced by increasing the density. Furthermore, the effect of planting density on height and yield of plant and number of cloves in bulb was significant. To achieve the highest fresh yield (1.7kg.m-2) and dry yield (0.27 kg.m-2), 17-Oct was identified as the best planting date. Hamedan ecotype was more favorable as it had higher bulb fresh and dry weight, diameter and dry weight of cloves, allicin contents and yield. The most desirable planting density was 55 plants per m2 due to having higher values of plant height, number of cloves in bulb and yield.

Irrigation treatments were applied at two levels of 40% and 60% available soil water (ASW) depletion on Mashhad and Urmia ecotypes of two Lallemantia speciesincluding L. iberica Fisch. & C.A.Mey. and L. royleana. (Benth.) Benth. Increased available soil water depletion caused an increased seed mucilage percentage. The highest percentage of seed mucilage was obtained in 60% ASW depletion, L. royleana, and ecotype of Mashhad. The highest (11.22kg/ha) and lowest (6.25kg/ha) seed mucilage yield was obtained in 40% and 60% ASW depletion, respectively. In L. iberica, seed mucilage yield of Mashhad ecotype was 34.04 kg/ha higher as compared to Urmia ecotype. By increasing available soil water depletion, seed protein content decreased to 7.30% in L. iberica; however, it remained unchanged in L. royleana. Oil content was not affected by irrigation treatments. Oil yield of Mashhad ecotype of L. iberica was 41.5% higher as compared with Urmia ecotype. The highest grain yield (208.4kg/ha) was obtained at 40% available soil water depletion. The grain yield at 60% available soil water depletion (107.3kg/ha) decreased to 43.84% as compared to 40% available soil water depletion. Contrary to L. iberica, significant differences were observed among the ecotypes of L. royleana in terms of grain yield. In general, under deficit irrigation, seed mucilage percentage of balangu increased, however, the protein percentage decreased.

Jujube (Ziziphus jujube Mill.) is one of the medicinal plants containing mucilage and is used in the fields of pharmaceutical, medical, healthcare and industrial purposes. In evaluation of medicinal plants, secondary metabolites could be considered as a valuable indicator. In this experiment, optimizing extraction method of mucilage was evaluated based on the Patumi and Karawya methods and comparing the amount of mucilage in jujube ecotypes. For this purpose, 25 ecotypes of jujube were collected from different parts of the country. Research was performed in two separate experiments in a completely randomized design with four replications in the Genetics and Plant Physiology lab of the University of Tehran during 1388 and 1389. Results of this study showed that warm extraction was identified as the most suitable method. Also, results showed that there were significant differences among ecotypes in terms of amount of mucilage. The variation range of mucilage differed among the ecotypes from 28/92% to 11/58%. Maximum amount of mucilage was recorded for ecotypes of Kasva (Qom) and Kolaleh (Mazandaran). Generally, results of this research could be used to select the best ecotypes for medicinal purposes as well as providing good information for linebreeding of the valuable medicinal plant.

This research was performed in order to investigate flowering shoot yield, morphological characters, percentage and yield of essential oil and relationship between characters of two ecotypes of Mentha longifolia var. amphilema L. at Research Institute of Forest and Rangelands for six years in 1999 to 2004. This experiment was conducted as a split plot on time by using of randomized complete block design (RCBD) with three replications. Main and sub factors were ecotypes and years, respectively. The results showed significant differences between leaf oil yields, flower oil yields and flower yields in different ecotypes. There were also significant differences between all evaluated characters (plant height, leaf long, leaf width, stem diameter, lateral shoot, yield of flower, percentage and yield of flower essential oils, leaf yield, percentage and yield of leaf essential oils, yield of flowering shoots and their oils) at 0.01% level of probability in different years. There was significant relationship between total essential oil with yield of flowers and leaves and their essential oils at 0.01%level of probability. There was significant relationship between yield of flowering shoot with leaf long and lateral stem at 0.05% level of probability, and between yield of flowering shoot with leaf yield, essential oil percentage and yield of flower, leaf yield, essential oil percentage and yield of leaf at 0.01% level of probability. The results of stepwise showed that the model compounded of 4 characters: leaf oil yield, flower oil percentage, flower yield and stem diameter. The results of path analysis revealed that leaf oil yield (0.907) had a high direct effect on the dependent (total essential oil yield) variable. So results of path analysis revealed that flower oil percentage (0.019) had a high direct effect on the dependent variable after, yield of leaf essential oil.
