Sweet Basil (Ocimum basilicum L.) is one of the most popular medicinal plants that containing essential oil. Essential oil of this plant has been utilized extensively in the food, pharmaceutical and cosmetics industries. In this study, a pot experiment was conducted to evaluate the effect of biological fertilizers of biosulfur, nitroxin and super absorbent polymer and their interactions on the growth and essential oil content of sweet basil (Ocimum basilicum L.) in the randomized complete block design (RCBD). Aerial parts of plants were harvested at full bloom and evaluated their yield index. All material were air-dried in the shade and subjected to hydrodistillation by Clevenger type apparatus. The results of this study showed that there was a significant difference among the treatments in terms of dry herbage weight at 1% level. The highest yield was obtained in (biosulfur+nitroxin+super absorbent). There was no significant difference in essential oil content according to v/w, but there was the significant difference between treatments in terms of w/w. The highest oil content (w/w) was observed in biosulfur+nitroxin treatment. These differences are probably due to variation in the constituents and specific gravity of the oils.

Abstract
Angelica archangelica, Tanacetum cinerariaefolium and Chelidonium majus are valuable medicinal plants for which there is no comprehensive information about their seed germination in review of literatures. With regarding of the importance of simple propagation of medicinal plants and the role of seed in production of these plants, this study was set out in order to analyzing of the effects of cold stratification (control, 2, 3 and 4 weeks) and acid gibberellic (control, 100, 150, 250, 350, 450, 500 and 1000 ppm) treatments on seed germination of these species. Treatments were arranged seperately in a Completely Randomized Design with 3 replicates. The results showed that the highest mean germination (percentage and rate) was observed in 3 and 4 weeks (40%) and 4 weeks (1.8 seeds per day) cold stratification for Angelica archangelica seeds, 3 weeks (42.67%) and 4 weeks (6.17 seeds per day) cold stratification for Tanacetum cinerariaefolium seeds, and 100 and 350 ppm (100%) and 500 ppm (5.22 seeds per day) GA3 solutions for Chelidonium majus seeds.

Abstract
There is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. One possible alternative is allelopathy. A laboratory trial was carried out to investigate of alleopathic potential of Angelica . In this study the effect of different concentrations of aqueous extract of Angelica herb was investigated on seed germination percentage and rate of Upland Cress (Lepidium sativum) and Radish (Raphanus sativus L.). The trial was carried out in completely randomized design with four replicates. Seven treatments (aqueous extract including 10, 20, 30, 50, 70, 100% and distilled water as a control treatment) were applied on Upland Cress seeds and five treatments (water extract including 30, 50, 70, 100% and distilled water as control) were applied on Radish seeds. The results revealed that treatment of Upland Cress seeds with 50, 70 and 100% aqueous extract significantly decreased percent and rate of seed germination. In Radish, treatment of seeds with 70 and 100% aqueous extract resulted in the least percent of seed germination and treatment of seeds with 50, 70 and 100% aqueous extract resulted in the least rate of seed germination. Overall results showed that with increasing the applied extract concentration, seed germination percentage and rate significantly decreased.

Abstract
In order to study the effect of sowing date and seeding rate on essential oil content and composition of chamomile (Matricaria recutita L.) CV. Presov, prepared from Slovakia, an experiment was conducted. The experimental design was split-plot in the basic of randomized complete blocked design (RCBD) with three replications. Main plots consisted of three sowing dates (6 Nov, 5 Mar, and 4 Apr) and sub-plots included three seeding levels (0.2, 0.4 and 0.8 g/m2). Evaluated traits were essential oil content and percent of -farnesene, -bisabolol oxide B, -bisabolol, chamazulene, -bisabolol oxide A. The results showed that spring sowing (Mar and Apr) produced chamomile with high level of essential oil content. On the basis of the results, the highest essential oil content (0.63 w/w percent) was obtained from the plots were sown on 5 of Mar with 0.4 g/m2 but the highest -bisabolol and chamazulene content (75.99 and 17.31 percent respectively) were obtained from the plots were sown on 4 of Apr with 0.2 and 0.4 g/m2. According to the results, because of high percent of essential oil and desirable content of -bisabolol and chamazulene, the most suitable sowing date and seeding level in Mashhad condition is 5 of Mar with 0.4 g/m2 seeds respectively.

Abstract
This experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (Rosa canina L.) seeds collected from five regions including: Semirom (Isfahan Province), Kiar and Gerdbishe (Charmahal and Bakhtiari Province), Yasuj and Meymand (Kohgiluye and Boyer Ahmad Province). Oil was extracted using Soxhlet apparatus; the fatty acid composition of oil was characterized and quantified using GC. The highest and lowest oil percentage obtained from Meymand (11.05%) and Kiar (8.15%), respectively. The results confirmed the presence of five dominant fatty acids in seeds of dog rose, including: linoleic, oleic, linolenic, palmitic and stearic acid, respectively. Results showed that differences between fatty acids quantity in regions under study was significant (P
