Abstract

Environmental stress is an important factor to reduce agricultural productions. However, stress has a direct impact on the amount of active substances in medicinal plants. So investigation to effect of biotic and non-biotic stresses on yield and active substances of various medicinal plants are very important .In this study the effect of different IRRIGATION levels on some morphological factors and the amount as well as the composition of the ESSENTIAL OIL of lavender were studied. For this project, lavender plants were cultivated in a research greenhouse at International University of Imam Khomeini .The effects of different IRRIGATION levels (20, 40, 60 and 80 % FIELD CAPACITY (FC) were investigated on some morphological factors. ESSENTIAL OILs were obtained by water distillation method (Clevenger apparatus) and were analyzed by GC/MS, while ESSENTIAL OIL yield on completely randomized block design with four treatments and three replications .Analysis of variance showed that the IRRIGATION levels has a significant effect on number of branches per plant (5%), but the plant height, stem diameter and leaf length and width had not significant differences. IRRIGATION levels also had significant effect on ESSENTIAL OIL percentage, ESSENTIAL OIL composition, the amount of chlorophyll and stomata resistance. According to the results of the comparisons, the highest percentage of ESSENTIAL OILs (2.6 percent), the highest amount of chlorophyll (54.73) and the highest value of stomata resistance (12.2) were obtained in 40% FC treatment. The highest α-pinene,β-pinene and α-cadinol content in ESSENTIAL OIL (2.893, 3.759 and 3.658% respectively),were obtained with 40% FIELD CAPACITY treatment, but highest amount of 1,8-cineol and camphor (41.284 and 18.765%),were obtained with 80% FC. The results of this study indicated that IRRIGATION at 40% FC is the best condition for obtaining a plant with high quality and the highest level of ESSENTIAL OIL.
