Abstract

Evaluation of MEDICINAL PLANTs to DROUGHT and salt stress tolerance, in an attempt to plant them under DROUGHT and saline regions, is of utmost importance. Environmental stresses, especially DROUGHT and salt, reduce the global crop yields more than other factors. Selection of DROUGHT tolerant crops at GERMINATION stage, usually is, the fast and low cost method. In order to study the effect of osmotic stress on GERMINATION indices of black cumin and milk thistle, an experiment carried out in a completely randomized design with four replications at the Seed Technology Laboratoary of Yasouj University in 2008. Treatments were 0 (as control), -2.4, -4.8, -7.2 and -9.4 bar osmotic potentials created by using PEG 6000. Results showed that, decreasing of osmotic potential reduced speed of GERMINATION and its percentage, root and shoot lengths and dry matter in these two plants. Black cumin showed higher tolerance, to -4.8 bar osmotic potential, as compared to milk thistle. However, milk thistle showed higher tolerance to DROUGHT stress, up to this osmotic potential (-4.8 bar), compared to black cumin. Milk thistle had lower GERMINATION speed and percentage at higher DROUGHT stress as compared to black cumin. Generally, milk thistle showed better growth and survival than black cumin due to its higher root and shoot length and dry matter.
