Abstract

This study was done on four range species of AGROPYRON DESERTROUM, BROMUS INERMIS, Lotium prenne, SEEALE MONTANUM in order to evaluate the effect of the grooming of OSMOPRIMING on the tolerance against DRY STRESS in the seeds of the plants. This study was done in the face of the factorial experiments in the form of the complete random block in 3 repeats and 3 steps of the experiment. By the use of the solution of the polyethylene glycol (PEG) in the levels of -8 , -12 , -16 bar , the load of DRY STRESS was calculated on the primed seeds (The best level of the prime was -8 bar for all of the seeds and the best time was 48 hours for AGROPYRON DESERTROUM and Lotium prenne, and the best time was 24 hours for BROMUS INERMIS and SEEALE MONTANUM)and the non-primed seeds and the percent and the speed of the germination and the length and the dry weight of the rootlet and the plumule and then was compared with the control. The mutual effects for the plants and the prime and also the dryness, the prime and the plant and dryness in the level of the probability of 0.01 were meaningful. Each of the abovementioned pastoral plants had the highest percent and the speed of the germination in the level of zero (control) and the lows percent and the speed of the germination in the dry level in -16. Also, the percent and the speed of the germination of each plant were observed in the primed level higher than the non-primed level.
