Polyethylene glycol (PEG) was used to provide appropriate water potentials. A total of 100 seeds in four replications (Petri dishes) were sown from each species. Experimental design was a factorial one of complete randomized design. Maximum germination rate was obtained at 0 MP. Germination rate and plumule and radicule growth declined with water potential level. The most resistance species to water stress are Secale montanum, Agropyron elongatum and Agropyron desertorum respectively.
