چکیده

physiological effect of five levels of water stress (0,-0.3,-6,-9 and -1.2mp) was studied on seed germination and tigella as well as radicule growth length in two different artemisia species namely: artemisia spicigera and artemisia fragrans. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 50 seeds were sown from each artemisia species. experimental design was a factorial one of complete randomized design. maximum germination rate was obtained at -0.3 mp. germination rate, and tigella & radicule growth lengths declined with decreasing water potential level. artemisia spicigera was more resistant to water stress in comparison with artemisia fragrans.
