The effects of drought stress on growth and development of buckwheat seedling were treated with the osmotic stress solution PEGwere studied using four tartary buckwheat cultivars. The results showed that with the intensification and the time delay of drought,content of chlorophyll decreased gradually,and activities of superoxide dismutase (SOD),peroxi2 dase (POD),catalase (CAT) increased first then decreased,and content of malondialdephyde (MDA) increased gradually. Compared to other three tartary buckwheat cultivars,Xinong 9976 had the higher content of chlorophyll and the activities peak of dismutase (SOD),peroxidase (POD),catalase (CAT),the maximum value of activities was delayed,Xinong 9976 kept up the heigher Activities of protective enzymes and had a lower content of malondialdephyde (MDA).
