Influence of Drought Stress on Activity of Cell Protective Enzymes in Jujube

Abstract

Abstract: In order to study the effects of drought stress on activity of cell protective enzymes in Jujube, one-year-old Jujube grafting plant have been used as material. The protective enzymes, activities of superoxiede dismutase(SOD), catalse (CAT), peroxidase(POD), the content of MDA and the cell membrane systems of mulberry were studied under different water conditions. The results showed that activity of SOD, POD and CAT in different treatment showed the same tendency of increasing firstly and then decreaseing, which demonstrated activity of cell protective enzymes was increased under drought stress, but with the heavier stress and exceed the endurance degree was then decreased. at the same time, the cell membrane systems of mulberry were damaged and osmotic capability boosted, relative electric conductivity and MDA content increased.
