Abstract
To study the effects of NaCl stress of wheat on its physiological and biochemical characteristics,Lanhei wheat and Xiaoyan 15 were taken as tested materials. The superoxide dismutase(SOD) activity,peroxidase(POD) activity, MDA content, relative conductivity, the proline content and the soluble protein content were investigated after different treatments. The results showed that under NaCl stress, compared with the each control, the activities of SOD and POD of Lanhei showed the trend of from increasing to decreasing, while the Xiaoyan15 showed the decreased; MDA content, relative conductivity, the proline content increased significantly as the stress decreased; whereas the trend of soluble protein was different between the 2 cultivars. Both of them had resistance to salt, and Lanhei wheat was a relatively higher salttolerant wheat.
