| Abstract: | Based on pot experiment, the authers studied the effect of acid rain on activated oxygen scarenging system of wheat, and the conservation of rare earth elements. The result showed that acid rain could cause decrease of the activities of superoxide dismutase(SOD) and catalase (CAT) and incresed of peroxidase(POD) activity, leading to decreased scarenging ability of the activited oxygen. After treated with rare earth elements, the total level of the activities of SOD and CAT increased, and the increasing rate of the POD activity was much recduced scale. All these could improve the activated oxygen scarenging system in wheat leaves and, consequently alleviated the harmful effect of acid rain. |
