Abstract:
Lettuce and Chinese cabbage were treated with acid rain (A) and/or deposited coal dust (D) in neutral purple soil and acid purple soil, and the activities of superoxide dismutase (SOD),catalase (CAT) and peroxidase (POD) in the two vegetables were studied. The results indicated that the treatments with A.D and (A +D) could increase the activities oft SOD and CAT in lettuce,and (A+D) treatment raise SOD activity by 11.1% ~21.2% and CAT activity by 15.5%~22.7% in acid purple soil. A.D and (A+D) treatments could also increase the activity of POD in Chinese cabbage, and (A+D) treatment raise POD activity by 50%~52% to neutral purple soil.
