Abstract
The varieties Shanghaiqing and Wuyueman were planted in hydroponic solution with different contents of copper.The results showed that the activities of superoxide dismutase (SOD) and catalase(CAT) were inhibited under copper stress,on the contrary the activity of peroxidase!(POD) and the content of malondialdehyde(MDA) increased.Cell membrane integrity was spoiled and cell membrane leakage was enhanced.The decline of the value of SOD activity/MDA content value accounted for the decline of self-adjustment of the plant under copper stress.As an important osmoregulation material,free proline in leaves significantly increased with copper concentration of the solution.
