Effect of Lead Stress on the Activity of Antioxidant Enzymes in Wheat Seedling

Pang Xin, Wang Donghong, Peng An (State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco Environmental Sciences, Chinese Academy of Sciences,Beijing 100085, China)  
The changes of the antioxidant enzyme activity, such as superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) were researched through nutrient solution culture. The results showed that the activity of SOD in shoot and root were significantly enhanced under lead stress. The activity of CAT in root was also improved, but the degree was not bigger than that of SOD activity. However, the MDA content in shoot and root was significantly higher than that of check group, it suggested that the membrane system were damaged by lead stress. The experiments also revealed that the shoot of wheat seedling was influenced by lead stress greatly stronger than that of root.
