Abstract
The effects of different concentrations of Cd~(2+)stress on the relative plasma permeability,malondialdehyde(MDA),peroxidase(POD),catalase(CAT) and their isozymes in cumuber leaves were studied by using sand culture.The results showed that Cd~(2+)stress increased plasma permeability and MDA contents,promoted activities of POD and CAT obviously,as well as leaded the larger changes in components of POD and CAT isozymes in cumuber leaves.
