| Abstract: | This paper researched the effect of HgCl2 on membrane lipid peroxidation,permeability of plasma membrane, activities of protective enzymes, superoxide dismutase(SOD),catalase (CAT) and peroxidase (POD), content of soluble protein of maizeseedlings during germination.The results showed that with the increase of concentrationof pretreatment HgCl2, malondialdehyde (MDA) content, permeability of plasma membrane,activities of SOD and POD,contents of soluble protein increased,while activity ofCAT decreased. |
