Abstract
Effects of Trifolium repens L. seed germination under cadmium(Cd)stress were studied by hydroponic experiment. Results showed that with increasing Cd concentration,the biomass gradually decreased and MDA content increased. Superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)still remained a highly active. When Cd concentration was 10~50 μmol/L,MDA content slightly rose and SOD activity significantly increased. When Cd concentration was 1 250 μmol/L, MDA content significantly increased and SOD activity decreased but still higher than the control. When Cd concentration was 10~ 250 μmol/L,ascorbate peroxidase(APX)kept highly active but it decreased compared with the control under 1 250 μmol/L. Under Cd treatment,SOD,POD and CAT of Trifolium repens L. seed germination worked cooperatively and removed reactive oxygen species(ROS)effectively to keep MDA content in a relatively stable level within a certain scope of Cd. These antioxidant enzymes played important roles in decreasing the membrane lipid peroxidation and enhancing its resistance. At the same time,it showed that Trifolium repens L. has a good application prospect of Cd contaminated soil remediation in the city.
