Abstract: This study discussed the effects of Cd2+、Pb2+ single and their Combined pollution on sprouts, MDA contents and SOD activitis of Casuarina equisetifolia seedlings. The results showed that the seed germination percentage, the height, length of roots, fresh weight, and dry weight of seedlings all obviously decreased with treatments of the increasing Cd2+、Pb2+ single and their Combined pollution concentrations; At the meantime, both the MDA contents and the SOD activity of Casuarina equisetifolia seedlings present increase tendency. Based on all above, Cd2+、Pb2+ single and their combined pollution led to some damage effects on seed germination of Casuarina equisetifolia. The results also suggest there is a cooperative effect of Cd2+and Pb2+ on seed germination,but there is an antagonist effect on membrane lipid oxidation and antioxidants physiological characteristics in a way.
