The electrolyte leakage,soluble sugar,SOD and MDA in five species of color-leafed ground cover plants were studied.The result showed that cold resistance of these plants had conspicuous difference.Under different cold temperature stresses,the color-leafed ground cover plant with strong cold-resistance showed the higher activity of soluble sugar and SOD and lower MDA content.The concentration of SOD,soluble sugar and the concent of MDA can be used as indexes to judge the ability of cold-resistance.
