Abstract: The cell membrane permeability, MDA content and POD act-ivity in leaves of two soybean varieties different in resistance to salt were studied under salt stress, using the solution culture method. It was found that with increase of salt concentration the damage to the plant became serious, the cell membrane permeability increased, the relative water content decreased. MDA content went up, lipid peroxidation reaction sharpened, and the POD activity strengthened. In the salt-resistant soybean varieties, on the contrary, the lipid peroxidation reaction level was lower, but the POD activity was higher. These facts indicated that the lipid peroxidation of cell membrane was one of reasons causing the soybean plant injury by the salt strees. The higher le al POD activity could reduce the injury degree.

Key words: Soybean, Salts ess, Lipid peroxidation
