| 摘 要： | Reports the effects of selenium on lipid peroxidation of soybean under continuous cropping stress,Results of pot culture and plot experiment showed that appropriate amount of Se addition increased the activity of glutathione peroxidase (GSH-Px) significantly,and cleared away the excessive free radicals existing in soybean plant under continuous cropping stress,decreased the concentration of malonaldehyde(MDA),which is the end product of lipid peroxidation,maintained the perfection of chlorophast and mitochondrion structure,enhanced the resistance of continuous cropped soybean,and therefroe increased the dry weight of seedlong and yield.
