摘要：
Copper nutrition inhibited lipid peroxidation in root nodules of yellow lupin plants at the early growth stages by about 50 %. The antioxidative activity of copper in the process of lipid peroxidation could be associated with Cu taking part in oxidative reaction of nodule calechol-like siderophores and its effect on iron accumulation and reactivity. The obtained results, for the first time, suggest that the ability of copper to inhibit lipid peroxidation in nodules could be considered as a major function for Cu requirements by symbiotic N-2 fixation in grain legume nodules.
