摘要：
Activities of superoxide dismutase (SOD), guaiacol peroxidase (PX), glutahione peroxidase (GPX) and catalase (CAT) as well as formation of malondialdehyde (MDA) and liposoluble fluorescent compounds (LFC) in leaves of 20 wheat genotypes, parents and hybrids of F1 and F2 generation were examined. The aim was to determine inheriting pattern of investigated parameters and relation between antioxidative enzyme activities and lipid peroxidation and LFC formation. No consistent role of inheritance of antioxidant parameters was found. Investigated genotypes and hybrids, among themselves, differed significantly in antioxidative enzyme activities and MDA and LFC content. Results presented indicate that high contents of MDA and LFC are associated with low activities of antioxidative enzymes. Also, relatively small quantities of MDA and LFC are associated with high activities of SOD and CAT.
