Abstract:

In this stady, the change in the content of malonaldehyde (MDA) and the activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) in fruit body of Panus giganteus during its development process were investigated. Results indicated that MDA content exhibited a gradual accumulation and the membrane lipid peroxidation was increased; meanwhile, the activities of SOD and CAT exhibited an initial increase and a final decrease trend; the highest activity of SOD and CAT was observed in the cup stage and pin-head stage. However, POD activity was stable during the stage of growth and senescence. Therefore, the metabolic disorder induced by the accumulation of active oxygen species was one of important factors for the senescence of Panus giganteus.

Key words: fruiting body, anti-oxidant enzymes, Panus giganteus, development
