摘  要：
研究猪肚菇子实体不同发育时期膜脂过氧化产物丙二醛(MDA)含量、超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性变化情况。结果表明:随着猪肚菇子实体生长和衰老,子实体中MDA逐渐积累,膜脂过氧化程度加重;SOD和CAT活性先升高后降低,SOD、CAT活性最高值分别出现在杯形期和钉头期,而POD活性则基本稳定。因此,活性氧代谢失调引发的生物膜结构破坏是猪肚菇子实体衰老的重要原因之一。

摘  要：
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.
