为探讨黄瓜植株性别表现与保护酶活性的关系,以雌性系和雌雄同株系黄瓜为试材,测定二片真叶期植株茎尖和真叶的过氧化物酶、过氧化氢酶和超氧化物歧化酶的活性.结果发现:黄瓜植株茎尖中保护酶活性与性型关系密切,过氧化物酶活性在雌性系中较高,而在雌雄同株系中则较低.过氧化氢酶和超氧化物歧化酶的活性在雌性系中较低,在雌雄同株系中较高;真叶中保护酶类活性性型间不表现出差异或者差异不显著.

To explore the relationship between activities of protective enzymes and sex expression of cucumber(Cucumis sativus)plants,the activities of peroxidase(POD), catalase(CAT) and superoxide dismutase (SOD) in gynoecious plants and monoecious plants were determined.The results show that the activities of POD in the shoot tips of gynoecious plants are higher than those in monoecious plants;the activities of CAT and SOD in the shoot tips of gynoecious plants are lower than those in monoecious plants.In the leaves, the activities of protec...
