摘要: 对‘苹果梨’花芽分化各时期叶片中过氧化物酶(POD) 、吲哚乙酸(IAA) 氧化酶、蔗糖酶和过氧化氢酶(CAT) 活性进行研究, 前三者在花芽分化临界期(7月23日) 达高值, 而后者处于低值; 在花蕾、花萼分化期CAT 活性增强, 蔗糖酶、IAA 氧化酶、POD 活性降低; 花瓣、雄蕊、雌蕊分化期POD、IAA 氧化酶活性增加, 蔗糖酶变化不大, CAT降至最低。

Abstract: The change of peroxidases (POD) , catalase (CAT) , IAAoxidase and sucrase activity in leaves during flower bud differentiation of “Pingguoli”was studied. The results showed that POD , IAAoxidase and sucrase activity
were high , but CAT activity was low in the critical period of flower bud differentiation (23 , July) . CAT activity increased , sucrase activity decreased and IAAoxidase , POD activity decreased little during alabastrum , calyx differentiation. POD , IAAoxidase activity gradually increased , sucrase activity didn’t change significantly , CAT activity declined to the lowest during petal , stamen , pistil differentiation.
