摘要

花生胚发育过程中，子叶和胚轴中都出现BAPAase活性。花生种子萌发时，子叶和胚轴中的BAPAase活性迅速上升，子叶中无新的BAPAase合成，胚轴中能重新合成BAPAase。ABA抑制了子叶和胚轴中BAPAase的活性，抑制胚轴中BAPAase活性所需的外源ABA浓度更高， Act-D和CHM不能逆转ABA对BAPAase活性的抑制作用。

Abstract

During the development of peanut (Arachis hypogaea L.) embryos,activity of BAPAase was found in the cotyledon and hypocotyl. When peanut seed were in the process of germination, activity of BAPAase in the cotyledon and hypocotyl increased significantly. Exogenous ABA inhibited the activity of BAPAase in the cotyledon and hypocotyl of peanut seed developing or germinating　in vitro, and concentration of ABA needed was higher in the hypocotyl. Act-D and CHM showed no effect on the action of ABA on the activity of BAPAase of the cotyledon of peanut seed, but they　inhibited obviously the activity of BAPAase of the hypocotyl of peanut, these results indicated that no nevo-BAPAase was synthesized in the cotyledon, but nevo BAPAase was probably synthesized　in the hypocotyl of peanut seed.
