摘要/Abstract

摘要： 采用酶联免疫法( ELISA) 分析了巨峰葡萄2年生自然实生树不同节位芽中内源赤霉素(GA₃
和GA_{4 + 7} ) 、吲哚乙酸( IAA) 、脱落酸(ABA) 、玉米素核苷(ZR) 和异戊基腺嘌呤( iPA) 的含量; 并对实生树自然条件下最低成花节位进行了调查。结果表明, 2年生巨峰实生树在20节左右进入生殖生长阶段, GA₃和GA_{4 + 7}的含量随着节位升高而降低, ABA的含量却急剧增加, 但在第31～35节又降到很低;ABA /GA₃和ABA /GA_{4 + 7}在16～20 节前变化不大, 而在此之后, 都一致表现出上升的趋势, 这反映了以GA₃或GA_{4 + 7}为基数的比值, 可以更明显地反应激素的变化及其与巨峰葡萄阶段转变的关系。

Abstract: The contents of endogenous hormones ( including GA₃ , GA_{4 + 7} , IAA, ABA, ZR and iPA) were analyzed with the method of EL ISA in different buds which located different nodes of two-year-old Kyoho grape seedings, and the lowest inflorescence nodes were investigated. The results revealed that the reproductive phase appeared at about 20th node. The contents of GA₃ and GA_{4 + 7} decreased, the ABA content increased sharply during the process of phase change, but the content of ABA was so low that itwas hardly been detected at the nodes 31 - 35th ; the ratio of ABA /GA₃ and ABA /GA_{4 + 7} varied slightly at the nodes 16 - 20th , but after that rose obviously. So we concluded that the ratio obviously reflected the relationship between variations of hormones contents and phase change than simplex variations of hormones contents.
