| 摘 要： | 利用间接酶联免疫（ELISA）检测技术，测定了亚麻雄性不育系及可育系花蕾不同发育阶段生长素（IAA）、脱落酸(ABA)、玉米素核苷(ZR)以及赤霉素(GA3)等4种内源激素含量的动态变化，分析了两者间4种内源激素的平衡关系。结果表明：1）在花蕾的整个发育时期，不育系和可育系4种内源激素含量变化趋势差异明显，且含量高低明显不同。结果表明IAA和GA3含量的降低及ABA和ZR含量的提高可能与亚麻雄性不育的发生密切相关。2) IAA/ABA、IAA/ZR、IAA/GA3和GA3/ABA在两者间的变化趋势不一致，且大小差异很大。表明4种内源激素之间平衡关系受到破坏可能会影响到植物的正常生长发育。

| Abstract: | The changes of the contents of IAA,ABA,ZR,GA3 were measured by ELISA(enzyme-linked immunosorbent assay) and analysis the banlanced relation of four endogenous phytohormones in various bud development stages of male sterility line and its normal variety in Flax. The results showed that: 1) In male sterility line and its normal variety,the discrepancy of the change tendency of the phytohormones contents was obvious during the whole process of bud development stages, and the contents of them were clearly different. It indicated that the reduce of the contents of IAA and GA3 and the heighten of the contents of ABA and ZR are associated with the occurrence of male-sterility. 2) The change tendency of IAA/ABA、IAA/ZR、IAA/GA3、GA3/ABA are inconsistent ;and the discrepancy of them is far obviously. It indicated that the breaks of the equilibrium relationship of these four endogenous phytohormo- nes mighr affected the plant normal growth. |
