Abstract： 采用酶联免疫分析法(ELISA)提取和测定米槠和格氏栲发育过程中果实内ABA含量,并用不同浓度ABA喂养,测定果实不同发育期对外源ABA的敏感性.用放射性同位素法测定ABA对贮藏蛋白质的积累作用,结果表明:在米槠和格氏栲种子发育过程中内源ABA含量逐渐上升,两者均在10月5日达到峰值,米槠为1 648 ng/g,格氏栲为1 468 ng/g,随后ABA含量均逐渐下降.果实成熟采收时, c(ABA)仅为高峰时的1/9.随着果实的发育对外加ABA的敏感性逐渐变小,c(ABA)=10-4 mol L-1可以完全抑制10月25日(米槠)和10月15日(格氏栲)前种子发芽,但对完全成熟的种子c(ABA)=10-2 mol L-1亦不能抑制发芽.ABA对成熟前期胚的贮藏蛋白质合成无影响,但能促进成熟中后期胚的贮藏蛋白质的积累作用,ABA维持米槠和格氏栲贮藏蛋白质合成和积累作用表现在转录水平上.
