以库尔勒香梨[白梨(Pyrus bretschneideri Rehd.)的变种]为材料，在果实生长发育、成熟衰老期间检测内源IAA、GA3、ABA、乙烯含量变化规律及其相互关系。结果表明：果实发育初期IAA、GA3、ABA含量最高，有利于幼果坐果；CA3与ABA的比值变化对果实迅速膨大起关键作用；高浓度GA3对阻抑叶绿素分解起明显作用；果实成熟衰老期间，IAA含量与乙烯释放速率呈方向相同的变化；在此期间GA3含量变化与乙烯释放变化相反。

Changes in endogenous IAA, GA3 and ABA contents and release rate of ethylene of fragrant pear [a variety of bretschneider pear (Pyrus bretschneideri Rehd.)] fruit and the interrelations between 4 kinds of plant hormones were studied during fruit development, ripening and senescence. It was shown that IAA, GA3and ABA contents were highest during the early period of fruit development ( Fig.2), which favored fruit set. The changes in ABA/GA3 rate seemed to be the key factor in determining fruit expansion (Fig.3). High GA3 content obviously inhibited the decomposion of chlorophyll (Fig.2); At the period of fruit maturity, the change in IAA content and the ethylene release rate were along the same direction, the change in GA3 content was negativly correlated with the ethylene release rate (Fig.5).
