Ethrel applied flower buds had a lower growth rate than the controls, as indicated by bud length, width and dry weight.Applide flower buds also had smaller styles, shorter filaments and smaller ovaries than the controls. At full bloom the style lengths of the ethrel-applied and control flower buds were about 6.42 and 9.26mm, while filament langths were about 4.00 and 5.06mm, respectively. The style length, ovary weight and filament lengths of applied flower buds were 80.0%, 83.2% and 82.9% of that of the control. The changes in 4 kinds of endogenous plant hormones levels (GAs, cytokinin and ABA) , carbohydrates contents (sugar and starch) and nitrogenous compounds contents (amino acid and protein) during the dormant period in one year old shoot were not related to ethephone application. The fall ethephon application was a greater bloom delay effect in 'Inazumi' than 'Shirokaga'.The activity of AC-94,377 to promote parthenocarpic fruit growth enhanced with the auxin application by inhibiting fruit abscission. Among kinds of tested auxin, 10ppm of 2,4-DP,20ppm of 2,4-D and 50ppm of NAA,IPA and MCPB showed higher efficiency on increase percent fruit set when compared with natural pollination.By pre-harvest method to control fruit ripening, 0.1mM of MGBG and 0.1mM of AOA applied to fruit at 20 to 30 days before normal harvest date have been shown to delay fruit ripening on tree. 0.1mM,1mM or 10mM of MGBG and 50ppm, 100ppm or 200ppm of AVG applied by post-harvest methode were effevtive to prolong the storage life of Japanese apricot fruit.

从芽长、宽度和干重来看，施用乙烯利的花芽的生长速度比对照低。与对照相比，施用乙烯利的花芽还具有较小的花柱、较短的花丝和较小的子房。在盛开时，应用乙烯利的花蕾和对照花蕾的花柱长度分别为约6.42和9.26毫米，而花丝长度分别为约4.00和5.06毫米。施用花蕾的花柱长度、子房重量和花丝长度分别为对照的80.0%、83.2%和82.9%。一岁芽休眠期4种内源植物激素水平（GAs、细胞分裂素和ABA）、碳水化合物含量（糖和淀粉）和含氮化合物含量（氨基酸和蛋白质）的变化与施用乙烯酮无关。秋季施用乙烯利对'Inazumi'的花期延迟效果比'Shirokaga'更大。施用生长素可抑制果实脱落，从而增强AC-94,377促进单性结实果实生长的活性。在受试植物生长素中，与自然授粉相比，10ppm的2,4-DP、20ppm的2,4-D和50ppm的NAA、IPA和MCPB在增加坐果率方面表现出更高的效率。通过采前控制果实成熟的方法，在正常采收前20至30天向果实施用0.1mM MGBG和0.1mM AOA已被证明可以延迟果实成熟。在树上。采后施用0.1mM、1mM或10mM的MGBG和50ppm、100ppm或200ppm的AVG可有效延长杏果实的贮藏期。
