对桃树采用 CGA—15281处理,可以延迟盛花期4～9天,对树体无危害.延迟花期的效果与使用浓度呈相关;秋季使用500ppm 乙烯利处理,可延迟盛花期10～18天,但,对树体有严重危害。125ppm 和250ppm 乙烯利延迟盛花期3～5天,树体发生轻微危害。用乙烯发生物处理结果,延长休眠,减缓花芽发育,而延迟花期。1983年1月,使用 Daminozide 处理,延迟了花期,但,1984年使用则无效。无论何时使用硝酸银,对延迟花期或减少开花密度的效果都是比较小的。在夏末,施用 Dimet-hipin 和 merphos 引起落叶,减少花量,而不影响花期。Thidiazuron 不引起落叶,也不延迟花期,但严重地减少花量。
Peach treated with CGA-15281 can delay flowering period of 4 to 9 days, no harm to the tree.The effect of delayed flowering is related to the use concentration; the use of 500ppm ethephon in autumn can delay the flowering period of 10 to 18 days, However, there is a serious hazard to the tree. 125ppm and 250ppm ethephon delayed florescence 3 to 5 days, the tree minor damage occurred. With ethylene treatment results, prolonged dormancy, slow flower bud development, and delayed flowering. In January 1983, treatment with Daminozide delayed flowering, but was not effective in 1984. Whenever silver nitrate is used, the effect of late bloom or reduced flowering density is relatively small. In the late summer, the use of Dimet-hipin and merphos caused deciduous leaves, reducing flowering without affecting flowering. Thidiazuron does not cause deciduous leaves and does not delay flowering but severely reduces flowering.
