摘要： 对3个中晚熟品种进行不同浓度PP333处理，每品种设每株叶面喷施PP3338000mg/L、10000 mg/L、12000 mg/L和喷清水对照4个处理，单株为一小区，重复3次，随机区组设计，处理1分 2次喷，第一次在5月9日，第二次在6月9日，其余在5月9日喷1次。研究表明，PP333能极显著地抑制枝梢生长。从控制枝梢生长、产量提高、果实形状及圆整度、花芽形成等综合性状分析，4年生大团蜜露以每株喷PP33312000 mg/L、5年生湖景蜜露和6年生西浦1号以每株PP3338000 mg/L喷2次的处理效果最好。

Abstract: Effects of PP333 on growth of shoots of ‘Datuanmilu’, ‘Hujingmilu’ and ‘Xipu No.1’ trees were studied. The study showed that the growth of shoot of medium-late melting peaches was significantly restrained by different concentrations of PP333. From results of shoots growth, yield, and the shape of the fruits, the best concentrations are the 12000 mg/L of PP333 for foru-year-old ‘Datuanmilu’ and 8000 mg/L for five-year-old ‘Hujingmilu’ and six-year-old ‘Xipu No.1’.
