春季发生霜害可能性大的地区,调节落叶果树开花的时间是重要的。秋季或春季在花芽膨大之前立即使用植物生长调节剂,已作为调节开花期既手段被提出来。Proebsting和Mills成功地采用乙烯丰延迟了樱桃开花。Webster发现秋季施用乙烯丰推迟李的开花时间3—13天。 据报道,赤霉酸会影响桃的开花期。Corgan和Widmoyer以及Painter和Stembridge的研究发现,秋季施用赤霉酸能阻碍翌年春季花芽的发育。然而,其他研究者却报道,采用乙烯丰和赤霉酸处理,其效果不明显或出现产量显著下降的副作用,故在商业上没有应用价值。本文介绍作者在新泽西州采用乙烯丰和赤霉酸调节‘Cresthaven’桃
It is important to adjust the timing of flowering of deciduous fruit trees in areas where spring frost is most likely to occur. The use of plant growth regulators immediately prior to flower bud enlargement in autumn or spring has been proposed as a means of regulating flowering. Proebsting and Mills successfully adopted vinyl abundance delayed cherry flowering. Webster found that the autumn application of ethylene abundance delayed Lee flowering time 3-13 days. It is reported that gibberellic acid will affect the flowering of peach. Research by Corgan and Widmoyer and Painter and Stembridge found that the application of gibberellic acid in the fall can hinder flower bud development the following spring. However, other researchers have reported that the use of ethylene abundance and gibberellic acid treatment, the effect is not obvious or there is a significant decline in the output side effects, it has no commercial value. This article describes the author of ’Cresthaven’ peach regulated with vinylfen and gibberellic acid in New Jersey
