摘　　要：采用 5种不同浓度的PBO溶液 ,在新梢进入迅速生长期的前期对凯特杏进行叶面喷施 ,研究PBO对凯特杏新梢生长的影响。结果表明 :PBO浓度越高 ,控梢效果越明显 ,但是高浓度PBO( 2 5 0mg/L)对凯特杏的作用效果不明显 ,因此 ,选择浓度为 5 0～2 0 0mg/L的PBO溶液对凯特杏进行叶面喷施 ,控梢效果为佳。Five Concentrations of PBO (50,100,150,200,250*!mg/L) were sprayed on the surface of the Katy apricot just before the shoot turned into rapid growing period.The result showed that the higher concentration of PBO was, the more obvious effect was.But highest one(250 mg/L) had a obsolete effectiveness on Katy apricot's new tip. PBO solution of 50～200 mg/L sprayed on Katy apricot's leaf was more sensible.
