摘　　要：以7a生"大金星"山楂为试材,研究了花期喷布不同浓度赤霉酸和芸苔素内酯对山楂坐果率、果实大小、着色和耐贮性的影响。结果表明:山楂在花期喷赤霉酸能显著提高山楂的坐果率、增大果个、促进果实着色,但果实硬度明显下降,不耐贮藏;喷芸苔素内酯的山楂其坐果率、果个、着色和耐贮性都好于对照;对长期贮藏的山楂用0.04%的芸苔素内酯来代替赤霉酸,能显著提高山楂的耐贮性。Abstract：Taking 7-year-old ＇Dajinxing~ hawthorn as material,the effect of spraying different concentrations of gibberellic acid and brassinclide in florescence on the fruit-setting rate, size,coloring and storability of hawthorn were studied. The results showed that after using gibberellic acid in florescence of hawthorn, the fruit-setting rate, size and colorings significantly increased, but the hardness decreased that it go against storage. However,by spraying brassinolide, the fruitsetting rate,size,colorings and storability were better than control group. Compared gibberellic acid,0. 04% brassinolide could improve storability significantly for long-term storied hawthorn.
