【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。更多还原

【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 fruit-setting 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.更多还原
