摘　要：

以9年生富士苹果为材料, 研究富士苹果形成过程中BA、GA₃和IAA对果形、品质、内源激素含量的影响。结果表明: 在花期喷GA₃对富士苹果的坐果率影响效果最好, 分别比清水对照和无处理对照提高49%和79.45%。BA 100 mg·L^-1-+GA₃ 300 mg·L^-1+IAA 20 mg·L^-1对降低富士苹果偏斜率效果最好。在花期、花期+幼果期和幼果期分别喷BA和在花期喷GA3可以提高果实中可溶性固形物的含量。花期喷IAA、BA、GA₃和BA+GA₃+IAA对内源激素IAA和GA₃的含量均有促进作用, 在整个生长季内不同处理下IAA、GA3含量均高于清水对照且差异明显; 花期喷BA、GA3和BA+GA₃+IAA对内源激素ZT含量有促进作用, 尤其在果实幼果期和膨大期与清水对照相比效果明显; 花期喷GA₃和BA+GA₃+IAA与清水对照相比内源激素ABA含量有明显降低, 其中幼果期变化显著。

Abstract:

The Fuji Apple about 9-year-old was selected as research object to reveal the effect of BA, GA₃ and IAA on fruit shape, quality and endogenous hormone during the formation process. The results showed that spraying GA₃ at blossom had the best effect on fruit setting rate which improved higher 49% than that under water treatment and higher 79.45% than that under no treatment, respectively. Spraying BA 100 mg·L^-1+IAA 20 mg·L^-1+GA₃ 300 mg·L^-1 had the best effect to reducing in the deviation index. Spraying BA at blossom, blossom + young fruit and young fruit, and GA₃ at blossom can increase the contents of soluble solids. Spraying IAA, BA, GA₃, and BA+GA₃+IAA had improving effect on endogenous hormones IAA and GA₃ contents at blossom stage. Whereas the contents of IAA and GA3 in fruit trees under different measurements differed significantly and higher than that of the contrasts in the whole growing season. Spraying BA, GA₃, BA+GA₃+IAA has im-proving effect on the content of endogenous hormone ZT, especially at young and enlargement periods. Spray-ing GA₃, BA+GA₃+IAA in young fruit period, ABA content compared with the contrast, significantly decreases.
