摘　　要：本文以大濑户葡萄品种为材料,在不同时期用不同浓度赤霉素(GA3)和吡效隆(CPPU)处理,研究对其果实发育的影响。结果表明,各处理都使大濑户葡萄的无核率大幅度提高。其中以花前1天GA37.5mg/L处理的无核率最高,达100%,而花前1天GA312.5mg/L处理的无核率达93.8%,果实生长发育效果较好,单果最重达9.61g。Effects of different concentration of GA3 and CPPU treatments at different stage on the seedlessness of Seto Giants grape were studied. The results showed that the seedlessness rate of Seto Giants grape was significantly increased. The grape treated by 7.5mg/ L GA3 one day before flowering had the highest seedlessness rate of 100%. The seedlessness rate of treatment with 12.5mg/L GA3 one day before flowering was 93.8% and the biggest weight reached 9.61g per berry.
