摘要
GA3与GA4+7采用2种不同浓度,在花前10d、1d和盛花期对巨峰(Kyoho)葡萄进行无核处理,花后10d以GA3和CCPU以3种浓度组配进行膨大处理。各处理都使巨峰葡萄的无核率大幅度提高。用GA3处理比用GA4+7处理更有利于巨峰葡萄产生无核果。GA3花前1d处理对其产生的无核效应明显大于花前10d和盛花期的处理;以花前1dGA312.5mgL-1+盛花后10dGA312.5mgL-1效果最好,其无核率可达90.91%。GA4+7对提高巨峰葡萄的座果效果比较显著,以花前1dGA4+725mgL-1+盛花期GA325mgL-1+CPPU20mgL-1效果比较好,座果为对照的123.1%。在巨峰葡萄上,用GA3进行处理的果实有变长的趋势,而用GA4+7进行处理的则使果实有变圆的趋势。
GA3 and GA4+7 were evaluated at 10-days ,1-day, prebloom and bloom and 2 concentrations for inducing of seedless of Kyoho grape. GA3 and CPPU were treated 10-days postbloom once at 3concentratinos for promoting berry size. Every treatment effectively increased seedless rate of Kyoho grape over control treatment. GA3 had little more effect than GA4+7 on inducing seedless of Kyoho grape. The treatments of 1-day prebloom with GA3 were great increase in seedless rate than of 10-days prebloom. The best treatment for inducing seedless of Kyoho grape was 1-day prebloom 12.5mgL-1 GA3+10-days postbloom 12. 5mgL-1 GA3. The seedless rate was 90.91%. GA4+7 effectively increased grape fruit seat rate. The best treatment was 1-day prebloom 25 mgL-1 GA4+7 +10 day postbloom 25mgL-1 GA3+20 mgL-1 CPPU. The fruit seat rate was increased over control by up to 123.1%. GA3 had the tendency to increase the berry L/D, but GA4+7 to decrease .
