GA3和CPPU处理对'津郁'葡萄无核化和果实品质的影响
Effects of GA3 and CPPU Treatment on Seedlessness and Fruit Quality of'Jinyu'Grapes
摘要
Abstract
Using'Jinyu'grapes as material,to investigate the effect of gibberellin(GA3)on inflorescence lengthening,and the effects of GA3 and chlorpyriuren(CPPU)on its seedlessness and fruit quality.The results showed that the longest cluster of fruit was obtained by spraying 6 mg·L-1 GA3 in inflorescence at 5-6 leaves(15 d before flowering).All treatments had different effects on grape seedlessness and fruit quality,among the treatment with 25.0 mg·L-1 GA3+2.5 mg·L-1 CPPU dipping cluster at three days after flowering,and 25.0 mg·L-1 GA3+5.0 mg·L-1 CPPU dipping cluster again at fifteen days after flowering had the highest seedless rate.From the comprehensive characteristics of fruits,each treatment was better than the control,among the treatment of 25.0 mg·L-1 GA3 dipping cluster at three days after flowering,and 50.0 mg·L-1 GA3+5.0 mg·L-1 CPPU dipping cluster at fifteen days after flowering had the best effect,appeared that berries were compact and uniform.This experiment can provide reference for the high-quality production of'Jinyu'grapes.关键词
