A Preliminary Report on Inducing Seedless'Xinyu'Grape
摘要
Abstract
[Objective] This project aims to study the effects of GA 3and SM on seedlessness and fruit quality of 'Xinyu'grape in the hope of providing reference for the production of seedlessness of 'Xinyu'grape.[Method]The parthenocarpic ability of 'Xinyu'grape was investigated by emasculating treatment.The rela-tionship between seedless rate and fruit quality of 'Xinyu'grape was analyzed by GA 3and SM treatment three days before anthesis and different hormone treatments in flowering stage.The seedless rate and fruit quality were determined.[Result]'Xinyu'grape had the strongest parthenocarpic ability.Getting different degrees of seedless fruits by GA3and SM treatment 3 days before the flowering and in full -bloom stage,obtained seed-less fruit in varying degrees,but the fruit grain weight and fresh fruit hardness were smaller than those of the control(CK).The effect of seedlessness by GA 3and SM combined treatment was better than that by single hormone treatment,cluster seedless rate could reach more than 96%,and fruit quality was better.The stabili-ty of full flowering period was better than that of 3 days before anthesis.There was a significant negative corre-lation between the seedless rate of the spike and the average grain weight and the number of mature days(a=0.01), and there was a significant positive correlation(a =0.05)between the content of soluble solids (TSS).[Conclusion]'Xinyu'grape has the good potential for seedlessness cultivation.In a comprehensive comparison,using 25 mg/L GA3+100 mg/L SM treatment in full-bloom stage,higher seedless rate and bet-ter fruit quality can be obtained.关键词
