10% S-诱抗素可溶性粉剂对葡萄产量及品质的影响

目的研究10%S-诱抗素可溶性粉剂对葡萄产量及品质的影响。方法选用10%S-诱抗素可溶性粉剂为实验药剂、0.01%芸苔素内酯可溶液剂为对照药剂,设置5个浓度在葡萄绒球期灌根,处理7、15、25d后测量葡萄生长指标,果实成熟后测定产量和品质指标。结果10%S-诱抗素可溶性粉剂对葡萄芽纵径、横径、果粒直径均有促进作用,并显著提高产量和品质。与清水对照相比,10%S-诱抗素2500倍液灌根后7 d对葡萄芽生长促进效果最好,纵径和横径促进率分别为34.23%和26.16%;施用2500倍液增产效果最好,果粒重和果穗重增长率分别为6.38%和30.01%。果实品质检测结果表明,施用10%S-诱抗素可显著提高葡萄可溶性固形物、含糖量、可滴定酸和原花青素含量。结论10%S-诱抗素可溶性粉剂可有效提高产量并改善葡萄品质。

Effect of 10% abscisic acid soluble powder on yield and quality of grape

In order to study the effect of 10% Abscisic Acid soluble powder on grape fruit growth and quality, and to guide the rational application of this agent in grape production, 0.01% brassinolactone soluable water aqua was used as the control treatment. Five concentrations were set for root filling treatment in grape pomelo stage.The results showed that the Abscisic Acid had significant effect on increasing grape yield and the content of sugar, procyanidins and vitamin C in the fruit.
