中文摘要:

      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、25 d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。

英文摘要:

      Objective To study the effect of 10% abscisic acid soluble powder on yield and quality of grape. Methods The 10% S-abscisic acid soluble powder was used as experimental agent and 0.01% brassinolide solution was used as control agent. Five concentrations were set for root irrigation at grape pompous stage. The grape growth indexes were measured after 7, 15 and 25 d of treatment, and the yield and quality indexes were measured after fruit ripening. Results The 10% S-abscisic acid soluble powder promoted the longitudinal diameter, transverse diameter and fruit grain diameter of grape buds, and significantly improved the yield and quality. Compared with the control with clear water, 2500 times liquid of 10% S-abscisic acid antigens had the best effect on grape bud growth 7 d after root irrigation with 10% S-abscisic acid antigens, and the promotion rates of longitudinal and transverse diameters were 34.23% and 26.16%, respectively. The yield increase was best when 2500 times liquid was applied, the growth rates of grain weight and ear weight were 6.38% and 30.01%, respectively. The fruit quality test results showed that the soluble solid, sugar content, titratable acid and proanthocyanidin content of grape could be significantly increased by applying 10% S-induced antibody. Conclusion The 10% abscisic acid soluble powder can effectively increase yield and improve grape quality.
