The effect of different concentrations of aminoethoxyvinylglycine (AVG; 0 (control), 250, 500, 750 and 1000 mg/l), an ethylene biosynthesis inhibitor, on grape berry set and fruit quality was evaluated under vineyard conditions. Treatments were performed on ‘Alphonse Lavallée’ grape cultivar at full bloom stage for two years. Cluster and berry growth (length, width and weight), firmness, soluble solids content, yield, berry set, anthocyanin content and colour parameters were determined on treated and untreated (control) fruits. As a result of the study, the effects of AVG concentrations on firmness were not significant. When AVG applications were compared with control, it is determined that some quality properties were statistically affected, the others were not. Fruit set was increased by lower concentrations of AVG (250 mg/l) and anthocyanin content was increased by higher concentrations of AVG (750 mg/l).

氨基乙氧基乙烯基甘氨酸 (AVG) 对‘Alphonse Lavallée’鲜食葡萄品质、果实结节和着色的影响

在葡萄园条件下，评估了不同浓度的乙烯生物合成抑制剂氨基乙氧基乙烯基甘氨酸（AVG；0（对照）、250、500、750 和 1000 mg/l）对葡萄果实坐果和果实品质的影响。在盛花期对'Alphonse Lavallée'葡萄品种进行了两年的处理。测定处理和未处理（对照）果实的簇和浆果生长（长度、宽度和重量）、硬度、可溶性固形物含量、产量、浆果集、花青素含量和颜色参数。研究结果表明，AVG 浓度对硬度的影响并不显着。当将 AVG 应用程序与对照进行比较时，可以确定某些质量属性受到统计影响，而其他则没有。
