摘　　要：脱落酸(ABA)能够调控葡萄果实发育与品质形成,但不同葡萄品种对不同浓度ABA处理的响应差异目前尚未见报道。以酿酒品种赤霞珠、鲜食品种巨玫瑰和户太8号为试验材料,研究了喷施不同浓度ABA对不同葡萄品种果实品质发育的差异。结果表明:在葡萄果实转色期施用ABA,对3个品种的果实品质均具有改善作用,其中赤霞珠果实对100 mg/L ABA处理响应效果最佳,其还原糖、总酚和单宁含量均显著上升;而400 mg/L ABA处理后,巨玫瑰和户太8号的各品质指标上升效果最为明显,总花色苷含量分别升高为对照的5.0、6.8倍。综合来看,脱落酸对于葡萄果实外观和内在品质均具有调控效果,但不同品种对于不同浓度ABA处理的响应存在差异;100 mg/L ABA处理对于提升酿酒品种赤霞珠果实品质的效果最好,400 mg/L ABA处理则更适用于鲜食品种巨玫瑰和户太8号。Abscisic acid(ABA)can regulate the development of grape berries and quality formation,but the responses of grape varieties to ABA concentrations have not been reported.In this research,wine grape’Cabernet Sauvignon’,table grape’Jumeigui’and’Hutai 8’were used as test materials to explore the effects of ABA concentrations on grape quality.The study showed that application of ABA during fruit veraison had good effect on improving the fruit quality of three grape varieties.100 mg/L ABA turned out to be the best concentration for’Cabernet Sauvignon’because the contents of reducing sugar,total phenol,tannin and other indexes increased significantly.The biochemical indicators of’Jumeigui’and’Hutai 8’increased obviously on 400 mg/L ABA treatment,especially the content of total anthocyanins,which was respectively 5.0 and 6.8 times higher than that of the control.In conclusion,ABA can regulate the appearance and internal quality of grape,but the response of varieties to ABA concentrations was diverse.100 mg/L ABA improved the wine grape’Cabernet Sauvignon’most and 400 mg/L ABA was more suitable for the table grape’Jumeigui’and’Hutai 8’.
