摘　　要：葡萄着色是葡萄生长过程中的重要环节,对葡萄品质有极为重要的影响。本文以9年生弗雷葡萄品种为对象,研究了新型脱落酸功能类似物萘酮戊酸(natenpac)对田间葡萄果实着色及品质提升的影响。在果实着色初期,以萘酮戊酸有效成分2、5、10 mg/L 3个质量浓度梯度分别进行叶面喷雾、灌根或浸果处理,以清水处理为空白对照。通过对果实平均横径、颜色、单果重等表观变化以及可溶性固形物、花青素、可溶性糖含量等内在品质的变化进行综合分析,以确定最佳的施药方式和浓度。结果表明:以叶面喷雾和灌根处理,萘酮戊酸可使弗雷葡萄较对照提前7~10 d完成着色,显著提高了果实中可溶性固形物含量和着色程度,同时浆果横径和单果重也略有提高。不同处理方式对使用效果影响显著,灌根和叶面喷雾效果优于浸果,其中以叶面喷雾2 mg/L的处理效果最佳。本研究明确了萘酮戊酸对弗雷葡萄的最佳施药方式和剂量,可为指导萘酮戊酸在葡萄着色中的田间应用提供依据。Grape coloring is an essential stage in the grape ripening process,which has a very important influence on the quality of grape berries.In this paper,nine-year-old grape variety Frey was used as the research object and the influences of a novel abscisic acid(ABA)functional analog,natenpac,on grape coloring and quality improvement in the field were studied.At the initial stage of fruit coloring,foliar spraying,root irrigation,and fruit soaking were carried out with 2,5,and 10 mg/L natenpac,respectively,and clean water treatment as the blank control.By comparing the apparent changes,such as average transverse diameter,color,and single fruit weight,and internal quality changes,such as soluble solids,anthocyanin,and soluble sugar contents,the optimal application mode and concentration were determined.The results showed that natenpac could make Frey grape finish coloring 7-10 days earlier than the control by foliar spraying or root soaking modes,and contributed to significant increases in soluble solid content and coloring degree,and slight increases in the transverse diameter and single fruit weight of berries.The three treatment modes showed a great difference in efficacy.Root irrigation and foliar spraying were better than fruit soaking and 2 mg/L of foliar spraying was the best.This study clarified the best application mode and concentration of natenpac to Frey grape and provided the basis for guiding the field application of natenpac in grape coloring.
