The aim of this work, which was conducted in 2017 and 2018, was to gain insight into the effects of regulated deficit irrigation (RDI) treatments on the content of soluble sugars, organic acids and endogenous hormones in Cabernet Sauvignon. The RDI treatments slightly decreased the hundred-grain weight and total acid content before vintage but significantly increased the soluble solids content, juice pH and reducing sugar content. The glucose and fructose contents were increased by the RDI treatments, and the ratio of G:F was reduced. Most genes associated with sugar unloading were upregulated by RDI, especially in the RDI1 group. The tartaric acid, malic acid and citric acid contents were decreased by RDI. Under the RDI treatments, the ABA content increased from E-L 33 to 38, and the IAA, GA, JA-Me and BR contents decreased from E-L 33 to 34. The results of this study ultimately benefit the promotion of RDI measures, and our data might be useful for the improvement of wine grape quality.
本研究于 2017 年和 2018 年进行，旨在深入了解调控亏缺灌溉（RDI）处理对赤霞珠果实中可溶性糖、有机酸和内源激素含量的影响。RDI 处理略微降低了采收前百粒重和总酸含量，但显著增加了可溶性固形物、果汁 pH 值和还原糖含量。RDI 处理增加了葡萄糖和果糖含量，降低了 G:F 比。与糖卸载相关的大多数基因都被 RDI 上调，尤其是在 RDI1 组。RDI 处理降低了酒石酸、苹果酸和柠檬酸的含量。在 RDI 处理下，ABA 含量从 E-L33 增加到 38，IAA、GA、JA-Me 和 BR 含量从 E-L33 减少到 34。本研究的结果最终有利于 RDI 措施的推广，我们的数据可能有助于提高酿酒葡萄的品质。
