为探讨干旱胁迫对葡萄果实花色苷代谢的影响,本研究以‘赤霞珠’葡萄为试验对象,设置了干旱胁迫组(DR)和正常生长无干旱胁迫对照组(CK),采集成熟期果实样本进行非靶向代谢组学测序,通过偏最小二乘法判别分析(PLS-DA)、聚类分析和代谢分析等方法,分析与花色苷相关的代谢物质。PLS-DA表明主成分1(PC1)和主成分2(PC2)对总变异的贡献率分别为59.31%和21.05%,二者累计贡献率达80.36%,样本间分类效果显著;聚类分析表明,在DR、CK中共检测到氯化芍药素-3-O-阿拉伯糖苷等17种花青素差异代谢物和原花青素B1等7种原花青素差异代谢物。干旱胁迫后的葡萄花青素类物质含量较CK显著降低,原花青素类物质含量较CK则升高。本研究为‘赤霞珠’葡萄抗逆栽培及其品质提升提供参考。

To explore the effect of drought stress on anthocyanin metabolism in grape fruits, this study used ‘Cabernet Sauvignon’ grapes as the experimental subjects and set up a drought stress group (DR) and a normal growth control group without drought stress (CK). Fruit samples at the mature stage were collected for non-targeted metabolomics sequencing. Metabolic substances related to anthocyanins were analyzed through methods such as partial least squares discriminant analysis (PLS-DA), cluster analysis and metabolic analysis. PLS-DA indicated that the contribution rates of principal component 1 (PC1) and principal component 2 (PC2) to the total variation were 59.31% and 21.05% respectively, and the cumulative contribution rate of the two reached 80.36%, with significant classification effects among samples. Cluster analysis indicated that a total of 17 differential metabolites of anthocyanidins such as Peonidin-3-O-alpha-arabinopyranoside and 7 differential metabolites of proanthocyanins such as Procyanidin B1 were detected in DR and CK. The content of anthocyanidin substances in grapes after drought stress was significantly lower than that of CK, while the content of proanthocyanidins was higher than that of CK. This study provides a reference for the stress-resistant cultivation of ‘Cabernet Sauvignon’ grapes and the improvement of their quality.
