Climate change has led to increased extreme weather events, such as severe droughts and intense rainfall, with regions in Portugal, like Alentejo and Algarve, being particularly affected. Understanding the influence of water availability in the concentration of phenolic compounds in autochthonous varieties could be an important tool to know how these varieties adapt to water scarcity. This work has been carried out with the aim to analyze the profile of phenolic compounds by HPLC-DAD in four Portuguese grape varieties (Tinta Gorda, Tinta Miúda, Tinta Caiada, and Moreto), cultivated under three irrigation regimes (water comfort, moderate water deficit, and rainfed). The results reveal that Tinta Gorda, Tinta Miúda, and Tinta Caiada varieties exhibit the higher concentrations of phenolic compounds under rainfed conditions. Among these, Tinta Miúda and Tinta Caiada stand out as the most promising varieties in terms of adaptability to water scarcity.
气候变化导致极端天气事件增加，如严重干旱和强降雨，葡萄牙的一些地区，如阿连特茹和阿尔加维，受到的影响尤为严重。了解水分供应对本土品种中酚类化合物浓度的影响，可能是了解这些品种如何适应缺水环境的重要工具。这项工作旨在通过高效液相色谱-二极管阵列检测器（HPLC-DAD）分析在三种灌溉制度（水分适宜、中度水分亏缺和雨养）下种植的四个葡萄牙葡萄品种（廷塔戈尔达、廷塔米乌达（小粒紫）、廷塔卡亚达和莫雷托）中的酚类化合物谱。结果表明，在雨养条件下，廷塔戈尔达、廷塔米乌达和廷塔卡亚达品种的酚类化合物浓度较高。其中，廷塔米乌达和廷塔卡亚达在适应缺水方面是最有前景的品种。
