Potassium (K) nutrition is of relevant interest for winegrowers because it influences grapevine growth, berry composition, as well as must and wine quality. Indeed, wine quality strongly depends on berry composition at harvest. However, K content of grape berries increased steadily over the last decades, in part due to climate change. Currently, the properties and qualities of many fruits are also impacted by environment. In grapevine, this disturbs berry properties resulting in unbalanced wines with poor organoleptic quality and low acidity. This requires a better understanding of the molecular basis of K accumulation and its control along grape berry development. This mini-review summarizes our current knowledge on K nutrition in relation with fruit quality in the context of a changing environment.
钾（K）营养对葡萄种植者来说至关重要，因为它会影响葡萄藤的生长、浆果成分以及葡萄汁和葡萄酒的品质。事实上，葡萄酒的品质在很大程度上取决于收获时的浆果成分。然而，在过去几十年中，葡萄浆果中的钾含量稳步上升，部分原因是气候变化。目前，许多水果的特性和品质也受到环境的影响。在葡萄藤中，这会扰乱浆果特性，导致葡萄酒口感失衡，感官品质差且酸度低。这就需要更好地了解钾积累的分子基础及其在葡萄浆果发育过程中的调控机制。这篇综述总结了我们目前在不断变化的环境背景下，关于钾营养与果实品质关系的知识。
