Leaf senescence induces a massive shift of the nitrogen (N) allocation within plants, but its influence on the storage of yeast-assimilable N (YAN) in grapevine berries is unclear. The aim of this work was to investigate whether the YAN concentration in grape must can be increased by a targeted induction of leaf senescence.

乙烯利诱导的叶片衰老增加了葡萄汁中酵母可同化氮的浓度（Vitis vinifera cv. Riesling）

叶片衰老引起植物内氮 (N) 分配的巨大变化，但其对葡萄藤浆果中酵母可同化 N (YAN) 储存的影响尚不清楚。这项工作的目的是研究是否可以通过有针对性地诱导叶片衰老来增加葡萄中的 YAN 浓度。
