Increased Ammonium Enhances Suboptimal-Temperature Tolerance in Cucumber Seedlings.

ABSTRACT: Nitrate nitrogen (NO₃^--N) is widely used in the cultivation of the cucumber (Cucumis sativus L.). In fact, in mixed nitrogen forms, partially substituting NO₃^--N with NH₄⁺-N can promote the absorption and utilization of nitrogen. However, is this still the case when the cucumber seedling is vulnerable to the suboptimal-temperature stress? It remains unclear as to how the uptake and metabolism of ammonium affect the suboptimal-temperature tolerance in cucumber seedlings. In this study, cucumber seedlings were grown under suboptimal temperatures at five ammonium ratios (0NH₄⁺, 25%NH₄⁺, 50%NH₄⁺, 75%NH₄⁺, 100%NH₄⁺
