摘要: 本试验研究了钾营养对玉米抗旱性的影响,结果表明:高钾营养有助于改善玉米叶片的水分状况,提高玉米叶片的渗透调节及气孔调节能力,增加原生质耐旱性,对细胞膜也具有保护作用。

关键词: 玉米, 钾营养, 抗旱性

Abstract: This experiment researched effects of potassium nutrition on drought resistance of maize leaves. The results showed that high potassium nutrition could improve water condition of maize leaves, increase osmotic and stomatal adjustment capacity, enhance drought tolerance of protoplasts, and also protect cytomembrane.

Key words: Maize, Potassium nutrition, Drought resistance
