摘 要 ：干早胁迫下，玉米幼叶生长部位质膜Ｈ＋－ＡＴＰ酶活性显著上升，游离脯氨酸、可溶性糖和无机离子亦同时在玉米叶片生长部位大量积累，二者之间呈明显的正相关．质膜Ｈ＋－ＡＴＰ酶的专一性抑制剂Ｎａ３ＶＯ４在干旱胁迫下强烈抑制游离脯氨酸的积累，说明ＰＭＨ＋－ＡＴＰａｓｅ参与了玉米叶片的渗透调节过程．

Abstract:The PMH+-ATPase activity increased considerably under osmotic stress,at thesame time a great accumulation of free Pro,soluble sugars and some inorganic ions was built in the growing region of maize leaf.There.was an obvious direct relationship between suc
