| 摘 要： | ３００ ｍｍｏｌ／Ｌ ＮａＣｌ明显抑制大麦幼苗的生长， ＮａＣｌ处理的同时加入 ２０ ｍｇ／Ｌ的 ＧＳＨ可明显增加大麦幼苗干重、根系长度、叶片叶绿素以及Ｋ＋含量，降低Ｎａ＋含量；同时叶片液泡膜Ｈ＋－ＡＴＰａｓｅ和Ｈ＋－ＰＰａｓｅ的活性均明显增加，电解质渗漏率降低．

| Abstract: | The growth of barley (Hordeum vulgare L.) seedling is inhibited by 300 mmol/L NaCl. When 20 mg/L GSH is present in the hydroponic culture solution with NaCl, root length, root and shoot dry weigh, chlorophyll as well as K contents are increased, Na content is decreased. At the same time the activities of H -ATPase and H -PPase associated with tonoplast vesicles isolated from leaves are stimulated, and electrolytic leakage are diminished by exogenous GSH. |
