| 摘 要： | 盐胁迫下大麦叶片K+含量下降， Na+含量上升， K+/Na+比下降， 叶绿素(chl)含量下降， 叶片内源谷胱甘肽(GSH)含量与K+/Na+比、 叶绿素含量呈极显著的正相关。 外源GSH处理可明显提高活性氧清除系统中超氧物歧化酶(SOD)、 过氧化氢酶(CAT)、 谷胱甘肽还原酶(GR)、 过氧化物酶(POD)活性以及抗氧化剂GSH、 类胡萝卜素(Car)、 维

| Abstract: | Under 300 mmol L-1 NaCl stress, the content of Na+ increased, the contents of K+, chlorophyll(chl) and K+/Na+ ratio decreased in the leaves of two barley varieties differing in salt tolerance. The positive correlation between glutathion(GSH) content and K+/Na+ ratio as chlorophyll content was signif |
