NaCl胁迫对菜用大豆光合作用及叶绿体抗氧化系统的影响
本文采用蛭石栽培，选用菜用大豆盐敏感品种‘理想高产95．1’（LX）和耐盐品种‘绿领特早’（LL）为试材，设对照和NaCl胁迫2个处理，对照根部浇灌营养液，NaCl胁迫处理根部浇灌溶有NaCl的营养液。结果表明，NaCI胁迫显著降低了2品种菜用大豆的净光合速率（Pn），降低了2品种菜用大豆的过氧化物酶（POD）、抗坏血酸过氧化物酶（APX）、脱氢抗坏血酸还原酶（DHAR）、谷胱甘肽还原酶（GR）、谷胱甘肽过氧化物酶（GPX）的活性，显著提高了H2O2含量；耐盐品种LL维持了相对较高的Pn及APX、DHAR、GR、GPX活性和相对较低的H202含量。本试验表明，保持叶绿体AsA—GSH循环持续快...

| Abstract | 本文采用蛭石栽培，选用菜用大豆盐敏感品种‘理想高产95．1’（LX）和耐盐品种‘绿领特早’（LL）为试材，设对照和NaCl胁迫2个处理，对照根部浇灌营养液，NaCl胁迫处理根部浇灌溶有NaCl的营养液。结果表明，NaCI胁迫显著降低了2品种菜用大豆的净光合速率（Pn），降低了2品种菜用大豆的过氧化物酶（POD）、抗坏血酸过氧化物酶（APX）、脱氢抗坏血酸还原酶（DHAR）、谷胱甘肽还原酶（GR）、谷胱甘肽过氧化物酶（GPX）的活性，显著提高了H2O2含量；耐盐品种LL维持了相对较高的Pn及APX、DHAR、GR、GPX活性和相对较低的H202含量。本试验表明，保持叶绿体AsA—GSH循环持续快速、有效运转，降低叶绿体膜系统受伤害程度，维持叶肉细胞较强的光合活性，可能是耐盐品种LL维持较高Pn的重要生理基础之一。 |

Vegetable soybean salt sensitive eultivar ＇ lixianggaochan 95-1＇ （LX） and salt tolerant eultivar ＇ lvlingtezao＇ （LL） were selected as tested materials. The results showed that NaCl stress significantly reduced net photosynthetic rate （Pn）, reduced the activities of perexidase （POD）, eorbate peroxidase（ AP |
