| 摘 要： | 对玉米耐盐系和盐敏感系在不同浓度盐胁迫下生理变化研究的结果表明,与盐敏感系相比,玉米耐盐系叶绿素含量高,脯氨酸、MDA含量及组织外渗液的相对电导率低,且变化幅度小。随盐浓度的增加,玉米耐盐系和盐敏感系的SOD、POD活性均先增加后降低,但玉米耐盐系峰值出现较晚。耐盐系的CAT活性明显大于盐敏感系;地上部分Na/K值小于盐敏感系,且增加的幅度小,而地下部分正相反。

| Abstract: | The physiological and biochemical changes of salt-tolerant line and salt-sensitive line of maize under the different concentrations of salt stress were determined.The results indicated that there were more chlorophyll content,less praline and MDA contents,and lower relative conductivity of organization of external seepage of salt-tolerant line with a small change,compared with salt-sensitive line.With the increase of salt concentration,the activities of SOD and POD of maize increased firstly,and then decrea... |
