| 摘 要： | 研究了不同浓度盐胁迫对罗布麻种子萌发及幼苗生长的影响。结果表明:对照及盐浓度为20%条件下种子萌发率最高;随着盐胁迫增加,SOD、POD活性及脯氨酸含量先增大后减小,在盐浓度60%处达到最大值;MDA的含量先减小后增大,在40%处达到最小值。表明一定浓度的盐胁迫可以促进罗布麻幼苗的生长,种子萌发以无盐及低盐环境最好。

| Abstract: | Studied the effects of salt stress on seed germination and young seedling growth of Apocynum venetum.The results showed that the optimal germination was obtained under control conditions and salt content was 20%;With the rising of the salt stress,the activities of SOD,POD and the praline content first increased and then reduced,and they reached the maximum values when salt content was 60%;The contents of MDA first were reduced and then increased as concentrations of the salt increased,and they reached the minimum values when salt content was 40%.These results suggested that the seedling growth of Apocynum venetum suitable for some concentrations of salt,but its seed germination was suitable for saltless and low-salt environment. |
