摘要:
以海马齿(Sesuvium portulacastrum)为材料,通过水培试验研究了在5个NaCl胁迫水平(0,5,10,20,30 g/L)的海马齿的根系活力、可溶性蛋白质含量以及总抗氧化能力,探讨海马齿植株对盐胁迫环境的适应性. 研究结果显示,在0~30 g/L NaCl盐胁迫范围,随着培养液中盐胁迫强度的增加,海马齿根系活力的变化趋势是先升后降; 在0~20 g/L盐胁迫范围,海马齿根系活动均随盐胁迫培养浓度的增大而显著升高; 到最高胁迫浓度30 g/L时,其根系活力才显著降低.总体上
Abstract:
In order to explore the adapted ability to salt environment,the root activity,the soluted protein content and the total antioxidant capacity of Sesuvium portulacastrum were researched under the stresses by treating with a series of salt concentrations.Five levels of NaCl(0,5,10,20,30 g/L)were used in the experiments.The results showed that the root activities significantly increased with the treat concentration increasing in the range of 0 to 20 g/L,but decreased with the treatment by 30 g/L salt concentration. In general,the soluted protein content of S. portulacastrum decreased under the treating salt stress,while the total antioxidant capacity increased. In the range of treatment salt concentration,the root activities and the soluted protein content could reach the increasing peak with the treatment by 20 g/L salt concentration.The results indicated that S. portulacastrum is more salt-tolerant and it can successfully adapt to the salt habitat environment.
