- 摘要:
- 为将多年生黑麦草应用于大庆盐碱地区园林绿化,以快速建坪,研究了不同浓度NaHCO3胁迫对多年生黑麦草名仕1生理指标的影响。结果表明:随着NaHCO3胁迫浓度的增加,胁迫5 d后多年生黑麦草名仕1相对电导率、MDA含量、CAT、SOD活性及可溶性糖含量均显著上升。在中盐处理下,抗性表现最强,高盐处理下忍耐力下降,反映出多年生黑麦草名仕1在盐胁迫环境中适应性的变化,具有抵御中度盐胁迫的能力。
- Abstract:
- In order to apply Lolium perenne L. for landscaping of saline land in Daqing,the effect of different NaHCO3 concentration on physiological indexes of Lolium perenne L. Neruda 1 were studied.The results showed that with the increasing of the NaHCO3 concentration,after salt stress for 5 days,the relative electrical conductivity,MDA content,CAT activity,SOD activity and soluble sugar content of Lolium perenne L. Neruda 1 were significantly increased.Under the treatment of moderate salt stress,it showed strong resistance,under the treatment of high salt stress,the resistance decreased,which reflected the change of adaptability to salt stress of Lolium perenne L. Neruda 1,so it had the ability to resist moderate salt stress.
