| 摘 要： | 在盆栽控盐的条件下，研究红桤木在0g/L，2 g/L，4 g/L和6 g/L的盐胁迫下生长量、生物量、叶绿素、POD、SOD等指标的动态变化过程。实验结果表明：随着盐胁迫程度的加重，红桤木的株高、生物量、根冠比、叶绿素含量都显著减少；2 g/L的盐胁迫对红桤木的影响与对照相比差异不显著，茎和叶生物量略高于对照，叶绿素含量在胁迫前期高于对照。在胁迫前期和中期POD、SOD活性随着胁迫的加重而上升；在盐处理后期，6 g/L的盐胁迫下的POD活性急速下降，2 g/L的盐胁迫下SOD和POD活性开始上升。 |

| Abstract: | Under the condition of salt-control (0 g/L,2 g/L,4 g/L and 6 g/L) in pot culture, the dynamic changes of plant height,biomass, chlorophyll content, SOD activity, POD activity ofAlnus rubra was studied. The result showed that with the increase of salt-stress,the plant height, biomass, root-shoot ratio and chlorophyll content ofAlnus rubra decreased remarkably. Under 2 g/L level of salt stress, the plant height, biomass of root and root-shoot ration had no obvious difference in contrast to the control group, ... |
