| 摘 要： | 研究了榉树种子在0,0.1%,0.2%,0.4%,0.6%和0.8%等6种NaCl质量分数胁迫下的发芽率以及幼苗生长和部分生理特性的变化。结果表明,NaCl胁迫显著影响了榉树种子萌发和幼苗生长。种子发芽率最高出现在没有盐胁迫的条件下,随着NaCl质量分数的增加,发芽率、发芽指数和活力指数都呈下降趋势。NaCl处理的幼苗根长和苗长在质量分数为0.1%时与对照差异不显著,大于0.1%后明显下降。幼苗SOD和POD活性呈先上升后下降的趋势,而MDA含量呈先下降后升高的趋势。

| Abstract: | Seeds germination and seedling growth of Zelova schneideriana were investigated under six levels of salinity stress e.g.0,0.1%,0.2%,0.4%,0.6%,and 0.8%,respectively.The results showed that salinity restraint affected the seeds germination and seedling growth of Zelova schneideriana significantly.The germination rates was the highest under non-saline conditions.Germination capacity,germination and vitality indexes decreased with the increasing of NaCl concentration.The effects of 0.1% NaCl on the shoot and ro... |
