盐胁迫对台湾相思幼苗形态及相关生理指标的影响OACSTPCD
Effects of salt stress on seedling morphology and related physiological indexes of Acacia confusa
为探寻台湾相思种子的耐盐情况,在其种子萌发期和幼苗期分别进行不同浓度盐胁迫试验.结果表明:低浓度NaCl胁迫可提高种子发芽率,随着NaCl浓度的增高,种子发芽势、发芽率、活力指数以及发芽指数均不同程度降低,且和对照有显著差异.通过拟合台湾相思发芽率和NaCl胁迫浓度回归曲线,发现种子萌发期台湾相思适宜的最大NaCl胁迫浓度为203.87 mmol/L,NaCl致死浓度为383.16 mmol/L;幼苗期台湾相思叶鲜重、茎鲜重、根鲜重、主根长、株高…查看全部>>
In order to explore the salt tolerance of A.confusa seeds,different concentration gradients of NaCl solution were used to conduct salt stress tests during the seed germination and seedling stages.The results showed that low-concentration NaCl stress could increase the germination rate of seeds.With the increase of NaCl concentration,the germination potential,germination rate,vigor index and germination index of seeds all decreased to varying degrees,and were…查看全部>>
