摘要
研究了不同浓度NaCl胁迫处理对12个番茄品种种子发芽的影响。结果表明,低浓度NaCl胁迫,对番茄种子萌发有一定的促进作用;随着NaCl胁迫浓度的加大,发芽率、发芽势、发芽指数、活力指数等降低,发芽时间推迟,种子发芽整齐度降低。同一胁迫条件下,不同番茄品种种子萌发有显著差异。
The effects of stress under different NaCl concentrations on seed germination in 12 tomato culti-vars were studied.The results showed that the stress under low NaCl concentrations on seed germination had cer-tain promotion;,inversely,with the increasing of NaCl concentration,the germination percentage,germination energy,germination index,and vigor index decreased,and germination time and seed germinating performance would be delayed and reduced accordingly.Under the same stress conditions,the seed germination among differ-ent tomato varieties were significantly different.
