| 摘 要： | 以萝卜(Raphanus sativus L.)种子为材料,采用纸上萌发法研究了不同浓度的Na2CO3对萝卜种子萌发的影响。结果表明:2mmol·L-1的Na2CO3处理对萝卜种子的发芽率、发芽势、发芽指数、活力指数、胚芽长、胚根长和胚鲜重等均有一定的促进作用。显著抑制萝卜种子萌发的Na2CO3浓度为5mmol·L-1,显著抑制胚根生长的浓度为5mmol·L-1,显著抑制胚芽生长的浓度为10mmol·L-1。

| Abstract: | Taking radish seed as material,the effect of Na2CO3 stress on seed germination of radish was studied.The results showed that 2 mmol·L-1 Na2CO3 promoted the germination rate,germination potention,germination index,vigor index,germ length,radicle length and fresh weight of radish embryo.The concentrate of Na2CO3 above 5 mmol·L-1 significantly inhibited radish seed germination.The concentrate of Na2CO3 above 5 mmol·L-1 significantly inhibited radicle length.The concentrate of Na2CO3 above 10 mmol·L-1 significantly inhibited germ length. |
