| 摘 要： | 对NaCl盐胁迫下番茄种子萌发特性进行了研究和品种间比较,研究了不同浓度盐处理下种子发芽势、发芽率、萌发时间和萌发整齐度、简化活力指数、耐盐指数及幼苗生长的情况.结果表明:盐胁迫下,2个品种番茄发芽势、发芽率、简化活力指数和耐盐指数均呈下降趋势;胚根/胚芽比在低盐浓度时呈现下降趋势,但随浓度增加而呈上升趋势.说明低盐浓度可刺激种子萌发,但在较高盐浓度胁迫下种子活力下降,下降程度的差异说明耐盐性不同;随盐浓度增加,种子的萌发时间延长,萌发整齐度下降,品种不同萌发时间和萌发整齐度不同.

| Abstract: | The variation of germination characteristics were studied and compared among varieties to determine the effect of NaCl stess on seed germination of tomato.The seed germination potential,germination percentage,germination time and regularity,vigor index,salt-tolerance index and the growth of seedlings were studied.The result showed that the germination potential,germination percentage,vigor index and salt-tolerance index of two varieties decreased with the increasing of NaCl concentration;The radicle/embryo ... |
