- 摘要:
- 以观赏向日葵种子为试材，采用纸培法，在光照培养箱（25±1）℃条件下,研究了0、2、4、8、12 g/L 5个盐溶液浓度梯度胁迫处理对其发芽率、发芽势、发芽指数的影响。结果表明：盐溶液在2 g/L时，种子发芽率最高，说明观赏向日葵种子在该浓度盐胁迫下最有利生长；随着盐浓度的升高，所有盐胁迫处理与对照相比发芽势、发芽指数都呈下降趋势。盐胁迫浓度在12 g/L时，种子的发芽率、发芽势和发育指数均最低。
- Abstract:
- Taking Helianthus annuus seeds as experimental materials,using the paper culture method,under light incubator (25±1)℃ condition,the effects of 0,2,4,8,12 g/L 5 salt solution concentration gradient stress treatments on the germination rate,germination potential,germination index were studied.The results showed that when salt solution at 2 g/L,seed germination rate was the highest,which showed adaptabity of Helianthus annuus seeds at this salt solution.As the concentration of salt solution increased,compared with the contrast,germination potential and germination index of all treatments showed clear downward trend.When salt solution at 12 g/L,the germination rate was the lowest,germination quality was the poorest,the growth of seeds showed a bad state.
