| 摘 要： | 以绿豆种子为材料,研究了预吸胀种子脱水耐性的变化,以及Ca^2 处理对种子脱水耐性的影响。结果表明：绿豆种子的脱水耐性随预吸胀时间的延长而下降;Ca^2 预吸胀处理能提高种子的脱水耐性,适宜的Ca^2 浓度为20mmol／L;Ca^2 能修复预吸胀种子的脱水伤害,适宜的Ca^2 浓度为2．5～5mmol／L。 |
| 关 键 词： | 绿豆种子 脱水耐性 修复 Ca^2＋ |

| Abstract: | Phaseolus radiatus seeds were used as experimental materials,and changes of desiccation tolerance of pre-imbibed seeds and effect of Ca~(2+) treatment on seed desiccation tolerance were studied in this paper.Results indicated that desiccation tolerance of P.radiatus seeds decreased with pre-imbibition,and that pre-imbibition treatment of Ca~(2+) could increase seed desiccation tolerance and optimal Ca~(2+) concentration was about 20 mmol/L,and that Ca~(2+) could repair dehydration damage of pre-imbibed seeds and optimal Ca~(2+) concentration was approximately 2.5~5 mmol/L. |
| Keywords: | Phaseolus radiatus seed desiccation tolerance repair calcium |
