| 摘 要： | 目的]为研究Na2CO3和NaHCO3等碱性盐对植物的胁迫伤害提供依据。方法]用不同浓度的Na2CO3和NaHCO3溶液处理菊苣种子,并对其发芽率、发芽势、根长、苗长和鲜重等生理指标进行研究。结果]低浓度Na2CO3和NaHCO3对萌发后菊苣的苗长、根长和鲜重有一定的促进作用,但对根苗比的影响表现为抑制。结论]低浓度Na2CO3和NaHCO3对种子萌发有增效效应。

| Abstract: | Objective ] The research aimed to provide the basis for the study of the damage of the stress of basic salt such as Na2 CO3 and NaHCO3 on the plants. Method] Chicory seeds were treated with Na2CO3 and NaHCO3 solution of different concentration. The physiological indicators such as germination rate, germination potential, root length, seedling length and fresh weight were studied. Result ] A low concen- tration of Na2CO3 and NaHCO3 could promote germination rate, germination potential, then promote seedling length, root length and fresh weight after germination. However, it showed the performance for suppression on the ratio of root and shoot. Conclusion] A low concentration of Na2CO3 and NaHCO3 had synergistic effect on chicory seed germination rate and germination potential. |
