摘要
通过研究不同浓度NaCl溶液对赤小豆和红豆种子萌发及幼苗生长的影响,探讨赤小豆和红豆的耐盐能力。结果表明:随着NaCl浓度升高,赤小豆和红豆的发芽率、发芽势、发芽指数、活力指数、耐盐指数均显著降低,等浓度NaCl处理下,红豆的发芽率、发芽势、发芽指数、活力指数、耐盐指数均较赤小豆高,且萌发抑制率相对较低。赤小豆与红豆幼苗根长、芽长和鲜重均显著降低,等浓度NaCl处理下,红豆幼苗的根长、芽长和鲜重指标均较赤小豆高。研究表明红豆比赤小豆耐盐性更强,更能在盐胁迫环境下生长。
The effects of NaCl solutions of different concentrations on seed germination and seedling growth of adzuki bean and red bean were studied to investigate the salt tolerance of adzuki bean and red bean.The results showed that:With the increase of NaCl concentration,the germination rate,germination potential,germination index,vigor index,salt tolerance index of adzuki bean and red bean decreased significantly.At the same time,the germination rate,germination potential,germination index,vigor index and salt tolerance index of red beans were all higher than those of adzuki beans under NaCl treatment of equal concentration,and the germination inhibition rate was relatively low.The root and bud length and fresh weight of both adzuki bean and red bean seedlings were significantly reduced,under the treatment of equal concentration NaCl,both root and bud length and fresh weight indexes of red bean seedlings were higher than those of adzuki bean.In conclusion,this study showed that red bean had stronger salt resistance and could grow better than adzuki bean under salt stress.
