| 摘 要： | 用不同浓度的NaCl、Na2CO3和Na2SO4盐溶液处理绿豆的种子,对绿豆种子的发芽率、发芽速度、发芽指数的影响进行测定分析.结果表明:绿豆在种子萌发出芽阶段表现出较强的耐盐性,在100～200 mmol/L的NaCl和Na2SO4胁迫下对绿豆种子发芽率影响不明显,但显著抑制幼苗生长.在低浓度Na2CO3胁迫下绿豆种子萌发、幼苗生长均受到明显抑制,说明绿豆不耐碱性盐Na2CO3.

| Abstract: | Solutions of various concentration of NaCl,Na2CO3 and Na2SO4 were used for saline stress to measure and analyse the seed germination percentage and speed,index of Phaseolus radiatus by saturating the seeds.The result showed that different concentrations of NaCl and Na2SO4(100~200 mmol/L) didn't decrease growth of the seeding,but the low concentration of Na2CO3 restrain. |
