摘  要:
采用50、200、400、600、800 mmol/L的NaCl盐溶液处理绿豆种子,以蒸馏水作对照(CK),对绿豆种子萌发能力及速率进行测定分析。结果表明:在种子萌发出芽阶段表现出较强的耐盐性,在50~200 mmol/L的NaCl盐胁迫下对其发芽率影响不明显,但显著抑制幼苗生长;随处理浓度的升高,其萌发、幼苗生长受到抑制的程度增大,绿豆种子萌发能忍耐的NaCl处理浓度为200 mmol/L以下。

摘  要:
Five different concentrations(50、200、400、600、800 mmol/L)of NaCl solution were treated on seeds of Vigna radiata L. compared with the distilled water as control,the seed germination percentage and speed were analyzed. The results showed that different concentrations of NaCl(50~200 mmol/L)didn′ t have obvious effect on the seed germination percentage,but significantly inhibited the growth of seedlings. The seed germination and the growth of young seedling of Vigna radiata L. were inhibited along with the increase of NaCl concentration. The endurable stress of NaCl concentration for the seed germination of Vigna radiata L. is under 200 mmol/L.
