| 摘 要： | 以盐敏感小麦品种鲁麦15为材料,研究不同浓度外源硫化氢(H2S)对NaCl胁迫下小麦种子萌发率、发芽指数、活力指数和幼苗生长状况的影响。结果表明,一定浓度的外源H2S能够缓解NaCl胁迫对小麦种子萌发和幼苗生长的抑制。0.01～0.13 mmol/L NaHS浸种预处理12 h均能不同程度地缓解100 mmol/L NaCl对小麦种子萌发率、发芽指数、活力指数和幼苗生长的抑制作用。其中以0.05 mmol/L NaHS浸种预处理效果最好。

| Abstract: | The salt-sensitive wheat cultivar LM15 was used to examine the effect of exogenous hydrogen sulfide on seed germination rate,germination index,vigor index and seedlings growth under salt stress.The results showed that seed pretreatment with exogenous H2S could alleviate the NaCl-induced seed germination inhibiton and seedlings growth,seed priming with 0.01～0.13 mmol/L NaHS for 12 hours alleviated the seed germination rate significantly,germination index,vigor index and growth of seedlings of wheat under 100 mmol/L NaCl stress.The optimal concentration of NaHS was 0.05 mmol/L. |
