| 摘 要： | 通过对八个大麦品种种子萌发期间进行NaCl 胁迫实验研究.结果表明,随着NaCl 胁迫浓度的增大,种子发芽率、发芽指数逐渐降低,相对盐害率增加,种子萌发受到的抑制作用明显增强;80 mmol/L 的NaCl 浓度是大麦种子萌发的阀值.不同大麦品种对NaCl 胁迫的敏感程度不同,供试品种中以盐90260和C2118为萌发期较为耐盐的大麦品种.其它品种对盐分胁迫相对敏感.

| Abstract: | Effect of NaCl stress on the seed germination of eight barley cultivars were studied.The result shoued that seed germination rate and germination index reduced,relative harm rate of salt increased simultaneously,with the increasing of NaCl stress concentration.So the inhibitive effect on seed germination obviously increased by NaCl stress.We found that the sensitive NaCl concentration of seed germination is 80mmol/L.Those barley cultivars have different salt sensitivity under NaCl stress.Yan90260 and C2118 ... |
