| 摘 要： | 对103份高粱种质资源在发芽期进行耐盐性鉴定.结果表明,随着盐浓度的升高,发芽率、发芽势呈现出下降的趋势.不同品种(系)间的耐盐能力存在着明显的差异,按盐害百分率分级,1级品种(相对盐害率＜20%)11份,3级品种(相对盐害率20%～40%)27份,5级品种(相对盐害率40%～60%)32份,7级品种(相对盐害率60%～80%)18份,9级品种(相对盐害率≥80%)14份.其中芽期耐盐性强(耐盐级别3级以上)的高梁品种38份,占供试材料的36.8%.

| Abstract: | Seed germination was investigated on 103 sorghum seed samples through simulating salt stress designed at different salinity Ievels.The results indicated that with the increasing of salt stress,all materials showed a decrease to various extents in germination rate and germination potential.Salt tolerance of cultivars was significantly different.103 sorshum varieties were classified based on relative salt-injury rate.11 of them were fallen in first-level tolerance,27 in third-level tolerance,32 of them in fifth-level tolerance,18 in seventh-level tolerance,and 14 in ninth-level tolerance.And 38 varieties with high salt tolerance(relative saltinjury rate less than 40%),account for 36.8%in studied materials. |
