| 摘 要： | 对94份甜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，发芽率呈现出下降趋势。不同品种（系）间的耐盐能力存在明显差异，按盐害百分率分级，1级品种（相对盐害率〈20％）5份，3级品种（相对盐害率20％-40％）17份，5级品种（相对盐害率40％-60％）36份，7级品种（相对盐害率60％～80％）15份，9级品种（相对盐害率≥80％）21份。其中芽期耐盐性强（耐盐级别3级以上）的高粱品种22份，占供试材料的23．40％。

| Abstract: | Seed germination of 94 sweet sorghum cultivars were investigated through simulating salt stress at different salinity levels.The results indicated that with the increasing of salinity,all materials showed a decrease to various extents in germination rate and germination potential.The salt tolerance of different cultivars was obviously different.The 94 sorghum varieties were classified based on relative salt-injury rate.Five of them were fallen into the first-level tolerance,while 17 into the third-level tolerance,36 into the fifth-level tolerance,15 into the seventh-level tolerance,and 21 into the ninth-level tolerance.There were 22 varieties with high salt tolerance,whose relative salt-injury rate was less than 40%. |
