以7个不同品种高粱为试材,对其在萌发期和苗期的耐盐性进行鉴定.结果表明:高粱在生长的不同阶段对盐分的敏感性不同,苗期比萌发期耐盐性差;品种间的耐盐性存在明显差异,杂交种与亲本相比,在萌发期和苗期的耐盐性方面杂交种明显优于亲本,说明在盐渍地上选育高耐盐性高粱杂交种是可行的.
Seven varieties of sorghum were used as materials to evaluate their salt tolerance at germination and seedling stage.The results showed that sorghum had different salt sensitivity at different stages of growth and salt tolerance at seedling stage was lower than that at germination stage. Salt tolerance of cultivars were significantly different. Hybrids showed significantly better salt tolerance at the germination and seedling stages than the parents, indicating that the selection of high salt tolerant sorghum hybrids on saline soils feasible.
