摘　　要：以邯郸333、04264、豫15和409棉花品种为试验材料,进行棉花幼苗生长耐盐性试验,测定其幼苗苗长、POD(过氧化物酶)比活力、叶绿素含量、根系活力以及脯氨酸含量等生理指标,分析比较这些指标间的差异显著性,评价不同棉花品种幼苗生长的耐盐性大小。结果表明:邯郸333的幼苗耐盐性最强,其次为04264,再次为豫15,409最弱。The salt tolerance of cotton seedling growth was studies in this experiment,using seedling of 'Handan 333','04264','Yu 15'and'409' as materials.The height of seedling,activity of root system,leaf chlorophyll content,POD activity and the content of praline were determined and compared.The significance of difference in these indexes was analyzed to evaluate salt tolerance of seedling growth of different cotton varieties.The results showed that 'Handan 333' was the most tolerant to salt,then is'04264'and'Yu 15'.'409' was the least tolerant to salt.
