摘　　要：研究了Mn2+和Mo6+对棉花种子发芽耐盐性的影响。对苗高、发芽率、发芽指数、活力指数4个指标的测定结果显示:Mn2+和Mo6+混合液浸种对棉花种子发芽的耐盐性有显著影响,其中以Mn2+浓度1 000 mg/kg与Mo6+浓度200 mg/kg混合液效果最佳。Effect of Mn^2＋ and No^6＋ on the tolerance of cotton seed to salt was studied. The result showed that Mn^2＋ and No^6＋ improved some characteristics of the seedling such as the length of seedling, the germination index, the germination rate and the vitality index. Mn^2＋ and No^6＋ had significant effect on tolerance of cotton seed to salt and the treatnmnt with the 1 000 mg/kg Mn^2＋ and 200 mg/kg Mo^6＋ was the best.
