| 摘 要： | 针对草地早熟禾品种（系）萌发期对盐分最敏感的特点，对15个草地早熟禾品种（系）在不同盐浓度胁迫下的萌发特性进行研究，测定其发芽率、发芽势和相对盐害率等的变化情况，结果显示031315草地早熟禾和031322草地早熟禾2个品系用0.8%NaCl胁迫时的发芽率都在35%以上，即这2个品系萌发期的耐盐胁迫能力较强。

| Abstract: | Kentucky bluegrass is sensitive to salinity stress at germination stages.In this paper,germination properties of 15 Kentucky bluegrass varieties were tested under different salt concentration.The results from germination rate,potential and relative injury rate showed that under 0.8% salinity stress,the germination rate of 031315 Kentucky bluegrass and 031322 Kentucky bluegrass were all over 35%,that was to say they were salt tolerance at germination stage. |
