| 摘 要： | 以三峡库区采集的９份野生红三叶和３份国内外品种为材料，在干旱胁迫下，测定其地上生物量、地下生物量和脯氨酸含量等１０项指标，进行灰色关联度分析。结果表明，筛选出地下生物量、脯氨酸含量和叶绿素ａ含量３项可对红三叶抗旱性进行评价的指标；根据红三叶抗旱性评估模型综合评估值（φk）得出材料的抗旱性排序为：瑞德（Ｒｅｄ）＞ＣＱ５＞ＣＱ９＞多丽（Ｄｏｒｙ）＞ＣＱ２＞ＣＱ４＞ＣＱ７＞ＣＱ３＞ＣＱ１＞巫溪＞ＣＱ８＞ＣＱ６。

| Abstract: | Ten indexes were determined for 9 wild accessions collecting from the three gorges reservoir area and 3 varietie of Trifolium pratense under drought stress at the seedling stage.Screeding identification indexes and comprehensive exaluation were studied by grey correlative degree analysis.The results showed that three indexes including ground biomass,MDA content and chlorophyll a content were important in drought stress.The sequence of drought resistance of 12 T.pratense from strong to weak was: Red>CQ5>CQ9>... |
