| 中文摘要: |
| 运用灰色关联分析法,对5项抗旱指标与5个紫花苜蓿(Medicago Sativa)品种抗旱性的相关性进行了分析。关联度分析结果表明:各指标与苜蓿品种抗旱性的关联序为:游离脯氨酸含量>SOD>POD>相对含水量>叶片水势。各指标对苜蓿抗旱性的影响,以游离脯氨酸含量最大,其次为SOD及POD;再次相对含水量;而叶片水势的影响最小。 |

| Applying the method of grey correlative analysis．the correlative of drought ressistance of5varieties and 5drought ressistance indexes was analyzed．the results with grey correlative degree analysis showed that：the order of correlative degree of drought ressistance and indexes of 5alfalfa was：Pro＞SOD＞POD＞RWC＞leaf water potential．Which meaned that the effection of different indexes to5alfalfa varieties drought resistance were：the Pro was biggest and than SOD、POD and were bigger the leaf water protential was the weakest． |
