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