摘要
运用灰色关联分析法,对红柳、侧柏和合头草等3个树种的抗旱性与9项抗旱指标的相关性进行了分析。关联度分析结果表明:叶绿素含量、叶水势、叶片相对含水量以及电导率与3个树种的关联度分别为0.767 4、0.700 5、0.679 3和0.628 7,它们可作为3个树种重要的抗旱评价指标。
Applying the method of grey correlative analysis, the correlation of drought resistance of 3 species and 9 drought resistance indexes was analyzed. The results with grey correlative degree analysis showed that chlorophyll content, leaf water potential,leaf RWC （relative water content） and electric conductivity, whose correlative degree with 3 tree species were 0.7674,0. 7005,0.6793 and 0.6287 respectively, can be regarded as the important indexes of drought resistance evaluation of the species.
