| 摘 要： | 运用灰色关联分析法,对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0.7674、0.7005、0.6793和0.6287,它们可作为3个树种重要的抗旱评价指标。

| Abstract: | 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, water potential in leaves,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 in drought resistance evaluation of the tree species. |
