| 摘 要： | 利用灰色系统理论中的关联度分析法对韭菜单株产量构成的6个主要性状进行分析。结果表明，韭菜单株产量与其相关性状的关联度为：株高0．6033，叶鞘长0．6380，叶片数0．5977，叶片长0．5904，叶片宽0．4664，叶鞘粗0．6134；关联序为：叶鞘长〉叶鞘粗〉株高〉叶片数〉叶片长〉叶片宽。各性状的灰色权重为w1：w2：w3：w4：w5w6=0．1719：0．1818：0．1703：0．1682：0．1329：0．1748。

| Abstract: | Based on the theory of gray relational system,the analysis was made between the per -plant yield and the 6 relative agronomic characters in 6 leeks varieties.The results showed that the relational grade between the yield and each characters is as follows plant-height 0.603 3 ,leaf sheath length 0.638 0,leaf number0.597 7,leaf length0.590 4,leaf width0.466 4,leaf sheath hickness 0.613 4.The relational sequence is long sheath> sheath thickness>plant-height>leaf number>leaf length>leaf width.The gray weight of... |
