【摘要】 利用灰色系统理论中的关联分析法对叶用芥菜13个品种与产量有关的8个性状进行分析。结果表明,叶用芥菜产量与其相关性状的关联度为:株高0.716 5、开展度0.799 9、叶片数0.777 2、根重0.782 4、最大叶片长0.769 8、最大叶片宽0.796 0、最大叶柄长0.649 0、最大叶柄宽0.730 9;关联序为:开展度>最大叶片宽>根重>叶片数>最大叶片长>最大叶柄宽>株高>最大叶柄长;计算了各性状的灰色权重。更多还原

【Abstract】 Based on the theory of gray relational system,the relation between the yield and 8 relative agronomic characters of 13 leaf mustard varieties was analyzed.The results showed that the relational grade between the yield and each character was as follows: plant-height 0.716 5;leaf open-extent 0.799 9;the number of leaf 0.777 2;root-wenght 0.782 4;the biggest leaf-length 0.769 8;the biggest leaf width 0.796 0;the biggest petiole-length 0.649 0 and the biggest petiole-width 0.730 9.The relation sequence was:leaf open-extent>the biggest leaf-width>root-weight>the number of leaf>the biggest leaflength>the biggest petiole-width>plant-height>the biggest petiole-length.The gray weight of each character was:w1∶w2∶w3∶w4∶w5∶w6∶w7∶w8=0.119∶0.133∶0.129∶0.130∶0.128∶0.132∶0.108∶0.121.更多还原
