摘要: 通过测定、计算获得40个切花菊品种叶片的6个定性分级性状及叶片的长宽比、尖削度、裂片长宽比、裂片开张度等14个叶形结构参数。以6个定性分级性状为变量, 用聚类法选取叶形相似性大的18个切花菊品种, 通过多元判别分析法对18个品种叶片的形态结构参数进行数值化鉴别。结果表明, 18个叶形相似的品种多元判别的平均拟合率为88.28%, 达到了判别品种的目的。说明根据叶形的测量数据能对切花菊品种进行有效鉴别。

Abstract: By examining 40 cut chrysanthemum varieties, we obtained 6 qualitative classification characters and 14 leaf structure parameters, including ratio of leaf length to width, extent of acumination of leaf tip, ratio of lobe length to width, and notch acuity of lobe. We selected 18 varieties with similar leaf appearance after clustering by the 6 qualitative classification traits. The 18 varieties were differentiated numerically by multiple discriminant analysis. Varieties with similar leaf appearance were distinguished, and the mean identifiable fitness of the 18 cultivars was 88.28% on multiple discriminant analysis. With these leaf measurement data, we can effectively differentiate different cultivars of cut chrysanthemum.
