摘要:
对中国东北地区6种3变种30份野生百合的23个形态性状进行了研究。结果表明,我国东北地区野生百合种质资源的主要数量性状均有明显差异,其中花柱长和叶宽的变异系数较大,分别为59.49%和54.03%。基于形态性状,把30份野生百合聚类并划分为两大类:第1类为茎粗壮、花朵较大的种类,包括卷丹和毛百合;第2类为花朵相对较小的种类,包括有斑百合、大花百合、细叶百合、垂花百合、大花卷丹、东北百合和朝鲜百合。通过主成分分析,前4个主成分代表了形态分化的82.51%,即叶长和宽、外轮花瓣宽、内轮花瓣长和宽、花蕾长、花柱长、花药长8个性状是其形态分化的主要指标。

Study on Numerical Taxonomy of Wild Lilies Native to Northeast China
()
Abstract:
The 23 morphological characteristics from 30 accessions of 6 Lilium species and 3 varieties native to Northeast China were studied in this paper.The results showed that there were obvious differences in numerical characteristics among these wild lilies and the variation coefficient of style length and leaf width were highest with 59.49%and 54.03% respectively.Based on the morphological data,30 wild lilies were clustered into two groups.The first group included L.lancifolium,and L.dauricum with thick stem and large flower.The second group included L.concolor var.buschianum,L.concolor var.megalanthum,L.pumilum,L.cernuum,L.leichtlinii var.maximowiczii,L.distichum and L.amabile with the smaller flower.In principal component analysis,the first four principal components represented 82.51% of the morphological differentiation.These characteristics consisted of leaf length and width,outer petal width,inner petal length and width,flora bud length,style length and anther length.
