摘要
目的:对滇重楼不同居群进行形态学差异研究,为滇重楼的遗传多样性研究和良种选育提供依据。方法:采用田间试验设计,对滇重楼不同种源进行根、茎、叶、花的性状进行观察、测量,并进行统计分析。结果和结论:滇重楼遗传多样性丰富,群体内形态差异普遍存在。主成分分析显示,花部特征及花萼数、花瓣数、柱头心皮数、雄蕊数等是造成不同居群形态差异的主要因素;基于形态性状的聚类分析结果显示欧式距离为45.08时,滇重楼居群分为2类,2个类群显著的形态差异是叶面积指数的大小。
Objective： To study the morphological variations of Paris polyphylla var. yunnansensis in different population for genetic diversity and breeding. Method ： The characters of roots, stalks,leave and flowers were observed. The results were analyzed by DPS software. Result and Conclusion： P. polyphylla var. yunnansensis showed plenty genetic diversity, there existed obvious differences in morphological characters of different population. Principal components analysis showed that the number of calyces, petal, carpels, stamens is main factor,which causes the morphological variations in different population. Cluster analysis shows that 26 populations are incorporates in two types as 45.08 Euclidean distance. Leaf area index is distinct different in this two types.
