摘　　要：对浙江省七叶一枝花（Paris polyphylla var.chinensis）种质资源现状进行连续3年的实地调查。结果表明,七叶一枝花在浙江省分布较为广泛,大多零散分布于海拔500～1500 m的湿润且荫蔽度较大的地带,野生七叶一枝花已处于濒危状况。其16个性状在种源地间和种源地内均存在一定的变异,不同性状之间的变异程度也各不相同,平均变异系数在12.98%～42.64%,不同地区的七叶一枝花形态性状的总体平均变异系数也有差异,为奉化（FH）〉景宁（JN）〉开化（KH）〉遂昌（SC）〉临安顺溪（LS）〉泰顺（TS）〉临安清凉峰（LQ）〉磐安（PA）;主成成分分析结果显示：前6个主成分特征值均大于0.5,累计贡献率达到89.271%,并且株高、冠幅、叶长、叶柄长、花萼宽、花萼长6个性状对形态聚类分析影响最大;UPGMA聚类分析显示,48份种质资源可聚为3类,开化、磐安、泰顺的种质聚为第一类,景宁、遂昌及临安顺溪的种质聚为第二类,临安清凉峰及奉化的种质聚为第三类。Investigations were conducted on germplasm resources of Paris polyphylla var. chinensis in Zhejiang province for 3 continuous years and analysis was made on their phenotype. The results showed that it scattered distributes in the province, under humid and shaded area at elevation of 500-1500m, and it is found endangered. Determinations on transplanted P. polyphylla var. chinensis demonstrated thatl6 phenotypic traits had difference both among and within provenances. There are varied differences among traits with mean coefficient of variation of 12.98%-42.64%.
