摘　　要：在构件水平上,对川产的3种药用淫羊藿属植物(淫羊藿(Epimedium brevicornu)、箭叶淫羊藿(E.sagitta-tum)、柔毛淫羊藿(E.pubescens))的无性系构件特征、克隆构型及构件生物量配置进行比较,结果表明在野生状态下:该属3个种无性系构件的形态特征差异显著,且存在较大的变异性,变异系数范围在29.29%～48.31%之间;箭叶淫羊藿更趋于"游击型"克隆构型,而淫羊藿和柔毛淫羊藿则更趋于"密集型"克隆构型;该属3个种都将高比例生物量配置到叶片或者根茎,其次为茎,再其次为根。柔毛淫羊藿具有更强的克隆繁殖能力,单位面积上各构件生物量均最大,应作为人工引种栽培的首选种。In order to investigate the morphological characteristics,clonal architecture and biomass allocation of medicinal plants of Epimedium from Sichuan at modular level,three species of Epimedium under the natural conditions were sampled,i.e.,E.brevicornu,E.sagittatum and E.pubescens. The results indicated that the morphological characteristics of clonal modules of three species had significant differences,these clonal modules had large variability,the coefficients of variation （CV） among these clonal modules ranged from 29.29% to 48.31%. Clonal architecture of E.sagittatum tended more to ＂guerilla＂ ,while those of E.brevicornu and E.pubescens tended more to ＂phalanx＂. Three species of Epimedium allocated the highest proportion of biomass to rhizomes or leaves,next to stems,and the last to roots. E.pubescens had the highest clonal ability among three species. The biomass of clonal modules of E.pubescens was the largest in unit area,and E.pubescens preferred to grow in introduction and cultivation.
