摘　　要：对三七种植区抽取的10个群体的33个表型性状进行观测。结果表明,同一地区的不同性状间存在差异,而且同一性状在不同地区的差别也很大。地区间,马关种植区平均变异系数较小(c.v.=0.2794),相对较稳定,而砚山种植区变异则较大;性状间,根部性状及生物量性状变异相对较大而且不稳定,最为明显的是地下茎干重,c.v.=0.526。以上分析说明,三七居群间和居群内多型性明显,表型上存在大量丰富变异。34 morphdogical characters of ten Panax notiginseng populations from Sanqi planting region were measured. The results showed that different characters of the same regin sample were different and the same characters in different region as well as were extremely diversified. Among the regions, the average coefficient of variance in Maguan planting region was least （ c. v. = 0. 2794） and relatively stable. Among the characters, variance of the root character and biologic quantity were quite bigger and unstabe, especially dry weight of rhizomes （c. v. =0.526）.
