Allozyme investigation of the five Cimicifuga taxa in Korea was conducted to assess genetic and clonal diversity within populations and genetic divergence among populations and taxa. Levels of allozyme variation maintained in Korean Cimicifuga taxa were comparable to those for most herbaceous perennials. In general, samples excluding copies of the same multilocus genotype maintained higher levels of genetic diversity than the total samples within populations. Copies of homozygous genotypes at several loci resulting from clonal spread lead to decreased levels of genetic diversity within populations, indicating that clonal reproduction found in Cimicifuga affects population genetic structure. In general, more widely distributed species such as C. dahurica and C. japonica harbored higher levels of allozyme diversity than the other taxa examined. Although two varieties of C. heracleifolia are geographically and reproductively isolated, the genetic and clonal structure of var. bifida seems to resemble var. heracleifolia, indicating that the two varieties may have had a similar evolutionary history. However, the allozyme data strongly indicate that the two morphological types (Groups I and II) of C. simplex should be treated as separate species.

韩国升麻科（毛茛科）等位酶变异及遗传关系

对韩国五种升麻类群进行等位酶研究，以评估种群内的遗传和克隆多样性以及种群和分类群之间的遗传差异。韩国升麻类群中保持的等位酶变异水平与大多数多年生草本植物相当。一般来说，不包括相同多位点基因型拷贝的样本比种群内的总样本保持更高水平的遗传多样性。由克隆传播导致的几个基因座纯合基因型的副本导致种群内遗传多样性水平降低，表明在升麻中发现的克隆繁殖影响种群遗传结构。一般来说，分布更广的物种，如 C. dahurica 和 C. japonica 比其他被检查的分类群具有更高水平的等位酶多样性。虽然 C. heracleifolia 的两个变种在地理上和生殖上是孤立的，但是 var. 的遗传和克隆结构。bifida 似乎类似于 var。heracleifolia，表明这两个品种可能具有相似的进化历史。然而，等位酶数据强烈表明，C. simplex 的两种形态类型（I 组和 II 组）应被视为单独的物种。
