摘要：

对引自湖北武当山、湖南南部和西北部的12个居群盾叶薯蓣的生长状况及叶形、叶色、叶长、叶宽、叶基、叶张角等12个形态指标进行了观测和比较分析,并测定了各居群的叶和块茎中的皂苷元含量.结果表明:1)在置信水平λ=8.0340时,11个居群可划分成2大类型:①长叶型:主要形态特征为叶片长度大于宽度,中裂片相对较长;②宽叶型:主要形态特征为叶片宽度大于长度,中裂片相对较短;2)不同居群盾叶薯蓣花序数、叶片总数、开花时间、花期长短、茎干重、叶干重等存在显著的差异;3)不同居群皂苷元含量差异也较显著,居群块茎中薯蓣皂苷元含量最高达3.98%(3号)、最低(7号)仅0.33%,而居群叶中约莫皂苷元含量最高达4.27%(4号)、最低(2号)为0.98%.
