Abstract

Population diversity of an understorey aroid, Schismatoglottis irrorata, was analyzed based on the proportion of individuals with and without B chromosomes. The number of B chromosomes varied not only among individuals but also within the same root tip. They were considered not to be active genetically. Statistic tests indicate that isolated populations significantly differed regarding their B chromosome proportions, which might have arisen from the founder effect and the genetic drift by geographical isolation.
