Research Abstract

Spatial pattern of genetic structure between plant species of different sexual systems, Elatostema umbellatum var. majus (dioecy) VS E. laetevirens (monoecy) and Dryopteris erythrosora (asexual) VS D.caudipinna (sexual), were analysed using molecular analisys. Genetic differentiation of dioecious species was not higher than those of monoecious species. D. caudipinna on Izu Island was dispersed to disturbed area. These results suggest that difference of sexual system of plant species might not effect the genetic structure of these species.
