Description

Clone structure, mortality and reproduction of two populations of a stoloniferous clonal plant, Arabis flagellosa were investigated in its northern distribution range in Japan. Vegetative spread by establishment of terminal ramets of a single stolon dominated the recruitment of both populations. Intermediate ramets in a stolon may rooted but did not survive. No surviving seedling was observed in two years. Daughter ramets were exposed to a much more mortality than mother plants. Once established, the vegetative daughter ramets are potentially stoloniferous and flowering in the next season. The two populations differed in most of the traits measured. Plants in Kibune produced longer but fewer stolons than Fujiwara-dake plants. Production of inflorescences was the most differentiated trait between the two populations. Only one plant in 1989 and four plants in 1990 produced inflorescences in Kibune. In contrast, more than 40% of plants reproduced sexually in Fujiwara-dake in both years.
