Genetic Analysis on Three Different Life Cycle Plant Populations, Leynus chinensis, Ambrosia artemisiifolia and Rhodiola sachalinensis in Northeast of China

Abstract

The allozyme and RAPD technologies in this paper were used to investigate ecologically genetic characteristics of natural population of Leynus chinensis, Ambrosia artemisiifolia and Rhodiola sachalinensis in northeast of China. The populations of them separately displayed characteristics of steady, expansive and endangered. According to the theory of plant life cycle forms established by Zu, they belong to Vegetative growth form (V), Sexual reproduction form (S) and Clone reproduction form (C). The result of allozyme and RAPD analyses indicated that genetic diversity and genetic differentiation in population corresponded with classification by this theory. This will provide an alternative for us to understand and assess the ecologically genetic characteristics of different populations.
