Abstract
A breeding system of the gynodioecious Geranium pseudosibiricum J. Mayer in three meadow and meadow-steppe communities of the Altai Mountains was investigated. Statistically significant differences in the morphology of flowers between hermaphrodite and female plants have been established (p 0.001). The stamens of pistillate flowers in females are reduced and do not produce pollen. Statistically significant differences between the sexes in seed productivity have been established: female plants form several times more fruits than hermaphrodite ones (p 0.01); a high female compensation was detected for G. pseudosibiricum. Infertile hermaphrodite plants were found in the coenopopulations. Female palnts in the coenopopulation CP1 constitute 55% of the total number of generative plants. In natural habitats, G. pseudosibiricum is characterized by good seed breeding and successful formation of offspring, which contributes to the maintenance of female plants in the coenopopulations of the species. The features of breeding system of G. pseudosibiricum have revealed significant differences between female and hermaphrodite plants.
