SPECIFIC FEATURES OF REPRODUCTION OF CAMPANULA L. SPECIES IN THE PROCESS OF INTRODUCTION UNDER THE CONDITIONS OF THE SOUTH-EAST OF UKRAINE
Reproductive features of the genus Campanula L. in the course of introduction in the South-East of Ukraine have been identified, their root system morphology has been studied, their biomorphs and capacity of vegetative reproduction have been determined. It has been found out that adaptations of Campanula species manifests themselves in changing the plants root system type from tap-root-cluster-root forms to cluster-root ones (C. carmatica, C. glomerata) and cluster-rhizomatous ones (C. rotundifolia). The adaptations of these species also manifest themselves in formation of leafless shoots in the unfavorable in terms of meteorology years (C. punctata). C. rapunculoides, C. punctata have proved to be vegetatively mobile, C. glomerata, C. poscharskyana, C. carpatica, C. rotundifolia were characterized by a slow vegetative propagation, C. sarmatica is vegetatively immobile. The forest-edge and shrub species of genus Campanula L. have proved to be most adapted to the conditions of introduction in this region, and also the forest and meadow species, either vegetatively mobile or propagating by viable self-seeding.
