Abstract
The paper presents the results of a comparative study of the reproductive biology of a number of Crimean flora species and valuable plants introduced to the south of Russia belonging to various families (Magnoliaceae, Annonaceae, Ericaceae, Campanulaceae, Anacardiaceae, Lamiaceae, Ranunculaceae, Davidiaceae, Nyssaceae, Onagraceae, Papaveraceae), which made it possible to establish some features and regularities in the formation of the generative structures of the reproductive system, consisting in the conjugation of the development of male and female elements, the maturation of sexual gametes and the process of pollination in entomophilous plants. A conclusion was drawn concerning the high reproductive potential of the studied species, which is expressed in the formation of a sufficient number of full-fledged seeds to reproduce. The possibilities of using the knowledge of the reproductive processes of flowering plants in solving certain issues of taxonomy, determining the strategy of reproduction and conservation of phytodiversity, and showing the importance of antecological aspects in plant reproduction, breeding and nature protection were demonstrated. The material is of scientific interest to botanists, ecologists, breeders and other specialists.
