Reproductive biology of flowering plants and problems of rational nature management
The paper presents the results of the study of reproductive biology of a number of valuable plants introduced to the South of Russia, as well as rare species of flora of the Crimea. Comparative analysis and understanding of the processes of generative structures formation, pollination, fertilization and seed formation of representatives of different families (Anacardiaceae, Annonaceae, Ericaceae, Magnoliaceae, Rosaceae, Rhambaceae, Davidiaceae, Nyssaceae) allowed to establish some regularities in the reproduction system, to make a conclusion about the systematic affiliation and rather high reproductive potential of the studied species. The possibilities of using knowledge of reproductive processes of flowering plants in solving various biological problems: systematics and phylogeny, identifying patterns of formation of generative structures, determining the strategy of reproduction and conservation of plant diversity, the importance of antecological aspects in plant reproduction, breeding and nature protection are shown. The material is of scientific interest to specialists in various fields.
