Nazarenko G. Plant teratomorphs under the conditions of anthropogenously transformed environment in the south-east of Ukraine

Research subjects: teratologic changes of plants Research objectives: to reveal peculiarities of plant teratogenesis and to outline usage perspectives of this phenomenon for phytoindication of anthropogenically transformed environment in the south-east of Ukraine. Methods: methods of field geobotanical investigation (route recognizing and detailed-routed methods), methods of studying and describing of teratological changes of plants, investigation of cotyledonous apparatus in seed progeny of plants, comparative populational-morphologic method, mathematic statistics methods. Theoretical and practical results: Morphologic analysis has been conducted and working classificational scheme of plant teratomorphs has been compiled, regional data base of plant teratogenesis has been formed. General peculiarities of plant teratogenesis in the region and characteristic features of this phenomenon in ecotopes of different categories have been determined. Ecotopic coherence of forming of separate types of teratomorphs and tendency of different taxonomic groups representatives to teratogenesis have been estimated. Informative teratologic indices and possible objects for usage in the system of complex estimation of environmental state have been distinguished. Novelty of introduced: The materials have been generalized for the first time, and special investigation of plant teratogenesis has been conducted in different ecotopes in the regional scale, characteristic features and trends of plant teratogenesis in separate types of ecotopes have been revealed, taxa with the greatest tendency to teratologic changes have been distinguished. Teratomorphs for 68 species, 38 genera and 11 plant families have been revealed for the first time in the south-east of Ukraine. The earlier known data on teratologic variability of a number of taxa have been supplemented. The possibilities of teratogenesis phenomenon usage in phytoindicative investigations have been estimated, and the perspectives of this usage have been outlined. Implementation degree: Separate nominative informative block "Plant teratomorphs in the south-east of Ukraine" is included to the united cadastre data base "Biodiversity of phytobiota of the south-east of Ukraine", that is used by specialists. The results of the research on the subject of the thesis have been used in scientifically-ecological motivation of organizing the territory of natural-reserved fund in Donetsk region. Materials of the thesis are used in teaching lectional and practical courses "Industrial botany" and "Ecologic expertise" for the students of biological faculty of the Donetsk National University. Effectiveness: the proposed usage of plant teratogenesis in phytoindicative and monitoring researches enables to conduct more complete estimation of environment state. Sphere, sector of implementation: industrial botany, phytomonitoring of environment state, preparation of specialists.
