Gryshka National Botanical Garden NAS of Ukraine popup.description2  Final report on the GDR: 311 pages, 113 figures, 74 tables, 115 sources. Objects of research: forest and meadow-steppe phytocenoses of the botanical and geographical areas of the NBS of the National Academy of Sciences of the National Academy of Sciences of the Russian Academy of Sciences, the biosphere reserve "Askania Nova" and the Carpathian Biosphere Reserve, agrocenoses of barley, corn and soybeans at the sites of the Agrobiostation of the National University of Bioresources and Nature Management (Pshenichne village, Vasylkiv district , Kyiv region), tundra ecosystems of Galindez Island of the Wilhelm Archipelago (Coastal Antarctica). The purpose of the work: to study the peculiarities of the formation of reservoirs and flows of Carbon and Nitrogen depending on soil processes, the composition of vegetation and microbiocenosis in order to find out the functional relationships between the components of natural and artificial biogeocenoses. The task of the research: to develop the concept of studies of Carbon and Nitrogen exchange in natural and model forest and meadow-steppe biogeocenoses. The influence of stress factors associated with climatic changes on the circulation of allelopathically active compounds in the plant-soil system was studied. The microbiological component of the transformation of Carbon and Nitrogen in the soils of the investigated biogeocenoses was analyzed. Research methods. Methods of field observations, biotests, microbiological and physiological-biochemical studies were applied. The vital state of plants was assessed by physiological and biochemical indicators of growth and development, photosynthesis, activity of enzymatic and non-enzymatic antioxidant protection systems. Key words: ecosystems, agrobiogeocenoses, allelopathy, chlorophyll index, antioxidant protection, photosynthetic potential, pools, streams, Carbon, Nitrogen, steroids, laccase Product Description popup.authors Ivanytska Bohdana Oleksandrivna Bedernichek Tymur Yu.
