Abstract
Characteristic of plant communities developing in the cereal cultivations of the Podlaski Przełom Bugu mesoregion is presented in the paper. This agricultural region is partially situated in the borders of the ,,Podlaski Przełom Bugu" Landscape Park. Extensive agriculture as well as large soil and microclimatic diversity resulted in occurrence of rich, floristically differentiated agrocoenoses. Three associations from the alliance Aperion spicae-venti were noted in the studied area. Association Vicietum tetraspermae was the most common and inner differentiated. Four subassociations: Vicietum tetraspermae scleranthetosum, Vicietum tetraspermae myosotidetosum, Vicietum tetraspermae typicum, Vicietum tetraspermae consolidetosum and 18 lower syntaxonomic units were distinguished. Plots of Papaveretum argemones, differentiated into 3 subassociations: Papaveretum argemones scleranthetosum, Papaveretum argemones typicum and Papaveretum argemones consolidetosum were noted seldom in the studied area. In the central part of the Podlaski Przełom Bugu mesoregion occurrence of a single plots of Arnoserido-Scleranthetum was noted.
