Проведено дослідження видового складу лучної квіткової флори в околицях с. Весела Долина
Глобинського району Полтавської області. Встановлено, що флора досліджених лучних фітоценозів нараховує 68 видів, які належать до 64 родів та 27 родин. Серед виявлених покритонасінних рослин дводольні види переважають над однодольними. Перше місце у спектрі родин флори належать родині Asteraceae (23,4% від загальної кількості). Високі місця займають такі інші провідні родини флори: Fabaceae та Poaceae (9,3%), Rosaceae та Lamiaceae (7,8%). Перші 5 провідних родин включають 60,2% від загальної кількості видів. Індекс видового багатства на одну родину лучної флори становить 2,5.
Проведено исследование видового состава луговой цветочной флоры в окрестностях с. Веселая Долина Глобинского района Полтавской области. Установлено, что флора исследованных луговых фитоценозов насчитывает 68 видов, относящихся к 64 родам и 27 семействам. Среди выявленных покрытосеменных растений двудольные виды преобладают над однодольными. Первое место в спектре флоры принадлежат семейству Asteraceae (23,4% от общего количества). Высокие места занимают такие ведущие семейства флоры: Fabaceae и Poaceae (9,3%), Rosaceae и Lamiaceae (7,8%). Первые 5 семейств включают 60,2% от общего количества видов. Индекс видового богатства на одну семейство луговой флоры составляет 2,5.
The study of the species composition of the floral flora of meadow phytocoenosis in the vicinity of the village Vesela Dolina of Globyno District of Poltava Region. Such an elucidation of the taxonomic structure of the meadow flora makes it possible in the future to not only rationally use the onion vegetation, but also to better understand the processes occurring in the phyto-environment, to maintain them at the proper level and improve. It has been established that the flora of studied grassland has 68 species, which belong to 64 genera and 27 families. Among the detected angiosperms, dicotyledonous species predominate over monocotyledons. Percentage of representatives of dicotyledons was 88.3%, and monocots – 11.7%. The bulk of the floristic composition of the investigated meadow grasslands is occupied by the leading by number of genera and species of the family, which determine the nature of the flora of the region. The first place in the spectrum of families of flora belongs to the family Asteraceae (23.4%). The following other leading families of flora include: Fabaceae and Poaceae (9.3%), Rosaceae and Lamiaceae (7.8%), Caryophyllaceae (4.6%), Brassicaceae, Ranunculaceae and Boraginaceae (3.1%), Butomaceae, Polygonaceae, Juncaceae, Caprifoliaceae, Plantaginaceae, Urticaceae and others (1,6%). The first 5 leading families comprise 60.2% of the total number of species. The seventh place was occupied by representatives of the family Brassicaceae, which is an indicator of a significant rerralization of the territory. This suggests a clear degradation and synantropy of meadow grass, which is manifested in reducing the participation of the cereal component and the predominance of species from the grass group and is a consequence of the violation of the operation of meadow phytocoenoses. The calculated average index of species richness for one family of meadow flora is 2.5. Comparison of the spectrum of the leading families of the flora of the study area with the meadow flora of the Left Bank Forest-steppe of Ukraine, the flora of the Poltava region, the Middle Dnieper, the Left Bank Dnieper, it can be argued that it is characteristic of the flora of the forest-steppe zone, and also reflects its ties with boreal flora and the flora of the Mediterranean. The largest species richness is distinguished by Melilotus, Trifolium, Artemisia, Potentilla, and the rest of the genera is 1 species. An analysis of the generic spectrum showed that in the meadow flora of monotypic genera 93.75% of the total and cover 88.24% of the species. According to calculations for one genus there are 1,06 species. Consequently, the systematic structure of the flora of Vesela Dolina of Globyno District of Poltava Region reflects the typical flora of the Left Bank Dnieper and Poltava regions in particular. The spectrum of the leading families of the territory as a whole is similar to the flora of Ukraine and is related to the location of the region between the forest-steppe and steppe zones.
