ЛУЧНІ ФІТОЦЕНОЗИ ПОЛТАВЩИНИ: ІСТОРИЧНІ АСПЕКТИ ДОСЛІДЖЕНЬ ІЗ СЕРЕДИНИ ХІХ ДО КІНЦЯ ХХ СТОЛІТТЯ

The article analyzes literary sources and archival information on the study of meadow phyto-coenoses within the Poltava region from the middle of the XIXth to the end of the twentieth century. The scientific achievements of scientists and research institutions that studied the flora of Poltava region have been identified and described. In the process of historical research in this period, we have identified two stages of development of meadow and described the main directions of work. The first stage (from the middle of the 19th to the 30th years of the 20th century) can be called regional studies. There was accumulation of floristic data in selected areas, scientists first united species according to characteristic features. Vegetation of the Poltava region was studied by Е.R. Trautfetter, V.V Montrezor, A.S Rogovich, I.F. Shmalgauzen, they compiled the first lists of wi-ldlife flora in the region. V.V. Dokuchaev organized an expedition to study the botanical and geog-raphical features of the flora. An important contribution to the development of mowing is the work of A.M Krasnov, V.F. Nikolaev V.P. Kushnirenko, under their management were organized studies of the grasslands of the valley of the Vorskla River to classify the vegetation cover. The works of this stage are the basis for further study of the flora of the region. Floristic-cenotic and systematic trends are developing. At the second stage (from the 1930's to the 1990's, the twentieth century), the interest of scientists towards meadow phytocoenoses increases as the basis for effective agri-culture. Actively worked in this direction L.G. Ramensky, M.V. Kuksin, Ye.M. Lavrenko, V.O. Cherkasova, M.O. Bikodir, P.S. Makarenko. Their works are devoted to the issues of increasing pro-ductivity and rational use of natural pastures and grassland. Environmental protection work in Po-ltava region is connected with the scientific activities of such scientists as D.S. Ivashin, R.V. Ganzha, O.A. Stasilunas, V.M. Samorodov, T.P. Golova, M.D. Litvinova. The main areas of work are geobotanical, resource-oriented and ecological.
