Kholodny Institute of Botany NASU popup.description2 Report on scientific research: 297 p., Introduction, 9 chapters, conclusions, reference list, 36 fig., 15 tab., 497 sources.The object of research is fossil pollen and spores, modern pollen of the genera Plantago, Veronica, Verbascum, Scrophularia, Utricularia, Pinguicula, Hippuris, Callitriche. The goal is the reconstruction of the whole picture of the modern Ukraine vegetation since the late Pleistocene, which is based on comprehensive analysis of palaeobotanic and actuobotanic data. The method of research is spore-pollen analysis, light and SEM. By the results of palynological studies of deposits from the Late Pleistocene to Holocene the picture of major changes of vegetation and climate in Ukraine is reconstructed. Palaeobotanic study on the example of model sites (Volyn-Podolia and lowlands of the rivers of the steppe zone) show for the first time, that the primary refuge of heat and broad-leaved wood flora could not exist in the plains of Ukraine during last glaciation maximum. The conclusion of a significant influence on the flora of Ukraine in the Holocene secondary (temporary) refuge of broad-leaved tree species that were common in the interstadial Late Glacial wormings. As a result of palynomorphological researching of genuses Plantago, Veronica, Verbascum, Scrophularia, Utricularia, Pinguicula, Hippuris, Callitriche (93 species) diagnostic features of pollen grains were found to solve specific taxonomic problems, and for the purposes of spore-pollen analysis in determining the fossil pollen grains. Based on morphological features of pollen grains some genera are prompted to the new taxonomic point of view. The history of palynological study from the Upper Pleistocene deposits to Holocene in Ukraine during the 20 century to the present is given.
