Taxonomic and typological structure of the flora of Eastern Podilia (Ukraine)

Abstract

On the basis of herbarium data, literary and cartographic sources, own field research with subsequent critical-system processing of the collected material, an inscription of the flora of Eastern Podilia was compiled, which includes 1210 species belonging to 526 genera and to 123 families. The taxonomic structure of the flora of the investigated area includes five divisions, where the Magnoliophyta division with 1183 species is dominant (97.2%). The authors have also established the biomorphological structure of phytogenic manures of the region, 88.6% of which belong to herbaceous plants. The majority of species belong to polycarpic 736 (60.8%), monocarpic (17.4%), and young (10.4%) species. It should be noted that when assessing phytobiota by the Raunkiaer eco-biomorphic index, it was found that hemicryptophytes (47.9%) and tetophytes (22.2%) prevailed in the studied flora. Cryptophytes, which are divided into geophytes, gelophytes, and hydrophytes, constituted 17.6%, and phanerophytes and hamefites 12.3%. As a result of studies on the ecological and coenotic structure of the flora of the region, there are 16 categories of ecological structure. The dominant group is the meadow-steppe – 191 species (15.8%), rayon – 185 species (15.3%), and non-forest species – 183 species (15.1%) of vegetation.
