Biomorphological analysis rare component flora of Kodymo-Elanetsky Bug region
Scherbakova O. F. Summary:
Characterization of morphological features complexes of rare component flora life forms, carried out
under its biomorphological analysis allowed to establish mechanisms of species morphophysiological
adaptation to the conditions of characteristic floristics complexes. Herbaceous polycarpic plants (49,
74.2%) dominate in the spectrum of biomorph of rare species in the region. Most of them (50; 75,7%)
are characterized by monocentric biomorphs. Dominated rare species (40; 60,6%) with a fibrous root
system which, in comparison with taproots (26, 39.4%), are more characteristic for forest and meadow
floristic complexes. It is shown that species with a rosette and semi-rosette suckers have a wider ecological
coenotic plasticity, they are more adapted to the Steppen and Granitopetrophyton floristic complexes of
the region with extreme megathermal, and xerophytic, and geliophytic conditions.
