Abstract
The aim – to evaluate of success Cladrestiis kentukea (Dum.-Cours.) Rudd introduction in conditions of Right-Bank of Forest-Steppe of Ukraine.
Material and Methods. Samples of C. kentukea growing in DP Sofiyivka of the NAS of Ukraine were chosen as model plants. Two groups of plants were formed: 7 samples of 62–67 years belong to first group, 8 samples of 10–12 years – to second group. Life activity of introduced plants was estimated by P.I. Lapina, S.V. Sidneva method (1973) using acclimatization number of M.A. Kokhno and O.M. Kurdyuk. The rate of acclimatization was determined by M.A. Kokhno formula (1994).
Results. The total score of C. kentukea adult individuals conditions had is 96 points, young individuals – 53 points, which indicates that introduction of C. kentukea is prospect. Plants of C. kentukea characterized by annually growth of shoots, the formation of good-quality seeds and self-seeding reproduction, full hardiness and drought resistance in conditions of introduction.
Conclusion. Plants of C. kentukea have а wide ecological plasticity.
