Pavlova M. Introduction of ornamental wild-growing bulbous geophytes in Donbass. - Manuscript.Thesis for a candidate's scientific degree of Biology, speciality 03.00.05 - Botany. - National botanic garden M.M. Grisko, Kyiv, 2004.

The thesis is devoted to complex researches of 41 kinds, 1 type and 4 forms of the ephemeroidous bulbous geophytes of the diverse ecological-geographical diffusion strange in Donbass. The features of the morphometrical characteristics of the vegetative and generative members in conditions of open soil of Donbass have been investigated. The features of a seasonal rhythm of development of wild-growing bulbous geophytes in crop have been revealed: the causes of the phenological phases shift of the beginning of vegetation and florescence of the investigated kinds have been determined; on the basis of the studying of modes of seasonal develop-ment 4 phenological rhythm types have been defined. The ontogenesis of 10 kinds in conditions of the crop has been investigated, the questions of reproductive biology of all the investigated kinds are covered. The evaluation of the intro-duction successfulness and the evaluation of the kinds on the set of ornamental and economic-biological qualities have been carried out, that enabled to recommend the investigated kinds for the use in greenery planting in the south-east of Ukraine. The ways of use of wild-growing bulbous geo-phytes in modern greenery planting have been developed.
