Pugacheva A. Biomorphological peculiarities of Lilium hybridum hort. under introduction to the Ukrainian south-east.

The thesis is devoted to investigation of bioecologic peculiarities of 61 L. hybridum hort. varieties under Ukrainian south-east conditions. Turms and duration of basic phenophases have been fixed. Scheme and code classification of biomorphological and ornamental feature of L. hybridum hort. varieties have been worked out. Peculiarities of vitality and morphology of pollen are studied. Optimal terms of scale separation of L. hybridum hort. varieties have been revealed. Dependance of Asian hybrid scale separation optimal terms on the date of the beginning of their blooming is fixed. The most resulting stimulators are defined. Varieties, the most tolerant to adverse climatic conditions of the introductional region, are singled out. Optimal light conditions for planting material growing have been fixed. The assessment system of L. hybridum hort. varieties by the sum of ornamental and economical-biologic features have been developed. As a result of complex assessment of introduction successfulness 17 varieties perspective to present-day green construction of Donbass have been selected.
