Sishchuk N. Forestry-selective evaluation of European larch in the north megaslope Ukrainian Carpathians

Object of study - forest culturphitocenoses with European Larch, its plus-trees and its clone seed plantations in the north megaslope of Ukrainian Carpathians. Purpose - to give forest valuation and selection-sha characteristics of a European Larch in the forest culturphitocenoses of the northern megaslope of Ukrainian Carpathians, to study breeding and bioecological peculiarities of functioning of clonal plantations and to improve methods of favorites interspecific hibrydyzatsiynyh clonal seed plantations of different species of larch for heterocyst offspring. Methods of research - forest valuation, selection-shaped, reforestation, phenological, genetic and mathematical-statistical. The scientific novelty. For the first time, after the complex forest valuation and genetics and breeding research of the European Larch in the north megaslope of Ukrainian Carpathians and adjacent areas, it was worked out the ways of keeping the gene pool, the development of plant breeding and seed plantations. It was established the breeding structure of the European Larch trees, features of molded characteristics and properties of trees and their correlations with economically valuable indicators. It was established the dynamics of the intensity of flowering and seeds keeping larch transplants for clonal seed plantations, feature plantation cones and seed fertility variability clones, the degree of its impact on genetic diversity of seeds and future offspring, the level of potential changes in its genetic variation due to the use of different economic activities. The results are improved to the breeding, seed production and genetic conservation of the European Larch in the investigated region. Areas of use: forestry.
