Description
Summary:Forest breeding should be produced not only by the representatives of the local flora, which is not very diverse in some areas of the Republic of Kazakhstan, but by species and forms of trees growing in temperate zones of the worldwide. In particular, this refers to arboretums located in the conditions significantly different from the place of natural growth of the introduced species. One of this arboretum is the JSC "Forest nursery" of the Ministry of Science and Higher Education of the Republic of Kazakhstan which is located in the South-East of the republic.The aim of this study was to study the ecological and genetic variability of coniferous introducents in the foothill desert-steppe zone and to determine the share of genetic and environmental factors. The variability and the relative stability of the expression of the quantitative trait in ontogenesis, which characterizes the species adaptation to the new conditions in 9 Yellow pine trunks, Crimean pine trunks and Scots pine trees, 7 Blue spruce trees and the same number of trees in European spruce, in which annual increments of the height of one morphological Location.Beginning with the growth of 2014 and then sequentially down the trunk, so long as lateral branches of the first order in whorls were preserved or traces were observed in a good way. Thus, the value of the mean squares differs significantly in the increments of a single morphological location and in the increments of tree groups, in the introductions species and in the periods of their life. Therefore we are allowed to conclude that there are still some parts and interference in the estimation of the ecological, genotypic and phenotypic dispersions that have different values and are manifested to a greater extent, or in the analysis of increments of tree groups, or increments of one morphological location, that is, they change the cause of their display.
