ON THE DISTRIBUTION OF SPECIES OF THE GENUS POPULUS L. IN THE MOUNTAIN TUGAI FORESTS OF KAZAKHSTAN

Abstract

The article provides an analysis of literature, herbarium materials and results of the authors' own research on clarifying the species diversity and distribution of representatives of the genus Populus L. in the mountain tugai forests of southern and southeastern Kazakhstan. The dynamics of nomenclature of the two most significant species since the middle of the last century is shown. Plant communities with P. macrocarpa (P. talassica) are found in river valleys from the Dzhungarian Alatau to the Western Tien Shan at altitudes of 1200-2200 m above sea level. Communities with P. afganica have been recorded by us in the valleys of the Badam, Aksu, Bosturgai rivers (Western Tien Shan) and Charyn (foothills of the Northern Tien Shan) at an altitude range of 961-1160 m above sea level. For the purpose of in-depth study of these species, it is necessary to conduct molecular genetic identification of samples from various geographical populations of the southern and southeastern regions of Kazakhstan.
