【 摘 要 】

This paper presents an analysis of forty-five-year dynamics of the main characteristics of white (Populus alba L.), gray (Populus canescens Sm.), black poplar (Populus nigra L.) and willow (Salix alba L.) stands on the territory of the Khoper State Natural Reserve on the basis of the materials of permanent test plots restored and newly established by A I Sivolapov in 1972 for the purpose of selection of the most productive and stable clone micropopulations of these species. The annual changes taking place in the sample plots, and considerable statistical material, make it possible to carry out quantitative and qualitative analysis of the behavior of the existing associations of white, gray, black poplar and willow with great certainty. Selected highly productive genotypes have been uterine trees to create varieties and are recommended for plantation cultivation.
