Growth dynamics of progenies of Scots pine proveniences in plantations of 1975 in the Left bank Forest-Steppe

Abstract
Growth and quality indices of provenance tests of the second generation of Scotch pine which was planted in 1975 in the Left bank Forest-Steppe are analyzed. Growth dynamics of progenies of provenance groups for up to 37 years old is considered. Progenies were determined that are the best and the worst by average height. Ranks for average height of three the best groups (from Central Federal District and Pryvolzhya of Russia, Belarus) do not change at the age from 3 to 37 years. This provenience groups are the best as by stem quality. Difference in adaptation to forest-steppe conditions is determined for geographical origins from local southern populations of the former USSR and from the central part of area. Adaptation of Scots pine from local southern populations of the former USSR to forest-steppe conditions appears to be slower than populations from the central part of habitat.
