Pine production potential on semihydromorphic edafotope of Belarusian Polesje under changing climatic conditions

Abstract

There are presented the results of the study of the pine tree-ring growth dynamics in the regional semidimorphic and climatic conditions of Belarusian Polesje. It has been shown that the production potential in the increase in stem mass of trees in a bilberry pine is individual. The maximum individual tree-ring growth does not coincide with the calendar and does not depend on weather and climate conditions, with the exception of years with meteorological anomalies. Resource capabilities of pine for the growth of stem mass decreased in the second half of the 20th century and the beginning of the 21st century after lowering the groundwater as a result of drainage reclamation and during climate warming with relative aridization.
