Response of Scots pine ecotypes in geographical crops to climate change

\nThe current sanitary condition of trees and stands of forest-steppe and steppe ecotypes of Scots pine is considered in relation to responses to climate change. Based on wood cores taken from 96 model trees in 62-year-old seed progenies of pine of different geographical origin on 32 sample plots, trends in the change in the width of annual rings and their structure by calendar years are established, and the magnitude and nature of responses of tree growth of different pine ecotypes to climate change are shown.\n
