| Summary: | The effect of temperature and precipitation was studied on pine (Pinus sylvestris L.) radial increment in pine forests in southern Tomsk Oblast, West Siberia, Russia. The most tree ring width is produced by the lower temperatures in the growing season, the higher winter and spring temperatures and the higher summer precipitation in the current hydrological year. The positive correlation between the ring width and the higher spring and summer (since April till July) precipitation and the negative correlation between the width and the higher winter (since December till January) precipitation are found during winters with less snow cover. During the last century (1900-2000) the tree radial increment significantly depends on April and September temperatures and June precipitation in all pine forests studied and is satisfactory explained by seasonal patterns of physiological and growth activity of pine trees and by seasonal changes of soil climate in southern West Siberian Plain. |
