Abstract
Results of the investigation of radial growth of Larix cajanderi Mayr and Pinus sylvestris L. in Central Yakutia are presented. The time span of the set wood ring chronologies is more than 200 years. The application of dendroclimatological methods in studying tree growth within the range of permafrost rocks allowed us to reveal their close interconnection with climatic factors and hydrothermal conditions of soils. A significant correlation between ground temperature and humidity at different depths with the radial growth of larch and pine in Central Yakutia was revealed for the first time by means of statistical anаlysis.
