| Abstract: | Results of an investigation of radial growth of Larix cajanderi Mayr and Pinus sylvestris L. in Central Yakutia are presented. The time span of the constructed tree-ring chronologies is more than 200 years. Dendroclimatological analysis revealed a close relationship of tree growth on permafrost soils with climatic factors and soil hydrothermal conditions. A significant correlation of radial growth of larch and pine trees in Central Yakutia with soil temperature and moisture at various depths was found for the first time by statistical analysis. |
