Аннотация: Presented are the dendroclimatic research results on annual growth rings of spruce, fir, pine, birch and aspen growing in the middle taiga subzone of Central Siberia. The study established the general annual growth ring variability patterns for the conifers (spruce and fir) as well as for the hardwoods (birch and aspen), with the correlation coefficients between their chronologies estimated at 0.38 and 0.46 (p < 0.001), respectively. It is shown that under the given conditions the influence of the climatic factors accounts not more than for 53.5% of the variability in radial increment. For pine this influence is less clearly pronounced because of the content of the more mixed (compared with the other species of this territory) climatic signal. It is found that the temperature conditions of June are of first importance for all species under investigation. For birch and aspen the dependence of radial increment on the amount of precipitation in June is explained by moisture depletion at the period of the most active growth. В© 2009.
