Evaluation of growth variability by diameter of European spruce trees of different origin in a changing climate

Abstract

An assessment of the radial growth of various climatic ecotypes of European spruce growing on the territory of the Negorelsky educational and experimental forestry enterprise (Minsk region of Belarus) is given. A significant difference was revealed in the parameters of the average width of annual rings, as well as the proportion of early and late wood in the studied climatic ecotypes of European spruce. The years with the smallest radial growth of trees are noted, as well as the years with the maximum increase in tree diameter.
