AB - The effect of weather conditions on height increments of trees was investigated within eight age classes. Weather conditions (temperature and precipitation) were presented using Sielianinow’s hydrothermal index in the quarterly periods and the De Martonne index in the annual periods. Drought index in a given year was found to have a negative effect on height increments of trees in the following year. A significant effect of weather conditions found in a given increment year was observed only in the case of the youngest trees.   ER -
