Abstract
Variability of diameters of trees is considered in connection with density change of pine plantings with the age of 12 to 30 years. It has been revealed that there is a decrease in the maximum and average diameters due to increase in density in a limited range of density, which decreases with increasing age. Variability of average heights on all variants of experience in different years remains almost constant. There is essentially a smaller variability in artificial forest stands in comparison with natural stands.
