Researches have been made allowing to estimate the influence of initial dense of planting of ing to estimate the influence of initial dense of planting of good cultures on energy of growth of a sessile oak (Quercus petraea Liebl.). It is revealed, that the rare. It is revealed, that the rare. It is revealed, that the rare cultures, planted at a distance of 1x1 m inside the platform, have shown high energy of growth during 6 years of life. While the saplings of oak grew much worse in dense culture (at a distance between 0,5x0,5 m inside the platforms). Thus concluding, the speed of growth of the oak saplings are in a deep relation with the distance of planting between the cultures inside the platform.
