The effect of planting density on reproductive development and the growth of siberian cedar pine
Abstract
A comparative analysis of indicators of reproductive development of 53–55-year-old Siberian cedar pine trees growing in the suburban area of Krasnoyarsk with different planting density (400 and 5000 pcs/ha) was carried out. The prevalence of specimens that entered the reproductive stage of development in sparse growing conditions was
revealed by 2.75 times in comparison with thickened plantings. The influence of planting density on the yield of Siberian cedar pine is noted. On trees with better growth conditions with a lower planting density, a significantly larger number of cones were formed.
Trees growing on plantations have a larger trunk diameter, thicker branches in the lower part of the crown, but 2.5 times the length of the beetle-free zone than trees growing at a higher density.
