The growth of geographical crops of Scots pine on drained lands

Abstract

The research analyzes observation materials and condition assessment of 100-year geographical Scots pine forest cultures created in 1913 by professor Ogievsky V D on drained lands of the Okhta forestry territory to study the intensity of Scots pine trees growth depending on the seeds origin. The planting material was grown from seeds collected in the northern, southern, eastern, southwestern and central parts of Russia. The growth of Scots pine cultures was studied and changes in wood stock, trees amount, annual increments, influence of meteorological factors on radial increments were analyzed depending on the origin of the planting material. The results of research show that sustainable and highly productive cultures can be grown from seeds of northern and eastern regions of Russia.
