摘要: It was attempted to study the effect of stand density on stem form Scots pine trees. To estimate index SDI Reineke (1933) used. The analyses carried out showed that has no significant values breast height and specific factors. detailed analysis curve permitted conclude affects top part profile. Trees in stands low comparison with trees high are characterized by lower relative diameters stem, especially range from 0.7 0.9 tree height. However, differences profiles different only 0.82 0.89 Using empirical equation for determination volume does not increase its accuracy.
