The influence of chemical treatment of young stands on pine layer in formed middle-aged mixed forest stands

Abstract

The long-term impact of earlier conducted silvicultural treatments on the parameters of the growing stock and the timber density of pine in mixed conifer stands in blueberry-cranberry for-est type is observed. At the experimental plots due to chemical treatment at the stage of young stand and subsequent thinning forests of different composition and growing stock were formed to the present time. On the control plot without any measures conifers are not currently exist. The relationship between indicators of macro structure of pine xylem with wood density is given.
