This monograph studies for the first time the biological principles of the comprehensive utilization of pine forests. In the context of the immense usefulness of the raw material they provide: timber, nuts, and resin. The morpho-physiological, ontogenetic, ecological-geographic, intra- and interpopulation relations between growth, generative, and resin-forming processes in Siberian stone pine have been demonstrated under standard conditions and under conditions of experimental modification of root-leaf proportions. Using a complex evaluation of appropriate indexes of productivity, practical recommendations have been offered for a differentiated combination of elements and types of complex. Suggestions have been examined for the selective breeding of trees and plantations on the basis of economic indexes; growth, yield, and resin output; as well as aspects of yield control. This book is designed for the use of scientific workers in the field of forest science and specialists in forestry.
