R. A. STEPEN, S. M. REPYACH
Abstract
It is demonstrated that the basic components of volatile emanations of coniferous forests actively participating in the substance circulation are terpenoid compounds. Reserves of these compounds have been seudied in stands, air and soil of pinr forests, The amount of ether oil is on the average in phytocenoses 200, including in the leaf-fall and forest litter 23 kg/ha. Emission of terpenoids in pine forests, depending on the age and other causes, varies within the limits of 36-86 kg/ha. Together with the emission of these substances and other sources, the total annual mass of soil terpenoids is estimated at 65-80 kg/ha, which amounts to 2-3 % of the mass of humus substances.
