Abstract

The large-scale environment pollution and its fatal influence on forest ecosystems has led to deterioration of a sanitary condition of forests in Belarus, to reduction of their biological resistance, to mass reproduction of many destructive insects and fungous diseases. The common pine - one of the basic forest creators in Belarus - is widely used as object for test due its high sensitivity to contamination. A number of works offer to use alterations in content of separate ingredients of an essential oil of a common pine as biochemical indicators of terrain industrial pollution. It is necessary to note also, that the basic biochemical processes in needles cells fade during the autumn-winter period, and radioactive disintegration does not stop, that causes the accumulation of radioactive products and, finally, leads to increase of stressful loading on the tree biomass. It was note, that the biochemical indicator - essential oil componential composition - is rather sensitive to quantitive changes of toxic elements and radioactive nuclides in conifer needle. The mechanism of influence of various elements on biosynthesis terpenoids is complicated enough, however some similarities in influence of toxic elements and radioactive nuclides on the process is marked.
