    Description

    The aim of this paper is to determine tile optimal physiological indicator in diagnosing the condition of tree stands under the stress of industrial pollution. Based on experimental results of the fumigation on pine seedlings with sulphur dioxide, acid rain treatment, and the effect of heavy metals on the seedlings, it is reasonable to use the secondary substances or the so called stress metabolites for this purpose. The greatest changes under the stress of industrial pollution are in the content of essential oils in pine needles. The contents of essential oils were examined and compared in regions with different levels of industrial pollution. The results of this study permit us to conclude that the alpha-pinene content in pine needles is the optimal indicator for the early diagnosis of the condition of woody plants under the stress of industrial pollution.
