Abstract
The composition of volatile organic compounds expired by the plant was investigated in dependence on the environment. Using two-step adsorption-concentration, hydrocarbons were preseparated from oxygen-containing compounds present in metabolites. In addition to gaseous samples water excreted by the plant was also analysed for the content of volatile organic compounds. Using gas chromatography differences were found in the content of unsaturated hydrocarbons, aldehydes and other substances in the metabolites of sick and healthy trees. The greatest differences in the composition of metabolites in dependence on the environment were found in Norway spruce (Picea excelsa), and the lowest for birch (Betula verrucosa).
