Monoterpene patterns of different tissues and plant parts of Norway spruce (Picea abies L. Karst.).
Norway spruce saplings (Picea abies L. Karst.) were exposed for five years to controlled concentrations of ozone and/or sulphur dioxide in open-top chambers. The monoterpenes of needles, twigs (bark and wood), bark and buds harvested from these trees were qualitatively and quantitatively analysed by combined gas chromatography-mass spectrometry. Different tissues and plant parts, showed notable differences in their percentage distribution. However, comparison of the monoterpene patterns of corresponding plant material obtained from trees which had been exposed to different fumigation regimes showed no significant effects of these pollutants.
