Independently from its origin, trichloroacetic acid (TCA) as a phytotoxic substance affects coniferous trees. Its uptake, distribution and degradation were thus investigated in the Norway spruce/soil-system using 14C labeling. Visible symptoms of affecting of the plant were also observed. The TCA distribution is given mainly by the transpiration stream. Like in soil, TCA in spruce needles seems to be degraded microbially, presumably by phyllosphere microorganisms coming from soil. Indication of this TCA biodegradation is shown using both antibiotics and axenic plants.
