As inner bark tissues in young twigs and branches are able to perform photosynthesis, the effects of different air pollutants to chlorenchymal photosynthesis were examined. Short time exposure to selected air pollutants was studied in the aqueous phase to mimic the apoplastic cellwall environment and the inhibitory concentrations were compared between leaf, stem, bark and proper wood photosynthesis of trembling aspen (Populus tremula L.). Peridermal tissues proved to be effective barriers for pollutant diffusion. Photosynthetic cells of the proper wood seemed to be most tolerant, a fact that needs further studies."@en . .
