Photosynthesis, transpiration and stomatal response of various species of woody plants exposed to sulfur dioxide. Photosynthesis of Fraxinus excelsior, Piceaabies, Abies alba and Pinus sylvestris declined after 6 and 12 h of fumigation at SO 2 concentrations of 5 and 9mg m −3 . Transpiration also declined, but the maximum depression was only 38%. Stomata began to close after fumigation with ∼ 1 mg SO 2 m −3 for 6 h. The diffusion resistance of needles of Pices and Abies increased after fumigation with 9 mg SO 2 for 6h to a peak value of 35–40 scm −1 and decreased rapidly ( Picea ) or remained stable ( Abies ) during the following 30h.
