The influence of SO 2 on the metabolism of SO 2 ‐tolerant and SO 2 ‐sensitive seedlings of Scots pine was investigated. Under the influence of SO 2 changes were observed in 14 CO 2 assimilation, in 14 C‐fixation pattern and in 14 C‐translocation. The changes were more marked in the SO 2 ‐sensitivc plants than in the more tolerant ones. The inhibition of 14 C‐transport from needles to roots following SO 2 fumigation was stronger than the reduction in I4 CO 2 uptake.
