BIOSIS COPYRIGHT: BIOL ABS. The emission of reduced volatile sulfur compounds from twigs of Norway spruce (Picea abies (L.) Karst.) was measured in the field by cryosampling and gas chromatographic analysis. Trees were growing in the Erzgebirge (E-Germany) at Oberbarenburg and at the Kahleberg and at a third stand in NW-Bavaria (S-Germany). Emission rates were also measured for Scotch pine (Pinus sylvestris L.) and Blue spruce (Picea pungens Engelm.) at the Kahleberg. Twigs still attached to the trees were enclosed in a flow-through gas exchange cuvette. H2S was detected as the predominant reduced sulfur compound emitted from the twigs. The mean H2S emission rate from twigs of Norway spruce varied between 0.04 pmol kg-1 dw s-1 at Wurzburg and 6.21 pmol kg-1 dw s-1 at the Kahleberg. Comparing different species at the Kahlebera, the mean H2S emission rate was almost the same from twigs of Norway spruce (6.2 pmol kg-1 dw s-) and Blue Spruce trees (5.9 pmol kg-1 dw s-1) but it was approximately 18 ti
