Abstract
Information on input of acidifying compounds like SO2 and NOx is necessary to understand effects of acidification. The uptake on NO and NO2 respectively was studied on seedlings and shoots of Scots pine (Pinus sylvestris L.). Experiments were conducted both in laboratory (NO and NO2 respectively) and in the field (NO2) under light and dark conditions. In all three cases there was a linear relationship between the uptake rate and the NOx-concentration. The uptake follows a diurnal pattern i.e. the uptake rate was strongly correlated with the stomatal movements. Uptake rates were converted to deposition rate and the results showed that field exposure with NO2 gave the higher deposition rate.
