Abstract
SUMMARY Arabidopsis thaliana (L.) Heynh. was exposed to various concentrations of SO 2 during almost the entire life cycle. No negative effects of SO 2 on shoot biomass production were observed. There was a linear relation between the deposition of SO 2 and the atmospheric SO 2 concentration. Sulphur accumulated substantially in the shoots upon SO 2 exposure. SO 2 was either oxidized to sulphate or converted into extra organic sulphur compounds in a sulphate to organic sulphur ratio of 3:1, independently of the atmospheric SO 2 concentration. Exposure to SO 2 resulted in an increase in water soluble non‐protein sulphydryl content and a slight increase in the amount of glucosinolates, but both of these play a minor role as sinks for the excess sulphur. The ratio of total nitrogen to total sulphur decreased upon SO 2 , exposure as a result of the increased sulphate content. The organic nitrogen to organic sulphur ratio did not change upon SO 2 exposure, indicating no changes in the composition of sulphur‐containing compounds.
