Abstract

Ten open-top chambers were used to obtaine SO2 concentration-response relationships for growth in subterranean clover cv. ‘Trikkala’, and to study the associated sulphur accumulation. Four-week-old seedlings were exposed to 4, 41, 120, 255 or 515 nl l−1 of SO2 for 77 days, 4 h day−1. Response variables measured included leaf dry weight, stem weight, runner length, leaf number, average leaf weight, leaf: stem ratio and leaf sulphur concentration. Significant reductions in growth and changes in assimilate distribution occurred at 120 nl l−1 and higher concentrations; leaf sulphur concentration increased by ∼70 and 100% at 41 and 120 nl l−1, respectively.
