N2 - Open-top fumigation chambers were used to study the effects of SO2 exposure on the barrel medic (Medicago truncatula cv. Paraggio). Plants were exposed for 4 hr/day, 7 days/week for 72 days to mean SO2 concentrations of 0.004, 0.041, 0.120, 0.255 or 0.515 μl/l. Final growth response curves are presented for shoot, leaf and stem dry weights, shoot length and numbers of leaves, flowers and branches. Increased SO2 concentrations caused a proportionate decrease in growth parameters, but a proportionate increase in foliar sulfur concentration. Medics growing in mixed pasture in newly industrializing areas with moderate or high SO2 concentrations may require more intensive management intervention.
