Exposure of broad bean (Vicia faba L.) plants to 270 +/- 32 and 670 +/- 45 micrograms m 3SO{sub 2} for 1.5 hr daily between 40 and 85 days of their ages resulted in an increase in their transpiration rate, water saturation deficit, phenol content, and peroxidase activity and a decrease in protein content. With the increase in number of exposures of plants to SO{sub 2}, chlorotic and brown, necrotic visible injury signs were also developed in leaves. It was further noted that the magnitude of undesirable biochemical changes, which possibly helped in the formation of new pigment characteristic of necrotic tissue of SO{sub 2}-exposed plants, was not totally dependent on the pollutant concentration.
