Plants of Pisum sativum L. were exposed to sulfur dioxide and ozone to determine whether changes in stomatal aperture during exposures were associated with leaf injury. It was concluded from these studies that pollutants play a significant role in producing changes in stomatal aperture. The strongest indication that stomatal response was associated with the amount of leaf injury was the occurrence of stomatal closure and reduced injury 1) in expanding leaves, 2) in plants grown under high soil moisture stress, and 3) in plants exposed to pollutants early and late in the light period. 86 references, 8 figures, 14 tables.
