Abstract

Chlorophyll concentrations in western wheatgrass, an important dominant species in the grasslands of the northern Great Plains of North America, exposed to controlled SO2 concentrations were examined. Concentrations of chlorophylls a and b were significantly decreased, without visible plant necrosis. Chlorophyll-a was more sensitive than chlorophyll-b. Sensitivity of chlorophylls to SO2 changed as the growing season progressed, indicating cumulative effects and interactions with normal senescence.
