Abstract:
Field surveys for symptoms of foliar injury in a regional airshed that is influenced by a number of point sources of SOx, NOx and hydrocarbons, combined with foliar and soil sulfur analyses, confirmed earlier results that Saskatoon serviceberry (Amelanchier alnifolia Nutt.) cv. Smokey can be used as a biological indicator of chronic sulfur dioxide exposures, in the presence of other phytotoxic air pollutants such as ozone.
