The effect of airborne sulfur dioxide on ornamental plants was examined by comparative greenhouse fumigation of various foliage plants, landscape ornamentals, and flowering ornamentals at 0, 0.5, 1.0, and 2.0 ppM SO/sub 2/. Selected SO/sub 2/ levels allowed placement of plants into very low, low, intermediate, high and very high susceptibility categories based on foliar injury. Foliar symptoms included marginal and interveinal necrosis and enhanced chlorosis. Flowers generally were not affected by SO/sub 2/ exposure, but occasionally were the most susceptible organ. 11 references, 1 table.
