Abstract/Contents:"Plant damage has been observed in New Jersey when elevated concentration of sulfur dioxide, ozone, peroxyacetylnitrate, or bisulfite-addition product (possibly aldehyde) occur in the ambient air. Certain plant species can be cited as particularly sensitive to each of the pollutants. At present ozone appears to be the principal air pollutant from the point of view of a number of plant species affected and the frequency of occurrences of phytotoxic levels. The extent of damage to a plant by a particular pollutant in any given year depends not only on the presence of a source for that pollutant and of plant susceptible to it, but also on the existence of meteorological factors that lead to air stagnation. Turfgrasses representing several genera and species were exposed for 6 hours to an atmosphere containing ozone (0.23-0.30 ppm) or sulfur dioxide (0.75-1.80 ppm). Response to either pollutant varied with the grass fumigated. Generally, bentgrass and annual bluegrass were most sensitive to 03; Bermudagrass and Zoysia were most resistant; and perennial ryegrass, Kentucky bluegrass, and red fescue were intermediate in their response. Symptoms of ozone toxicity were, typically, bleaching and necrosis of the leaf blade, except for pigmented stipples in red fescue. Red fescue and bentgrass were most sensitive to SO2; bluegrass and ryegrass were intermediate; and Bermudagrass and Zoysia were resistant. Sulfur dioxide toxicity consistently resulted in necrosis of the terminal portion of the leaf blade."
