Sixteen varieties of rooted chrysanthemum cuttings were exposed to concentrations of sulfur dioxide (SO/sub 2/) or ozone (O/sub 3/) that might occur in highly polluted ambient air. None of the varieties was particularly sensitive to SO/sub 2/ or O/sub 3/. At 4.5 ppm SO/sub 2/ for 4 hours, only 5 varieties showed even slight damage, and at 0.30 ppm O/sub 3/ for 3 hours only two varieties were slightly damaged. By comparison, at these concentrations zinnia, geranium, and pinto bean would be injured by SO/sub 2/ and tobacco, tomato, pinto bean, squash, and cucumber by O/sub 3/.
