Ten cultivars of azalea (Rhododendron sp.) were exposed to 0.30 ± 0.05 ppm ozone (590 ± 100 μg/m3) for 8 hours at various times during the summer. 'Louise Gable', 'Delaware Valley White' and 'Rose Greeley' were significantly more susceptible than were 'Stewartstonian', 'Fedora', 'Orange Beauty', 'Hino-crimson', 'Hershey Pink', 'Rosebud', and 'Springfield Crimson'. Neither rate of gas exchange nor stomatal frequency was correlated with degree of visible injury induced by ozone.
