Fourteen cultivars of soybean [ Glycine max (L.) Merr.] from maturity groups 0 through VI were exposed to 30 and 70 pphm ozone for 1.5 hours to determine differences in cultivar sensitivity. Cultivar ‘Hark’ was the most susceptible, whereas ‘Hood’ was the most tolerant to ozone injury. ‘Hawkeye’ was the most sensitive cultivar at 70 pphm and among the least sensitive at 30 pphm, whereas ‘Chippewa 64’ was relatively tolerant at 70 pphm but among the most sensitive at 30 pphm. Ozone symptoms ranged from chlorotic and/or necrotic fleck and pigmented lesions to upper surface bleaching and bifacial necrosis of the leaves.
