Cultivars of four oilseed Brassica species were exposed to acute level
s of ozone (0.31 or 0.47 muL L-1) at the seedling stage. Brassica hirt
a 'BHL-926' was the most sensitive to ozone followed by B. juncea 'New
ton' and B. rapa 'Torch.' Brassica napus seedlings exhibited very litt
le foliar injury (0 - 4%) after 24 h exposure to 0.31 muL L-1 ozone.
