Response of oilseed Brassica cultivars to ozone

Abstract

Cultivars of four oilseed Brassica species were exposed to acute levels of ozone (0.31 or 0.47 μL L−1) at the seedling stage. Brassica hitra ’BHL-926’ was the most sensitive to ozone followed by B. juncea ’Newton’ and B. rapa ’Torch.’ Brassica napus seedlings exhibited very little foliar injury (0 – 4%) after 24 h exposure to 0.31 μL L−1 ozone. Key words: Ozone, foliar injury, rapeseed, mustard
