O3-exposed leaves protected new leaves against the effects of subsequent O3 exposure. Seedlings cultured in indoor ambient air for 3 weeks were transferred to a charcoal-filtered chamber. After 7 days, the newly developed leaves grew to a length of approximately 1 cm. A significant difference in the severity of foliar injury was observed for newly developed leaves with (left) and without (right) old leaves after exposure to 150 ppb O3 for 8 hours.
