Leaf length, crown width, Chl a/b, net photosynthetic rate, stomatal conductance, and transpiration rate were significantly reduced at 100 and 200 mm 3(O 3) m -3. Measurements of growth, leaf chlorophyll (Chl) content, and gas exchange parameters were made before and/or after O 3 exposure. ChinaĢ-year-old seedlings of Metasequoia glyptostroboides were grown in open top chambers and exposed to four ozone concentrations (charcoal-filtered air, CF 50, 100, and 200 mm 3 m -3) for 25 d.
