crop quality and nutritive value ( USEPA, 2015 ). Sensitivity to O 3 varies both within and among species. In general, plants that have higher stomatal conductance ( g s ), which allows a greater flux of O 3 into the leaf ( Reich and Amundson, 1985

Chartzoulakis et al. (1993) reported that A. deliciosa seedlings showed poor control of transpiration even though there was a reduction in stomatal conductance (g s ) and suggested that this species has poor epidermal control of water loss through leaky

supplemental CO 2 . Morison and Gifford (1983) reported that the stomatal conductance ( g S ) of plants decreases under elevated CO 2 , whereas the internal concentration of CO 2 increases and net assimilation rate is either unaffected or increased ( Mott
