Exposure to moderate concentrations of tropospheric ozone impairs tree stomatal response to carbon dioxide
(2011) In Environmental Pollution 159(10). p.2350-2354- Abstract
- With rising concentrations of both atmospheric carbon dioxide (CO2) and tropospheric ozone (O-3), it is important to better understand the interacting effects of these two trace gases on plant physiology affecting land-atmosphere gas exchange. We investigated the effect of growth under elevated CO2 and O-3, singly and in combination, on the primary short-term stomatal response to CO2 concentration in paper birch at the Aspen FACE experiment. Leaves from trees grown in elevated CO2 and/or O-3 exhibited weaker short-term responses of stomatal conductance to both an increase and a decrease in CO2 concentration from current ambient level. The impairement of the stomatal CO2 response by O-3 most likely developed progressively over the growing... (More)

The impairement of the stomatal CO2 response by O-3 most likely developed progressively over the growing season as assessed by sap flux measurements. Our results suggest that expectations of plant water-savings and reduced stomatal air pollution uptake under rising atmospheric CO2 may not hold for northern hardwood forests. under concurrently rising tropospheric O-3.
