| Abstract |
Stomatal conductance and transpiration were measured on normally-irrigated and water-stressed field-grown cotton (Grossypium hirsutum) exposed throughout the growing season to a gradient of ozone (O3) concentrations. Environmental conditions during the growing season strongly affected stomatal responses and yield redutions due to O3 exposure. Maximum stomatal conductance and transpiration decreased with increased O3 concentration both in NI and WS treatments. Reductions in conductance and transpiration in O3-stressed plants were attributed to inhibition of photosynthesis by O3, leading to accumulation of CO2 in intercellular spaces. |
