Ozone stress

Ozone pollution at the periphery of urban centers and industrial areas is responsible for significant plant productivity losses in both agricultural and forest areas. By examining the physiological responses at the plant leaf scale, it is theoretically possible to understand the mechanisms of alteration of photosynthesis in response to ozone pollution stress compared to other stressors . A research team specialized in plant ecophysiology just recently demonstrated that photochemical indices, detectable at a distance, are sensitive to ozone pollution stress in oak. These results, obtained thanks to the use of Ecotron climate chambers, pave the way for the development of remote sensing methods for monitoring the effects of this pollution on forests.
