The effects of progressively higher CO2 levels on the foliar antioxidant status were studied by growing soybean (Glycine max Merrill cv. Cresir) plants at decreasing distances from natural sources geothermal origin in central Italy. When compared with neighbouring controls grown under normal concentration (C), leaves 2 × C, 7 C and more than 20 showed a substantial reduction size ascorbate pool activity Cu,Zn-superoxide dismutase; both content ascorbic acid peroxidase declined recovered to control values C. titre glutathione disulfide activities reductase Mn-superoxide dismutase increased as ambient air. results obtained suggest that immanent risk dioxygen toxicity associated photosynthetic electron flow could be reduced presence high levels. On other hand, depending exposure regimes cell compartment considered, promote oxidative processes which cause GSH oxidation require an enhanced cellular ability scavenge superoxide anion hydrogen peroxide.
