The effects of gaseous ozone on the growth of green mold (Penicillium digitatum) and the activity of antioxidant enzymes (superoxide dismutase, catalase and ascorbate peroxidase) in the peel of artificially inoculated tangerine (Citrus reticulate Blanco cv. Sai Nam Pung) fruit were examined. Ozone (200 mu L L-1) was applied for 0 (control), 2, 4 or 6 h to inoculated tangerine fruit. Exposing fruit to ozone for 4 and 6 h delayed disease incidence and reduced severity. Scanning electron microscopy confirmed that exposing fruit to ozone for 4 and 6 h reduced growth of fungi on the fruit peel. The activities of superoxide dismutase, catalase and ascorbate peroxidase were increased after ozone fumigation and remained significantly higher than those of the control fruit through three days of storage at 25 degrees C. Throughout the experiment, fruit qualities in all treatments were not affected by ozone exposure and no phytotoxicity occurred in fruit exposed to high doses of ozone. (C) 2011 Elsevier B.V.
