The Mechanism of Oleocellosis in 'Fengji' Navel Oranges Induced by Mechanical Injury

Abstract:

Our goal was to evaluate how mechanical injury induced oleocellosis, and its discolouration and oxidative stress mechanism in Fengji Navel oranges (Citrus sinensis L. Osbeck) during previous storage. The results indicated that H₂O₂ content in mechanical treated fruit was higher than control. APX activity was higher than control during most of previous storage, but CAT, GR activities and ASA, GSH contents were lower than control, which showed GR activity and ASA, GSH contents might play an important rule in enhancing H₂O₂ to damage cell in mechanical treated fruit. Moreover, our study showed that chlorophyll content was enhanced, but total phenols content was not affected by mechanical during previous storage, which showed that discolouration was turning green but not browning at previous storage.
