Abstract
Influence of ambient temperature,exogenous ethylene of different concentrations(10～20 μL·L-1,50～80 μL·L-1)on MDA content,PPO and LOX activities of 'Bayuecui' peach fruit(Prunus persica) during CA storage(9%～11% CO2+9%～11% O2) and then 3 days shelf-life at 20℃ was studied.The results showed that the content of peach fruit increased with the days of storage at ambient temperature,the peaks of PPO and LOX activities were at 4 days of stoeage.The MDA content of peach fruit during CA storage increased when treated with exogenous ethylene.A higher MDA content appeared at the 60 days of storage when treated with 50~80 μl·L-1 exogenous ethylene.The MDA content of peach fruit in cold storage increased gradually with the time of storage,and its MDA content at the 60 days of storage was higher than that at the ambient temperature.The effects of exogenous ethylene on LOX and MDA were similar.The treatment of exogenous ethylene with 50～80 uL·L-1 concentration could suppress the PPO activity in the early storage period,while exogenous ethylene with 10～20 μL·L-1 concentration could reduce the PPO activity in the late period,however,the PPO activity with 10～20 μL·L-1 concentration appeared rise obviously after peach fruit was ripen at 20℃ for 3 days.Considering the comprehensive effects of different ethylene concentrations on MDA content,PPO and LOX activities of peach fruit during CA storage and shelf-life,treatment with 50～80 μL·L-1 exogenous ethylene was more effective in alleviating the cooling injury and controling the browning of peach fruit in low temperature storage.
