Abstract:: Taking ‘Hongyan’ strawberry fruit as material,packaging with plastic wrap，the dynamic variation of reactive oxygen and protective enzyme activities were studied during ageing process under different temperature (4 ℃,25 ℃) treatment.The results showed that in storage process of strawberry fruit under the conditions of normal temperature and low temperature，LOX activity and H2O2 content increased first and then decreased.O?[TX-*4]2 production rate，electric conductivity，MDA content increased continuously.SOD activity remained little change，POD activity increased continuously，activities of CAT and APX increased first and then decreased.LOX activity，O?[TX-*4]2 production rate，contents of H2O2 and MDA，electric conductivity under low temperature storage were all lower than these under normal temperature storage，also the peaks of these reactive oxygen were late under low temperature storage compared with these under normal temperature storage.In conclusion，reactive oxygen accumulation and lipid peroxidation intensified ageing of strawberry fruit，low temperature storage delayed the process of strawberry fruit ageing by weakening reactive oxygen accumulation and lipid peroxidation extent.
