Resumo(s)
Free radical scavenging activity and the content of ascorbic acid and
glutathione were investigated during long-term storage of the pear (Pyrus
communis L. ‘Rocha’) fruit harvested at different maturity stages, stored in air
or under controlled atmosphere and subjected to postharvest treatments with
diphenylamine (DPA) and 1-methylcyclopropene (1-MCP). Harvest maturity
had a significant effect on storage disorders, fruit firmness, soluble solids
content and acidity. Differences in ascorbate content and free radical scavenging
activity at harvest did not persist during storage. Controlled atmosphere
and DPA strongly reduced the incidence and severity of browning
disorders and superficial scald, whereas 1-MCP provided the most effective
control. Neither DPA nor 1-MCP affected the free radical scavenging activity
