Differential responses of the antioxidant defence system and ultrastructure in ...
Queirós, Filipa; Rodrigues, José A.; Almeida, José M.; Almeida, Domingos P. F.; Fidalgo, FernandaChanges in lipid peroxidation and ion content and the possible involvement of the antioxidant system in salt tolerance at the cellular level was studied in a potato (Solanum tuberosum L.) callus line grown on 150 mM NaCl (salt-adapted) and in a non-adapted line exposed to 150 mM NaCl (salt-stressed). Salinity reduced the growth rate and increased lipid peroxidation in salt-stressed line, which remained unaltere...
Antioxidant properties and fruit quality during long-term storage of “rocha” pe...
Silva, Filipe J. P.; Gomes, Maria Helena; Fidalgo, Fernanda; Rodrigues, José A.; Almeida, Domingos P. F.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 disord...
