Abstract:
‘Gala’ apples (Malus domestica Borkh.cv.‘Gala’) were used as materials to test the effects of Harvista (the active ingredient is 1-methylcyclopropene，1-MCP) sprayed 7 days before harvest on fruit quality，especially texture changes of ‘Gala’ apples during harvest and cold storage (the clean water was used as a blank control，and ethephon was used as positive control).In order to provide a new technology for regulating fruit quality after harvest.The results showed that Harvista reduced the preharvest fruit drop，maintained the titratable acid and soluble solid content of the fruit，and inhibited the respiration rate and ethylene production rate of the fruit during cold storage.Harvista also reduced the activities of amylase，pectin methylesterase，and β-galactosidase in the first 60 days and the activities of polygalacturonase and cellulase in the first 90 days during cold storage，thus delayed the decrease of starch，protopectin and cellulose content，and inhibited the increase in soluble pectin content in the first 90 days during cold storage,while ethephon showed the opposite effects.The regulation of ethylene before harvest effectively changed the harvest and storage quality of ‘Gala’ apples，and spraying the ethylene inhibitor-Harvista 7 days before harvest can maintain the texture of the fruit during cold storage and delay fruit softening.
