Aminoethoxyvinylglycine (AVG, 124 mg L? 1 , Retain®) was sprayed 28 DBAH, as a commercial control treatment. Fruit maturation was delayed by increasing 1-MCP concentration. 1-MCP at concentrations ? 150 mg L? 1 delayed by six and 15 days the time for the fruit to reach the harvest firmness of 71.1 N and 66.7 N, respectively, compared to untreated fruit. Skin color changes (red color development and background degreening) were inhibited by increasing 1-MCP concentrations up to 300 mg L? 1 . The reduction of ethylene synthesis, and the loss of flesh firmness and starch content occurred by increasing 1-MCP concentrations up to 98.2, 134.5 and 182.3 mg L? 1 , respectively. The AVG treatment delayed ethylene production and skin red color development at harvest more markedly than the highest concentration of 1-MCP (300 mg L? 1 ). However, both treatments (AVG and 1-MCP at 300 mg L? 1 ) had late harvested fruit (28 days after spraying 1-MCP) with percentage of skin red color below 40%. The results show that 1-MCP delays maturity, but concentrations ?135 mg L? 1 do not improve its efficacy on preserving flesh firmness while might inhibit skin red color development in ?Cripps Pink? apples. aApples aPostharvest physiology aPostharvest technology aPostharvest treatment aMaçã aMalus Domestica aPós-Colheita aRegulador de Crescimento aAgendamento de colheita aCor da pele aCripps Pink aFirmeza de carne aInibição da ação do etileno aPré-colheita de 1-MCP1 aARGENTA, L.
