Shelf life of peaches treated with 1-methylcyclopropene Vida útil de pêssegos tratados com 1-metilciclopropeno

Peaches [Prunus persica (L.) Bastch] present reduced post-harvest shelf life, partially, due to their high respiratory rate and fast ripening. These processes are related to ethylene production, as well as its action. Peaches, cv. Aurora-1, were picked at two different ripening stages (mature green...

Peaches, cv. Aurora-1, were picked at two different ripening stages (mature green and ripe) and treated with 1-methylcyclopropene (1-MCP), the ethylene's competitive antagonist, at concentrations of 0, 100, 300 and 900 nL L-1 for 12 hours at 25ºC.
