Resumo: Papaya (Carica papaya L.) fruits are highly perishable due the fast ripening after harvest. The search for techniques that extend the shelf life and reduce the post-harvest losses is desirable. In this study, papaya 'Sunrise Solo' fruits were harvested in two ripening stages (green and ripe) and treated with the competitive ethylene antagonist 1-methycyclopropene (1-MCP) at concentrations of 0, 30, 90 or 270 nL L-1 for 12 h at 20ºC followed by storage at room temperature (20ºC) during eight days. Application of 1-MCP (90 or 270 nL L-1) delayed degreening decay. Green fruits treated with 1-MCP (270 nL L-1) presented higher firmness in relation to control fruits. 1-MCP did not affect the soluble solids of fruits. The respiration rate and ethylene production were lower in fruits treated with 1-MCP (90 or 270 nL L-1) in both ripening stages. 1-MCP extended the shelf life of green fruits from four to six days and the shelf life of ripe fruits from two to four days. The 1-MCP was efficient to delay the ripening of papayas extending their shelf life

A busca de técnicas que ampliem o período de conservação e reduzam as perdas pós-colheita é desejável. Mamões 'Sunrise Solo' foram colhidos em dois estádios de maturação (verde e maduro) e tratados com o antagonista competitivo do etileno 1-metilciclopropeno (1-MCP) nas concentrações de 0, 30, 90 e 270 nL L-1, durante 12 horas a 20ºC. Após o tratamentos os frutos foram armazenados em condições ambientais (20ºC) durante oito dias. A aplicação do 1-MCP (90 e 270 nL L-1) retardou a perda de coloração verde dos frutos e a incidência de podridões. Frutos verdes tratados com 1-MCP (270 nL L-1) apresentaram maior firmeza do que os frutos controle. O 1-MCP não afetou o conteúdo de sólidos solúveis dos frutos. A taxa respiratória e a produção de etileno foram reduzidas nos frutos tratados com 1-MCP (90 nL L-1 e 270 nL L-1) em ambos estádios de maturação. O 1-MCP (90 nL L-1 e 270 nL L-1) aumentou a vida de prateleira dos frutos do estádio verde de quatro para seis dias e dos frutos maduros de dois para quatro dias. Este bloqueador da ação do etileno mostrou-se eficiente para retardar o amadurecimento de mamões e aumentar sua vida de prateleira Universidade de São Paulo.
