Treatment with 1-MCP: an alternative to extend storage in plums harvested with advanced maturity
Maturity at harvest is a determining factor in fruit storage potential, especially in such perishable species as plums (Prunus salicina L.). However, harvest´s logistics is very complex, and a large percentage of fruits are harvested at a more advanced stage of maturity than the optimum recommended for long storage. Treatment with 1-MCP has shown to be effective in reducing the post-harvest deterioration rate of Japanese plums, but the effectiveness of this treatment may be reduced in late harvested fruit. The aim of this trial was to determine the efficiency of treatment with 0.4 μL L-1 of 1-MCP in Larry Ann plums harvested at 4 different maturity stages. The results showed that the treatment was effective in reducing the ripening rate of the fruit at all harvest timings. The duration of this effect and the number of parameters affected decreased as harvest was delayed. In maturity stage 1 (M1, ~62 N) and maturity stage 2 (M2, ~58 N), 1-MCP delayed ethylene production rate during shelf life after 30, 40, and 50 days of storage at 0 ºC and reduced loss of flesh firmness, and acidity. At the maturity stage 3 (M3, ~50N) 1-MCP delayed ethylene production rate during shelf life after 30 and 40 days of storage at 0 ºC and maintained higher flesh firmness values. In fruit harvested at the maturity 4 (M4, ~35 N), 1-MCP did not affec ethylene production rate, but reduced loss of flesh firmness during shelf life, supporting the hypothesis that the treatment has a direct inhibitory effect on softening enzymes, independent of ethylene.

La madurez en el momento de cosecha es un factor determinante del potencial de almacenamiento de los frutos, principalmente en especies tan perecederas como las ciruelas (Prunus salicina L.). Sin embargo, la logística de cosecha es muy compleja y un gran porcentaje de frutos se cosecha con un estado de madurez más avanzado al óptimo recomendado para larga conservación. El tratamiento con 1-MCP ha mostrado ser efectivo en reducir la tasa de deterioro poscosecha de ciruelas japonesas, pero la efectividad de este tratamiento puede verse reducida en frutos de cosechas tardías. El objetivo de este ensayo fue determinar la eficiencia del tratamiento con 0,4 μL L-1 de 1-MCP en ciruelas Larry Ann cosechadas en 4 estados de madurez diferentes. El tratamiento redujo la tasa de maduración de los frutos en todas las cosechas. La duración de este efecto y el número de parámetros afectados disminuyó a medida que se retrasó la cosecha. En el estado de madurez 1 (M1, ~62 N) y el estado de madurez 2 (M2, ~58 N), el 1-MCP retrasó la tasa de producción de etileno durante la vida en estante después de 30, 40 y 50 días de almacenamiento a 0 ºC y redujo la pérdida de firmeza y de acidez. En el estado de madurez 3 (M3, ~50 N) el 1-MCP retrasó la tasa de producción de etileno durante la vida en estante después de 30 y 40 días de almacenamiento a 0 ºC y mantuvo mayores valores de firmeza. En frutos cosechados con madurez 4 (M4, ~35 N) el 1-MCP no afectó la producción de etileno, pero redujo la pérdida de firmeza durante la vida en estante, apoyando la hipótesis de que el tratamiento tiene un efecto inhibitorio directo sobre las enzimas del ablandamiento, independiente del etileno. O estádio de maturação na colheita é um fator determinante no potencial de armazenamento dos frutos, principalmente em espécies tão perecíveis como as ameixas (Prunus persica L.). No entanto, a logística da colheita é muito complexa e uma grande porcentagem de frutas é colhida com um estado de maturação mais avançado do que o ideal recomendado para conservação prolongada. O tratamento com 1-MCP vem demonstrando ser eficaz na redução da taxa de deterioração pós-colheita das ameixas japonesas, mas a eficácia desse tratamento pode ser reduzida em frutos de colheitas tardias. O objetivo deste estudo foi determinar a eficiência do tratamento com 0,4 μL L-1 de 1-MCP em ameixas 'Larry Ann' colhidas em 4 estádios de maturação. Os resultados mostraram que o tratamento com 1-MCP foi eficaz na redução da taxa de amadurecimento dos frutos em todos os momentos. A duração desse efeito e o número de parâmetros afetados diminuíram com o atraso da colheita. Nos estádios de maturação 1 (M1,~62 N) e estádios de maturação 2 (M2,~58 N), a aplicação de 1- MCP atrasou a produção de etileno durante a vida de prateleira após prazo de 30, 40 e 50 dias de armazenamentoa 0ºC e reduziu a perda de firmeza de polpa e acidez. No estado de maturação 3 (M3, ~50N), o 1-MCP atrasou a produção de etileno durante a vida de prateleira após 30 e 40 dias de armazenamento a 0ºC e manteve valores mais altos de firmeza. Nos frutos colhidos no maturação 4 (M4,~35 N), o tratamento com 1-MCP não afetou a produção de etileno, mas reduziu a perda de firmeza de polpa durante a vida de prateleira, apoiando a hipótese de que o tratamento tem um efeito inibitório direto sobre as enzimas relacionadas ao amolecimento da polpa dos frutos independente do etileno.
