Abstract

Persea americana, cv. Hass has become an important crop in Colombia due to increased exports to European markets; however, the avocado is a climacteric fruit sensitive to chilling injury, reducing its shelf-life and affecting commercialization abroad. This research aimed to evaluate the effect of 1-methylcyclopropene, ethylene, and intermittent warming on chilling injury and postharvest behavior of avocado cv. Hass. Five treatments were evaluated: Control; Intermittent warming cycles of 4 days at 2 °C + 1 day at 18 °C; Intermittent warming cycles of 7 days at 2 °C + 1 day at 18 °C; 1-methylcyclopropene, and ethylene. The fruits were stored for 29 days at 2 °C and then up to 14 days in the shelf-life period. The intermittent warming treatment 4-days cycles reduced chilling injuries. However, this treatment increased weight loss, respiration, epidermal color index, and electrolyte leakage during the storage period at 2 °C. Intermittent warming showed that Hass avocado fruit ripens faster, regardless of the application of ethylene in the shelf-life period. The results indicated that intermittent warming reduced the chilling injury, the treatment with 1-methylcyclopropene delayed ripening but it is not recommended for avocado cv. Hass when stored at 2 °C because the chilling injury is not reduced.

鳄梨果实采后行为及冷害研究。哈斯用1-甲基环丙烯、乙烯和间歇升温处理

美洲波斯，cv。由于对欧洲市场的出口增加，哈斯已成为哥伦比亚的一种重要作物;然而，牛油果是一种对冷害敏感的更年期水果，减少了它的保质期，影响了国外的商业化。研究了1-甲基环丙烯、乙烯和间歇增温对牛油果冷害及采后行为的影响。哈斯。评价5个处理:对照;2℃下4天+ 18℃下1天的间歇升温周期;2℃下7天+ 18℃下1天的间歇升温周期;1-甲基环丙烯和乙烯。在2℃条件下贮藏29天，贮藏期最长可达14天。以4 d为一个周期的间歇加热处理可减轻冻伤。然而，在2°C的储存期间，这种处理增加了体重减轻、呼吸、表皮颜色指数和电解质泄漏。间歇升温表明，无论在保质期内使用乙烯，哈斯鳄梨果实成熟得更快。结果表明，间断性加温可以减轻牛油果的冷害，1-甲基环丙烯处理可以延缓牛油果的成熟，但不推荐使用。当储存在2°C时，由于冷伤不减少。

期刊介绍： La Revista Facultad Nacional de Agronomía Medellín (RFNA), de la Universidad Nacional de Colombia, Sede Medellín, Facultad de Ciencias Agrarias, es una publicación científica editada desde el año 1939, en formato impreso y digital y de acceso abierto desde la web —sin costo para autores y lectores—. Está orientada a investigadores que crean conocimiento disciplinar y multidisciplinar que articula la ciencia y la tecnología para hacer más productivo el campo a nivel empresarial y de economía campesina. La Revista tiene como objetivo divulgar resultados de investigación mediante artículos originales, inéditos y arbitrados (peer review) de carácter científico que respondan a preguntas específicas y que proporcionen sustento y pruebas a una hipótesis, en aspectos relacionados con las Ciencias Agronómicas, Producción animal, Ciencias Forestales, Ingeniería Agrícola, de Alimentos y otras afines que contribuyan a la solución de los limitantes del agro a nivel nacional, regional e internacional. La Revista recibe y publica, sin ningún costo, artículos en idioma inglés de investigación, revisión, reseñas y cartas al editor. Desde el 2017 la periodicidad de publicación es cuatrimestral, se publican tres números al año con circulación nacional e internacional, en los siguientes períodos: Enero - Abril Mayo - Agosto Septiembre - Diciembre This journal does not charge APCs or submission charges.
