Influence of weather conditions of crop on harvest quality and post-harvest behavior of pineapple guava fruit

Abstract

Las condiciones climáticas de cultivo, que definen las propiedades o atributos de los frutos de feijoa en la recolección, determinan también el comportamiento de los mismos durante la poscosecha. En este estudio se evaluó el efecto de las condiciones climáticas de cultivo en algunos atributos de calidad de la fruta en el momento de la cosecha, así como en su comportamiento durante el periodo poscosecha. Se consideraron dos predios situados en localidades diferentes del departamento de Cundinamarca - Colombia, localizadas a altitudes de 1.800 msnm y 2.580 msnm, en cada una de las cuales se marcaron 20 árboles y se realizó el registró de los parámetros climáticos en el periodo de desarrollo de los frutos hasta la cosecha, para dos periodos diferentes de producción. Se evaluaron periódicamente los parámetros de calidad en el periodo de desarrollo de los frutos hasta la cosecha, así como en el periodo poscosecha. En la poscosecha, los frutos diferenciados por localidad fueron almacenados a temperaturas de 5±1oC (87±5% HR) y 18±1oC (76±5% HR), con valoración de los parámetros de calidad cada 2 días. La conclusión del estudio fue que la calidad de los frutos en la cosecha y durante la poscosecha depende de las condiciones climáticas de cultivo. Los frutos producidos a altitud mayor tienen más sólidos solubles totales y mayor tamaño y peso, presentando en poscosecha menor pérdida de peso y menor firmeza y acidez. A mayor temperatura de almacenamiento los frutos presentaron más pérdida de peso y de firmeza, mayor contenido de azucares y menos durabilidad.

The weather conditions of crop, which define the properties or attributes of the feijoa fruits at the time of harvest, also determine the behavior of the same during post-harvest. In this study, the effect of the weather conditions of the crop on some fruit quality attributes at the harvest, as well as on its behavior during the post-harvest period, was evaluated. Two farms were considered located in different localities of the department of Cundinamarca - Colombia, located at altitudes of 1,800 masl and 2,580 masl, in each of which 20 trees were marked and the weather conditions registered during the development period of the fruits until the harvest, for two different periods of production. The parameters of quality in the period of development of the fruits until the harvest, as well as during the post-harvest period, were evaluated periodically. In postharvest, fruits differentiated by location were stored at temperatures of 5 ± 1oC (87 ± 5% RH) and 18 ± 1oC (76 ± 5% RH), with assessment of quality parameters every 2 days. The conclusion of the study was that the quality fruit in the harvest and during the post-harvest depends on the weather conditions of crop. Fruits produced at higher altitudes have higher content of total soluble solids, larger size and weight, presenting in post-harvest less weight loss and less firmness and acidity. At higher storage temperature, the fruits presented more weight loss and firmness, higher sugar content and less durability.
