Altitude as a determinant of fruit quality with emphasis on the Andean tropics of Colombia. A review
Due to global warming, the highlands of the tropics have become more important for planting fruit trees. The climate at high altitudes is mainly characterized by decreased temperatures and increased solar radiation. A systematic literature review using four bibliographic databases revealed 22 studies that determined fruit quality at two altitudes. With increasing altitude, duration of fruit development was prolonged, and, in most cases, higher fresh weights and sizes were found; however, fruit firmness decreased. The intensity of the fruit color increased because of greater radiation in high areas. Mostly, the total soluble solids of the fleshy fruits augmented with altitude, probably because of an increase in photosynthesis with higher solar radiation. The total acidity did not show a clear trend with increasing elevations. At higher altitudes, the content of antioxidants (mainly phenolics) increased in the fruits, especially in the epidermis as a reaction to the increasing ultraviolet (UV) light. Physiological disorders in the fruits included sunburn and damage caused by low temperatures. Different species and varieties react differently to the conditions of highlands, depending on their origin and whether climatic conditions are optimal for a specific fruit tree. There are no positive effects on fruit quality when altitude is at the limit or above the recommended range for the fruit species.

Debido al calentamiento global, las zonas altas de los trópicos han ganado importancia para la siembra de los frutales. El clima en estas áreas se caracteriza principalmente por tener bajas temperaturas y mayor radiación solar. Mediante una revisión de literatura sistemática en cuatro bases de datos bibliográficas se encontraron 22 estudios que determinaron la calidad de los frutos evaluada en mínimo dos altitudes. A mayor altitud el desarrollo del fruto se prolongó y en la mayoría de los casos, se encontró un mayor peso fresco y tamaño, sin embargo, la firmeza del fruto disminuyó. La intensidad del color del fruto aumentó debido a la mayor radiación en zonas altas. En la mayoría de los casos, los sólidos solubles totales de frutos jugosos se incrementaron con la altitud, probablemente, por el aumento de la fotosíntesis debido a la mayor radiación solar, mientras que la acidez total no mostró una tendencia clara con el incremento de la elevación. Con la altitud ascendente aumentó el contenido de los antioxidantes (principalmente compuestos fenólicos) en los frutos y, especialmente, en su epidermis, como reacción al aumento de luz ultravioleta (UV). Dentro de los desórdenes fisiológicos en los frutos se destacan los golpes de sol y los daños por bajas temperaturas. Las especies y variedades reaccionan de forma diferente a las condiciones de las zonas altas, dependiendo de su origen, y si las condiciones climáticas están dentro de las óptimas para este frutal. No se detectan efectos positivos sobre la calidad del fruto cuando la altitud está en el límite o por encima del rango recomendado para la especie frutal.
