          Abstract

          Abstract Colombia is the country with the greatest genetic diversity in passion fruit species, some of which are cultivated on an area of approximately 13,673 ha. Each variety must be planted at a suitable altitude under optimal conditions to obtain the best quality. Regarding plant nutrition, potassium has the greatest influence due to the effect of its application on the yield increase, ascorbic acid content and lifecycle to harvest. Adequate water increases the percentage of the marketable quality and amount of fruit juice, and the use of rootstocks does not significantly change the fruit quality. Ensuring a pollination of the flowers in cultivation is decisive for the fruit formation and its juice content. The species differ greatly in their quality, as purple passion fruit (Passiflora edulis f. edulis) is a fruit that develops the highest content of ascorbic acid, while sweet calabash (P. maliformis) forms the maximum amount of phenols and total antioxidant activity. The maturation and ripening of passion fruit is determined by the skin coloration, during which the Brix grades and the maturity index increase and the titratable acidity diminishes. Fruits harvested early in physiological maturity and with unripe peel color can be treated with ethylene in post-harvest, matching fruits that ripened in the plant. More research is needed in the improvement of the quality of the Passifloraceae. Giant granadilla (P. cuadrangularis) and sweet calabash have been studied less than banana passion fruit (P. tripartita var. mollissima), purple passion fruit, yellow passion fruit and sweet granadilla (P. ligularis). The last three species are the most exported fruits in the country.

          RESUMEN Colombia es el país de mayor diversidad genética en especies de pasifloras, algunas de las cuales se cultivan abarcando aproximadamente 13,673 ha. Cada variedad debe ser sembrada en sitio y piso térmico apto para desarrollar su calidad óptima, igualmente debe ser cultivada con las mejores prácticas para aprovechar su potencial. En la nutrición, es el potasio el que muestra mayor influencia ya que aumenta el rendimiento y el contenido de ácido ascórbico y acorta el tiempo para cosechar. Suministro suficiente de agua aumenta el porcentaje de calidad de fruto mercadeable, así como el jugo del fruto, mientras que el uso de patrones no influye significativamente en la calidad de los frutos. Garantizar una polinización de las flores en cultivo es decisivo para la formación del fruto y el jugo. Las especies difieren mucho en su calidad, siendo la gulupa (Passiflora edulis f. edulis) la que desarrolla un contenido más alto en ácido ascórbico, mientras la cholupa (P. maliformis) se destaca por el máximo en fenoles y actividad antioxidante total. La maduración de los frutos de las pasifloráceas está bien determinada por la coloración de la cáscara, durante la cual los grados Brix y el índice de madurez aumentan, y la acidez titulable disminuye. Los frutos cosechados tempranamente en madurez fisiológica y con cáscara de poca coloración pueden ser tratados con etileno en poscosecha igualando a los frutos madurados en planta. Más investigación es necesaria para el mejoramiento de la calidad de las pasifloráceas, siendo la badea (P. cuadrangulares) y la cholupa las menos estudiadas, en comparación con la curuba (P. tripartita var. mollissima), la gulupa, el maracuyá y la granadilla (P. ligularis), de las cuales las últimas tres están dentro de las frutas más exportadas del País.

            Sugars, ascorbic acid, total phenolic content and total antioxidant activity in passion fruit (Passiflora) cultivars

            The levels of sugars, ascorbic acid, total phenolic content (TPC) and total antioxidant activity (TAA) were determined in fruit juices from seven passion fruit (Passiflora spp.) cultivars: P. edulis cultivars Purple, Frederick, Yellow, Pink, P. edulis f. flavicarpa, P. maliformis and P. quadrangularis (we also tested this cultivar's mesocarp).
