Cultivares de maracujá-roxo desenvolvidas regionalmente podem contribuir para o aumento da produção de frutos de qualidade atendendo às necessidades do mercado. Objetivou-se avaliar os frutos de maracujá-roxo, obtidos em sistemas de cultivo convencional e orgânico. Os frutos foram colhidos em estágio de maturação comercial (casca totalmente roxa) e analisados quanto à caracterização físico-química, centesimal, compostos bioativos e capacidade antioxidante. Os frutos analisados apresentaram maiores valores médios para o rendimento de polpa e sólidos solúveis em sistema convencional, que foram de 49,04% e 13,86 °Brix. O valor calórico energético foi de 45,95 kcal/100 g em sistema orgânico, indicando que o consumo do fruto “maduro” pode ser realizado a fim de suprir as necessidades energéticas diárias. As polpas dos frutos de maracujá-roxo estudados demonstraram serem fontes importantes de componentes bioativos, com respaldo aos elevados valores médios para ácido ascórbico e polifenóis extraíveis totais em ambos os sistemas de cultivo. Palavras-chave: Passiflora edulis Sims; manejo; sólidos solúveis; compostos fenólicos.   Postharvest characterization of purple passion fruits cultivated in conventional and organic system   ABSTRACT: Regionally developed purple passion fruit cultivars can contribute to the increase in the production of quality fruits, meeting marked needs. The objective of this study was to evaluate the purple passion fruits, obtained in conventional and organic cultivation systems. The fruits were harvested at the stage of commercial maturation (totally purple peel) and analyzed for characterization of the physicochemical, centesimal composition, bioactive compounds and antioxidant capacity. The analyzed fruits showed higher average values ​​for pulp yield and soluble solids in a conventional system, which were 49.04% and 13.86 °Brix. The caloric energetic value was 45.95 kcal/100 g in organic system, indicating that the consumption of the “ripe” fruit can be carried out in order to meet the daily energy needs. The pulps of the purple passion fruit studied proved to be important sources of bioactive components, supported by the high mean values ​​for ascorbic acid and total extractable polyphenols in both farming systems. Keywords: Passiflora edulis Sims; management; soluble solids; phenolic compounds.

Purple passion fruit (Passiflora edulis Sims f. edulis) is a tropical juice source. The goal of this project was to evaluate photosynthetic and physiological variability for the crop with the hypotheses that landraces contain the diversity to adapt to higher elevation nontraditional growing environments and this is dependent on specific parameters of ecological adaptation. A total of 50 genotypes of this crop were chosen from divergent sources for evaluations of their eco-physiological responses in two equatorial locations at different altitudes in the Andes Mountains, a center of diversity for the species. The germplasm included 34 landraces, 8 commercial cultivars, and 8 genebank accessions. The two locations were contrasting in climates, representing mid and high elevations in Colombia. Mid-elevation valleys are typical regions of production for passion fruit while high elevation sites are not traditional. The location effects and variables that differentiated genotypes were determined. Results showed statistically significant differences between locations and importance of physiological parameters related to photosynthesis and water use efficiency. Some landraces exhibited better water status and gas exchange than commercial types. Parameters like maximum photosynthesis, points of light saturation and compensation, darkness respiratory rate, and apparent quantum yield varied between genotype groups. The landraces, commercial types, and genebank entries also differed in content of carotenoids and chlorophylls a and b. Meanwhile, photosynthesis measurements showed that altitudinal difference had an effect on genotype-specific plant growth and adaptation. An important conclusion was that landraces contained the diversity to adapt to the new growing environment at higher altitudes.
