Fruit Characterization of Prunus serotina subsp. capuli

Abstract

Prunus serotina is divided into five subspecies. Among these, P. serotina subsp. capuli, commonly known as capuli, is native to Central and South America. Its fruits are big, sweet, and consumed by locals in various forms, with the Ecuadorian Andes region providing the best fruit forms of capuli. The objective of this study was to characterize a collection of different genotypes of capuli’s fruit, and their endocarps, found growing in the wild in the Chimborazo, Tungurahua, and Cotopaxi provinces of Ecuador. The fruits were characterized for weight (11.7–50.3 g), diameter (12.4–21.7 mm), height (11.4–19.7 mm), and soluble solids content (SSC) (13.4–27.6 °Brix) across two years. Similarly, the endocarps’ diameters (7.5–12.2 mm) and heights (8.1–13.6 mm) were measured. Significant differences were found for all the fruit and endocarp variables studied. A multivariate analysis showed that all the fruit and endocarp size characteristics, except SSC, were positively correlated with each other within a season. No clear population differentiation was seen among the genotypes from different provinces, suggesting a lack of clear morphological differentiation. The future breeding and selection of a capuli with superior, commercial, large fruit and a high SSC shows great potential.

Social Perception of the Ecosystem Services of Prunus serotina subsp. capuli in the Andes of Ecuador

“…Due to the diversity of ES identified by locals in the three study areas of the CO, CH, and TU provinces, there are opportunities to conserve specific sites in the central Andes of Ecuador in order to optimize the supply of ES for provisioning, regulating, supporting, and, above all, cultural services which focus on a cultural re-evaluation. This is because Prunus serotina plays an important role in the life of Ecuadorian people [81].…”

Physicochemical Properties of Geographical Indication (GI) Sweet Cherries in China and Their Influencing Factors of Cultivar, Climate Type, and Soil Condition

“…However, their MI values are significantly higher, with Tianbao at 38.56 ± 1.82 and Qinzhou at 35.22 ± 0.30, which can be attributed to their lower titratable acidity. A series of studies confirmed that the SSC and TA of cherries mainly depend on cultivars [58,59]. Therefore, it can be seen that taking SSC, TA, and MI into account is more comprehensive and reasonable than only detecting the SSC of cherries to measure the fruit's degree of ripening.…”
