Blackberries play an important role in human nutrition, due to the elevated content of certain bioactive compounds including ascorbate, anthocyanins, phenolic acids, carbohydrates, and proteins. Blackberry Rubus glaucus from Colombian Andes has a high demand on regional and international markets and there is much interest in its cultivation to increase the com mercial offer. In four blackberry producing municipalities of Cundinamarca province, fruits were harvested for different quality tests based on the availability of hydric resources in the zone and their influence on fruit characteristics according to the precipitation of each zone, since the crops did not have an irrigation system. The variables, such as size, fresh weight, tex ture, pH, titratable total acids (TTA), total soluble solids (TSS), and color were evaluated to compare the quality of the fruits between the municipalities, finding that fruits from Silvania had the greater size but, in turn, were the least consistent. El Colegio zone presented the sweetest fruits and together with Pasca had the highest acidity percentage. The color of Pasca and Silvania fruits was the most attractive for commercialization parameters. These parameters, even when management and agro-climatic conditions between municipalities were very similar, allows knowing the positive attributes and determine the factors that need to be improved and to project on a short-term future productions acceptable on the international market.
Albion is a strawberry (Fragaria x ananassa Duch.) plant variety that belongs to the Rosaceae family, which is notable in Colombia because of its vitamin content and organoleptic characteristics. Fruits of this variety from four municipalities (Mosquera, Guasca, Sibate, Facatativa) in the province of Cundinamarca were evaluated. Significant differences in physical and chemical characteristics were detected between fruits of the four areas. For the physical parameters, fruits from Mosquera were notable because of their large size and biomass content. The specific chemical qualities of the fruits from Guasca make them important for the industry and processing. The fruits from Sibate had an acceptable content of citric acid and, at the same time, a high content of sugars, qualities that result in high acceptance for products in a fresh market. Finally, the fruits from Facatativa were characterized by intense colors and attractiveness to final consumer. Because of the varying conditions of each municipality, the fruits presented different strengths, so the implementation of new harvesting technologies is recommended so that all producers in the province can achieve the same high-quality characteristics in order to obtain worldwide recognition.
RESUMEN: El objetivo de esta investigación fue determinar diferencias de dimorfismo sexual de las características de labios de hombre y mujeres mestizos colombianos a través de análisis fotogramétrico. Se evaluaron fotografías frontales de 120 individuos mestizos sin alteraciones congénitas o adquiridas de los labios, tomadas en relación 1:1. A través del uso de puntos antropométricos en la vista frontal, se evaluaron las dimensiones: Grosor del Labio Superior (Sn-Stms), Grosor del bermellon superior (Stms-Ls), Grosor del Labio Inferior (Stmi-Sml), Grosor del bermellon Inferior (Stmi-Li) y Ancho bicomisural (Chd-Chi), con la ayuda del software J image (NIH). El análisis estadístico utilizó la prueba U Mann-Whitney usando el software SPSS 17.0, para determinar diferencias entre los dos sexos en todas las variables. No se encontraron diferencias estadísticamente significativas en la longitud del bermellón del labio superior (Stms-Ls) ni en la longitud del bermellón del labio inferior (Stmi-Li). Se encontraron diferencias estadísticamente significativas (p<0,001) en Grosor del Labio Superior (Sn-Stms), Grosor del Labio Inferior (Stmi-Sml) y Ancho bicomisural (Chd-Chi). Estas medidas fueron mayores en individuos mestizos de género masculino. Existe dimorfismo sexual en el ancho bicomisural, longitud de labio superior e inferior en Colombianos Mestizos.
