The study provided an overview of the dynamics of growth, water uptake and water use of two tropical C4 forage grasses: Napier grass (Pennisetum purpureum) and Brachiaria hybrid cv. Mulato II. This in combination with the observations of leaf rolling scores suggested that Napier grass and Mulato fall respectively into contrasting “water spending/water saving” models of water use. As such, Napier grass might be targeted for areas with intermittent and short periods of drought, whereas Mulato II might be a better option for areas with longer drought spells.

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.

El siguiente texto es un comentario general al proyecto de ley que modica la actual normativa sobre protección de datos personales, la Ley 19.628 de 1999. Se busca destacar las modicaciones más importantes, junto con la nueva normativa propuesta, y examinar sus eventuales efectos y falencias.

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.
