The alterations of the lipid metabolism and the uncertainty at the moment of selecting beneficial foods to the human body lead to the investigation of omega fatty acids. The study is based on the evaluation of the effect of three preparation methods of chía seed, before getting the oil through two extraction methods and the characterization of the lipid fraction of chia seed (Salvia hispánica L.) from Colta-Ecuador. The oil yield of the conditioned seeds showed statistical differences. Regarding the extraction method, the differences were highly significant, the use of ether in the Soxhlet equipment showed the superiority in the oil performance in a relation of approximately 2:1 versus immersion in hexane. The presence and the content of fatty acids was determined by the use of a gas chromatograph with FiD detector Agilent Technologies 5975C brand, fatty acids were separated with a cap...

Las alteraciones del metabolismo lipídico y la incertidumbre al seleccionar alimentos benéficos para el organismo humano, conducen a la investigación de los ácidos grasos omega. El estudio evalúa el efecto de tres métodos de acondicionamiento de la semilla de chía (Salvia hispánica L.), previo a la extracción del aceite mediante dos métodos y, la caracterización lipídica de semillas provenientes de Colta-Ecuador. El rendimiento de aceite de las semillas acondicionadas presentó diferencias estadísticas. En cuanto al método de extracción, las diferencias fueron altamente significativas, la utilización de eter en Soxhlet mostró mayor rendimiento en una relación aproximada de 2:1 frente a la inmersión en hexano. La presencia y contenido de ácidos grasos se determinó mediante el uso de un cromatógrafo de gases con detector FID marca Agilent Technologies 5975C, los ácid...

El cultivo de la uva (Vitis vinífera L.) está incrementándose en el trópico seco y los valles interandinos del Ecuador. Sin embargo, la calidad del racimo y las bayas del cv. ‘Marroo Seedless’ cultivado en los Valles requieren mejorarse para competir con la fruta importada. Para ello, en plantas de 8 años se realizaron tres experimentos, en los que se evaluaron dosis y épocas de aplicación de GA3 (pre y posfloración), raleo manual de frutos del racimo y anillado de la rama con el fin de incrementar el tamaño de los racimos y las bayas. Se utilizó un diseño experimental de bloques completos al azar con cuatro repeticiones. Se evaluó el tamaño y peso del racimo y bayas, número de bayas por racimo y sólidos solubles totales. Los resultados muestran que la aplicación de GA3 en prefloración (10 ppm) incrementa el largo y diámetro polar de los racimos, mientras que el may...

Genus Vaccinium groups plants like shrubs that grows in the highlands of the Andes Mountains. Its fruits are characterized by their antioxidant and nutritional properties. The objective of this paper review was to understand the effect of endophytic and associated microorganisms with the rhizosphere of Vaccinium spp. Wild Vacciunium species present low genetic variability, in comparison with cultivated species that present high variability. Therefore, wild species must be domesticated in order to achieve permanent production in various locations along the year. Domestication of this plant could be achieved by stablishing physiological plant system, determining its edaphoclimatic requirements and analysis of interactions with the plant. One of the main problems of the Vaccinium genus is fungal diseases, such as Botrytis sp. and Hemileia vastatrix. However, other endophytic and rhizosphere...

The infestation of the root system by nematodes (Meloidogyne incognita) and Fusarium solani to the rootneck hinders the production of tree tomato (Solanum betaceum Cav.), an Andean native fruit consumed in Ecuador and other countries. This paper evaluates the potential of different Ecuadorian Andean Solanaceae species (Solanum auriculatum, Solanum asperolanatum, Solanum arboreum and Nicotiana glauca), such as tree tomato rootstocks towards Fusarium and nematode resistance through controlled inoculation trials. The experimental design used was complete randomized in factorial arrangement with three factors. The variables were: fungus incubation time, incidence and lesion size, increase in nematode population, plant height increase and plant fresh weight. The most promising results for an extended open field evaluation were N. glauca (no incidences of Fusarium and 0.36 times increase in ne...
