The crop of quinoa has gained relevance during the last decade in different parts of the world, due to its adaptability to difficult edaphic and climatic conditions and the great nutritional potential of its seeds. However, climate change scenarios are increasingly adverse, so the search for strategies that favor greater adaptability of quinoa to areas where other crops fail to adapt is a scientific priority. For this reason, a systematic review was carried out, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis methodology, with documents published on Scopus and Clarivate Web of Science databases. This methodology describes the diversity of fungi that favors symbiosis and the services offered by arbuscular mycorrhizal fungi in the physiological activity of the quinoa plant, in addition to their interaction with the edaphic conditions, mainly related to nitrogen and phosphorus. The results identified a projection of interest in research related to the symbiosis between these two organisms, but a very limited advance in relation to the study that has been developed around the microbiological activity of quinoa in the soil.

The great diversity of quinoa allows variations in physiological, production, and compositional performance. This study aimed to evaluate six quinoa cultivars through the physiological and nutritional responses of their seeds. Different dynamics were identified in the plant height, and the number of leaves was adjusted to sigmoidal models with R2 greater than 0.97 and 0.77, respectively. The chlorophyll concentration varied through the phenological phases, as did the maximum quantum yield of photosystem II. Differences in the quinoa grains were found between CIEL*a*b* colorimetric coordinates and protein, carbohydrate, and fat contents. In this sense, quinoa cultivars manifest different biological behaviors associated with their genetic nature. Besides, a relationship between cultivars and seed composition was recognized. These results will allow researchers to study other significant differences between the precocity expressed by the Puno, Nariño, and Titicaca cultivars and those with a longer phenological cycle such as the Soracá cultivar.

El presente estudio es resultado de una investigación de enfoque cualitativo con énfasis en el método de investigación acción educativa. Su fin es interpretar la forma en que los saberes etnobotánicos generan fortaleza en la competencia del entorno vivo, la enseñanza y formación en Ciencias Naturales en estudiantes 1 ° a 3° grado de primaria en la Institución Educativa Las Mercedes, sede Cazadero del municipio de Nunchía –Casanare y la Institución Educativa Técnico Agrícola Sede Las Minas del municipio de Boavita–, Boyacá, Colombia. La intervención se realiza teniendo en cuenta los conocimientos etnobotánicos de las dos poblaciones participantes y desde la cual se estructura un conjunto de talleres que responden a tres componentes fundamentales: la etnobotánica, la vinculación con aspectos propios del entorno vivo y de concepción biológica, así como a la conservación ecológica. Se evidencia el papel fundamental que ejerce la utilización del contexto en el proceso de enseñanza, así como la importancia que tiene la familia en el proceso educativo con los aportes de conocimiento ancestral y de acercamiento al saber científico.

La Universidad publica los resultados de los trabajos de los docentes que, previa evaluación, han demostrado tener éxito en la formación académica de nuestros estudiantes, como un incentivo para que continúen mejorando en sus procesos didácticos y cada vez sean más exitosos en su labor.
