“Evaluación fisiológica de dos especies de semillas y siete variedades de gramíneas en el campus Salache, cantón Latacunga, provincia de Cotopaxi 2022”

The research project physiological evaluation of two species of seeds and seven varieties of grasses in the campus Salache, Latacunga canton, Cotopaxi province 2022, whose specific objectives were to evaluate the physiological potential of two species of barley (Hordeum vulgare) and five species of wheat (Triticum aestivum l); determine which genotype has the best performance in terms of physiological quality, in response to the tests used. The genotype with the best performance in terms of physiological quality in response to the tests used, the methodology used was experimental. A completely randomized design (CRD) was used, with seven treatments and four replications, giving a total of twenty-eight experimental units, the statistical analyses were carried out using the R studio programmed. From the physiological tests it is concluded that T4 (vivar wheat 2020) presented the best physiological performance with a standard germination percentage of 90.86%, with an average of 30.61%, in emergence speed index 50.75%, for accelerated aging, 80.22%, for the cold test, the parameter of electrical conductivity gave off the least number of leached ions with 16. 65 µS, regarding tetrazolium it presents 92.5% and the moisture content was 22.6%, without having significant statistical differences in relation to the other evaluated lines, it is recommended to use the seed T4 (wheat vivar 2020) for field since it has the best physiological performance surpassing the other evaluated seeds.The research project physiological evaluation of two species of seeds and seven varieties of grasses in the campus Salache, Latacunga canton, Cotopaxi province 2022, whose specific objectives were to evaluate the physiological potential of two species of barley (Hordeum vulgare) and five species of wheat (Triticum aestivum l); determine which genotype has the best performance in terms of physiological quality, in response to the tests used.

El proyecto de investigación evaluación fisiológica de dos especies de semillas y siete variedades de gramíneas en el campus Salache, Cantón Latacunga, provincia de Cotopaxi 2022, cuyos objetivos específicos fueron evaluar el potencial fisiológico de dos especies de cebada (Hordeum vulgare) y cinco de trigo (Triticum aestivum l); Determinar cuál es el genotipo que presenta el mejor desempeño en cuanto a su calidad fisiológica, como respuesta a las pruebas utilizadas. La metodología utilizada fue la experimental. Se utilizó un diseño completamente al azar (DCA), con siete tratamientos y cuatro repeticiones, dando un total de veinte y ocho unidades experimentales, los análisis estadísticos fueron realizados utilizando el programa R studio. De las pruebas fisiológicas se concluye que el T4 (trigo vivar 2020) presentó el mejor desempeño fisiológico con un porcentaje de germinación estándar de 90.86%, con un promedio de 30.61%, en índice de velocidad de emergencia 50.75%, para envejecimiento acelerado, el 80.22%, para la prueba de frío, el parámetro de conductividad eléctrica desprendió menor cantidad de iones lixiviados con 16.65 µS, referente a tetrazolio presenta el 92.5% y el contenido de humedad fue de 22.6%, sin tener diferencias estadísticas significativas en relación a las otras líneas evaluadas, se recomienda utilizar la semilla T4 (trigo vivar 2020) para campo ya que tiene el mejor desempeño fisiológico superando a las demás semillas evaluadas.
