Caracterización morfológica de pasto King Grass “morado” (Pennisetum purpureum), en las condiciones edafoclimáticas de Babahoyo

This research was carried out with the purpose of morphologically describing the "purple" King Grass (Pennisetum purpureum), under the agro-ecological conditions of the Babahoyo canton. Morphological diversity was analyzed in a sample size of 16 individuals located within the Faculty of Agricultural Sciences of the Technical University of Babahoyo located in Babahoyo province of Los Ríos. To evaluate the variability of phenotypic characteristics of the King Grass pasture, adapters used for other studies of the same nature were adapted. As results, it was possible to show that there are no phenotypic differences in the evaluated ecotypes of "purple" King Grass (Pennisetum purpureum), since none of the variables exceeded a Cv> 50%, indicating that the species has little variability. Regarding the correlation coefficient, the results show a relationship between the evaluated variables, where it was possible to determine that there are variables that are related such as: the weight of the leaf with the height of the plant with a value of 0.63; Likewise, a relationship between leaf width and stem diameter was evidenced with a value of 0.59. On the other hand, the analysis also shows a strong relationship between dry weight and wet weight with a value of 0.92.

Esta investigación se realizó con la finalidad de Describir morfológicamente el King Grass “morado” (Pennisetum purpureum), bajo las condiciones agroecológicas del cantón Babahoyo. Se analizo la diversidad morfológica en un tamaño de muestra de 16 individuos situados dentro de Facultad de Ciencias Agropecuarias de la Universidad técnica de Babahoyo situado en Babahoyo provincia de Los Ríos. Para evaluar la variabilidad de características fenotípicas del pasto King Grass se adaptaron caracterizadores utilizados para otros estudios de la misma índole. Como resultados se pudo evidenciar qué no existen diferencias fenotípicas en los ecotipos evaluados de King Grass “morado” (Pennisetum purpureum), ya que ninguna de las variables superó un Cv > a 50%, lo que indica que la especie tiene poca variabilidad. Con respecto al coeficiente de correlación, los resultados muestran relación entre las variables evaluadas, en donde se pudo determinar que existen variables que se relacionan como: el peso de la hoja con la altura de la planta con un valor de 0.63; De igual forma se evidencio relación entre ancho de hoja con diámetro de tallo con un valor de 0.59. Por otro lado, en el análisis también se muestra una fuerte relación entre peso seco y peso húmedo con un valor de 0.92.
