dc.descriptionThe present research study is based on improving the viability and development of banana cv. Williams, which is essential for the propagation of this, this promote into an increase in the production of healthy seedlings, cost reduction and improvement in crop quality. The main objective of the research was to reduce the amount of phenols in in vitro explants of banana cv. Williams by using different antioxidants during the first phase of induction under laboratory conditions. The treatments used were: T1 (ascorbic acid), T2 (activated carbon), T3 EDTA (ethylene diamine tetraacetic acid), T4 (Control with Distilled Water) and T5 (Absolute control of direct seeding without pre-treatment). The variables studied: presence of phenols in the explants, development time and vigor of the explants, survival rate of the pre-treated explants. The information obtained from the variables was tabulated by Kruskal Wallis' analysis of variance, including its comparison of means (p <0.05). Regarding the results, the analyzed data showed highly significant differences (p=<0.0001) in terms of phenol reduction in banana explants, indicating that antioxidant treatments were successful in different intensities and ranges; two treatments were the ones that showed greater efficacy, T2 (activated carbon) and T4 (Control with Distilled Water), with a phenolyzation percentage between 50.42% and 66.46%, therefore the greatest success of explants came from these treatments, showing greater efficacy compared to the others, being the most optimal and at the same time allowed to move on to the next stage of multiplication.es_ES

dc.description.abstractEl presente estudio de investigación se fundamenta en mejorar la viabilidad y el desarrollo de los explantes de banano cv. Williams, lo cual es esencial para la propagación de este, esto se traduce en un aumento de la producción de plántulas sanas, reducción de costos y mejora en la calidad del cultivo. El objetivo principal de la investigación fue disminuir la cantidad de fenoles en explantes in vitro de banano cv. Williams mediante el uso de diferentes antioxidantes durante la primera fase de inducción en condiciones de laboratorio. Los tratamientos utilizados fueron: T1 (ácido ascórbico), T2 (carbón activado), T3 EDTA (Ácido etilen diamino tetra acético), T4 (Testigo con Agua Destilada) y T5 (Testigo absoluto de siembra directa sin pre-tratamiento). Las variables estudiadas: presencia de fenoles en los explantes, tiempo de desarrollo y vigor de los explantes, tasa de supervivencia de los explantes pre-tratados. La información obtenida de las variables, fue tabulada mediante el análisis de varianza de Kruskal Wallis incluyendo su comparación de medias (p <0.05). En lo referente a los resultados, los datos analizados mostraron diferencias altamente significativas (p=<0,0001) en cuanto a la reducción de fenoles en los explantes de banano, indicando que los tratamientos antioxidantes fueron exitosos en distintas intensidades y rangos; dos tratamientos fueron los que mostraron mayor eficacia, T2 (carbón activado) y T4 (Testigo con Agua Destilada), con un porcentaje de fenolización entre 50,42% y 66,46%, por ende el mayor éxito de explantes vinieron de estos tratamientos, mostrando mayor eficacia en comparación a los demás, siendo los más óptimos y a la vez permitieron pasar a la siguiente etapa de multiplicación.es_ES
