Enraizamiento in vitro de Dioscoreas sp.

Abstract

El presente estudio se realizó en el Laboratorio de Cultivo de Tejidos Vegetales de la Universidad de Córdoba en el año 2000 con el objetivo de evaluar el efecto del ácido naftalenacético (ANA) en el medio de cultivo sobre el enraizamiento in vitro de tres cultivares de ñame (Dioscorea sp.). Se estudió el efecto de cuatro concentraciones del regulador de crecimiento (0, 0.3, 0.6 y 0.9 mg/1) sobre tres cultivares de ñame (Diamantes-22, 003 y 005). Se empleó un experimento trifactorial con diseño aleatorio y 20 repeticiones; cada unidad experimental estuvo conformada por un recipiente de vidrio que contenía el medio de cultivo y el explante (segmento nodal). Las variables consideradas fueron número y grosor de raíces, oxidación del medio de cultivo y producción de callo. Los resultados indicaron que tanto la hormona como el genotipo tuvieron efecto sobre todas las variables consi­deradas en el estudio y que la interacción fue importante (P
