Abstract
Physalis peruviana L. “aguaymanto” es una Solanacea muy apreciada en paises como Peru, Colombia y Ecuador debido a su alto valor nutricional y numerosas propiedades medicinales. Su cultivo tiene alta variabilidad debido a que se propaga por semillas, lo cual hace necesario mantener sus caracteristicas morfologicas y productivas homogeneas. una alternativa es la micropropagacion in vitro para, posteriormente, lograr su tecnificacion e industrializacion. Por lo expuesto, el objetivo de este trabajo fue inducir brotes y raices en hipocotilos y cotiledones de P. peruviana L. utilizando auxinas y citoquininas. Se realizaron nueve combinaciones entre las concentraciones de 2,4-D (0.25, 0.5 y 1.0 mg/l) y BAP (0.1, 0.25 y 1.0 mg/l), en la cual se introdujeron explantes de 20 dias de edad. El medio basal fue el de Murashige & Skoog complementado con sacarosa al 3%, fitagel (0.5%) y pH 6. Despues de 70 dias, luego de estar expuestos a fotoperiodo 16:8, se logro inducir la formacion de callos en todos los tratamientos y en ambos tipos de explantes. Ademas, en los hipocotilos hubo induccion de raices con la combinacion 0.1 mg/l de 2,4-D + 1.0 mg/l de BAP y en los cotiledones se indujeron raices con la combinacion 0.5 mg/L de 2,4-D + 1.0 mg/L de BAP, y tambien raices y brotes en la combinacion 1 mg/l de 2,4-D + 1.0 mg/l de BAP. Se concluye que los cotiledones favorecen el proceso de regeneracion de raices/brotes mejor que los hipocotilos.
