Inducción de la brotación en tubérculos de Ipomoea batatas mediante una mezcla de oligogalacturónidos bioactivos para su establecimiento in vitro
Tuberous roots of sweet potato, belonging to clone CEMSA 78-354, coming from banks of seeds and collected, keeping in mind their sanity and uniformity in the size, were used. They were transferred to laboratory under semicontrolled conditions and placed in glass flasks with 300 mg.l -1 of tap water (control treatment) and in flasks with the some volume of water and different pectimorf concentration (5, 10, 15 and 0 mg.l -1 ). At different time the following indicators: number of sprouts per tuber, length of sprouts and number of buds per sprouts. Evaluated indicators were achieved with the use of 15 mg.l -1 Pectimorf overcoming those reached by the control treatment.Key words: buds, Pectimorf, sprouts, sweet potatoSe emplearon raíces tuberosas de boniato pertenecientes al clon CEMSA 78-354, procedentes de bancos de semillas, las cuales fueron seleccionadas teniendo en cuenta su sanidad y uniformidad en el tamaño. Las mismas fueron trasladadas al laboratorio a condiciones semicontroladas y se colocaron en frascos de cristal con 300 ml de agua corriente (control) y en frascos con la misma cantidad de agua y diferentes concentraciones de Pectimorf (5, 10, 15 y 20 mg.l -1) . Se evaluaron en diferentes momentos los siguientes indicadores: número de brotes por tubérculo, longitud de los brotes y número de yemas por brote. De manera general, con el empleo de 15 mg.l -1 de Pectimorf se obtuvieron los mejores resultados en los indicadores evaluados, superando los alcanzados por el control.Palabras clave: boniato, brotes, Pectimorf, yema
