Activated charcoal is recommended to be added to nutrient media, used in crops of plant tissues, to the growth and development of some types of explants, but also its role of absorbing toxic compounds present in aseptic environments, which cause necrosis of inoculated tissues. . The main purpose of this study was to assess the influence of three concentrations of activated carbon (0.5 g/l, 1 g/l, 2 g/l) added to the MS culture medium, on the formation and root development of two varieties of sweet potato (DK 19/1 and DK 19/5). ). A bifactorial experience was initiated, the analyzed factors being: variety and culture environment. Determinations were made on the following parameters: root length, fresh root weight and dry root weight. Based on the obtained results, an optimal rooting was observed, without callus formation, ensuring a higher percentage of capacity at acclimatization of sweet potato seedlings from in vitro to in vivo.
