Potato is the world’s most important non-cereal food crop, one of the major sources for humankind food. Conventional propagation asexual by tubers, can disseminate pathogens to new cultivation areas which can threatens the maintenance of genotypes of these specie. Ipomoea batatas as well, is a hard climate conditions plant, with a major role in food worldwide battle and have similar response to viruses or diseases In this work we analyzed varieties of Ipomoea batatas, 'Ro-Ch-M’, 'KSH’ and 'KSP1’, two varieties of Solanum tuberosum L. with purple flesh, 'Violet Queen’ and 'Purple Majesty’. The stydy compare the influences of gibberellic acid GA3, along with another two hormones, cytokinins (6-benzylaminopurine BAP), and α-naphthaleneacetic acid (NAA), the culture duration and response to tuberization of those varieties. Optimal proliferation was observed when shoots were cultured on MS medium that was supplemented with 1.5 mg/L GA3 and a variation of another two hormones. In this medium, the greatest number of shoots (4.1) and total number of nodes (12.2) per explant were observed.
