The present work aimed to evaluate the influence of concentrations of 6-benzylaminopurine (BAP) used in acclimatization of gloxinia (Sinningia speciosa Lood. Hiern). Concentrations of BAP (0.0; 0.5; 1.0 and 2.0 mg L-1) in vitro and substrates (vermiculite, plantmax®, and vermiculite+plantmax®) were tested for acclimatization in every possible combination. After in vitro inoculation, the material was transferred to a growth chamber with temperature of 26±1ºC and light intensity of 35 m mol m-2 s-1 for 16 hours, remaining under these conditions for 60 days. After that period, the plants obtained were transferred to pots containing substrates in a greenhouse. The evaluations were performed 120 days after cultivation. It were measured number of shoots, roots dry weight, above-ground dry weight, and number of flowers. On acclimatization, the best results for the variables were obtained with the use of the substrate Plantmax® or Plantmax®+vermiculite for plants originated from culture tissue.
