The aim of this work was to test techniques to reduce microbial contamination in the phases of introduction and establishment of the in vitro cultivation of Bambusa vulgaris through two experiments. The first experiment was carried out in a completely randomized design using a factorial arrangement (pre-treatment of nodal segments using or not a solution of Derosal 500 SC® and Chloramphenicol × culture medium with half or full concentration of salts × culture medium with presence or absence of sucrose × culture medium with presence or absence of Plant Preservative MixtureTM). In a second experiment, carried out in a completely randomized design, the effect of different fungicides associated to Chloramphenicol in a liquid culture medium was tested. It was possible to verify that the isolated effects of the pre-treatment by immersion of the nodal segments in a solution of 4 mL L-1 of Derosal 500 SC® and 200 mg L-1 of Chloramphenicol for 30 minutes and explants placed in a sucrose-free medium reduced fungal contamination. In the second experiment, the treatment that reduced fungal contamination corresponded to explants placed for seven days in a liquid medium with half the concentration of salts, sucrose-free, with 2 mL L-1 of Plant Preservative MixtureTM and with 4 mL L-1 of  Derosal 500 SC® and 200 mg L-1 of Chloramphenicol.Downloads
