The establishment of the in vitro culture of Guadua angustifolia nodal segments presents as the main problem the contamination by microorganisms, causing biological and economic losses. This research was developed at the National Center for the Study of the bamboo-Guadua bamboo, in municipality of Cordoba, Quindio and it was financed by the Regional Autonomous Corporation of the Quindio (C. R. Q). Six treatments were evaluated for the disinfection of the explants of guadua bamboo with sodium hypochlorite (NaClO) in concentrations of 2% and 3 %, each one of them in time of application of 5, 10, and 15 minutes , the explants were planted in the culture medium Murashige and Skoog medium supplemented with 6-BAP at a rate of 3mg L-1. The percentage of sprouting was also evaluated. The best result of disinfection and budding was obtained with the NaClO to 2% for 15 minutes.
