SUMMARYCaulogenic induction was studied using mature seeds as initial explants. Four concentrations of BAP (0, 3, 5 and 7 mg L -1 ) in the mediums MS, B5 and SP were evaluated for the callus formation. The callus formed in the previous stage was used for the caulogenesis, evaluating the effect of two concentrations of ANA (0.1 and 0.5 mg L -1 ), maintaining constant the BAP (1.0 mg L -1 ) and the nutritious media from which they came. In the callus formation, the best results were obtained with 7 mg L -1 of BAP (73%) when using the medium B5; differing significantly from MS. For the caulogenesis, the medium SP produced the highest values in formation of shoots (78%) differing significantly from the media B5 and MS. BAP-ANA's combination (1.0-0.1 mg L -1 ) was more appropriate for the formation of shoots (62%), although without statistically differing from the other combination. In conclusion, the callus formation is directly related with the concentration of BAP and the nutritious media used. Also, the concentration of BAP from which the callus and the combinations of BAP and ANA come, for the caulogenesis, do not influence significantly in the formation of adventitious shoots, contrary to the used nutritious media.Key words: Eucalyptus globulus, caulogenesis, callugenesis, auxins, citokinins. RESUMENSe estudió la inducción caulogénica utilizando semillas maduras como explantos iniciales. Para la callogénesis se evaluaron cuatro concentraciones de BAP (0, 3, 5 y 7 mg L -1 ) en los medios MS, B5 y SP. Para la caulogénesis se utilizaron los callos formados en la etapa anterior, evaluando el efecto de dos concentraciones de ANA (0,1 y 0,5 mg L -1 ), manteniendo constante el BAP (1,0 mg L -1 ) y el medio nutritivo del cual provenían. En la callogénesis los mejores resultados se obtuvieron con 7 mg L -1 de BAP (73%) al utilizar el medio B5, difiriendo significativamente de MS. Para la caulogénesis, con el medio SP se obtuvieron los valores más altos de formación de brotes (78%) difiriendo significativamente de los medios B5 y MS. La combinación de BAP-ANA (1,0-0,1 mg L -1 ) resultó más apropiada para la formación de brotes (62%), aunque sin diferir estadísticamente de la otra combinación. Se concluye que la callogénesis está directamente relacionada con la concentración de BAP y el medio nutritivo utilizado. Además, la concentración de BAP del cual provienen los callos y las combinaciones de BAP y ANA para la caulogénesis, no influyen significativamente en la formación de brotes adventicios, a diferencia del medio nutritivo utilizado.
