Se utilizaron filtrados de cultivo de Colletotrichum acutatum, agente causal de la antracnosis del tomate de árbol, para la selección in vitro de variantes somaclonales de ésta planta con resistencia potencial a la enfermedad. El filtrado, utilizado a varias concentraciones, demostró ser un agente de selección efectivo cuando se integró al medio de cultivo, pues causó niveles elevados de mortalidad de los explantes comparado con los tratamientos sin filtrado. Igualmente, se estudió el efecto de la benziladenina (BA ó BAP) sobre la respuesta organogénica de explantes de tejido foliar de tomate de árbol.Culture filtrates of Colletotrichum acutatum, causal agent of the anthracnose disease in tree tomato, were used for the in vitro selection of somaclonal variants with potential resistance to this disease. Culture filtrates used at different concentrations, showed to be an effective agent of selection when they were mixed with the growth media. The findings indicated a high level of mortality for the explants growing on the ammended media as compared with these growing on non ammended one. The effect of the benziladenina (BA ó BAP) on the organogenic response of leaf explants of tomato tree was also studied.
