Abstract
PATINO TORRES, Carlos; HOYOS SANCHEZ, Rodrigo and AFANADOR KAFURI, Lucía. SELECTION AND in vitro REGENERATION OF SOMACLONES OF TREE TOMATO (Solanum betacea cav. Sendt) USING CULTURE FILTRATES OF Colletotrichum acutatum WITH PECTINASA ACTIVITY. Rev. Fac. Nac. Agron. Medellín [online]. 2007, vol.60, n.2, pp.3923-3937. ISSN 0304-2847.
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.
