Resumo: | Eucalyptus is the most important plantation forest species in Brazil. Wilt and canker caused by Ceratocystis fimbriata on eucalyptus were first reported in 1998 in plantations of an E. grandis × E. urophylla hybrid in southern Bahia, Brazil. This work aimed at studying the reaction of different eucalyptus genotypes after inoculation with C. fimbriata isolates, in order to find a possible source of resistance. The study included four isolates of Ceratocystis collected from eucalyptus in different regions. One disc of fungal mycelium with 1-cm-diameter (from colonies growing for 10 days on malt extract agar medium-MEA) was inoculated on the stem of thus injured eucalyptus plants (six months old). A cotton wool moistened with sterile distilled water was wrapped with plastic film. Control plants were inoculated with discs of MEA without fungal colonies. The inoculated plants were kept in a greenhouse. Wilt symptoms were observed 90 days after inoculation. The seedlings were cut in the longitudinal direction of the stem in order to observe the colonization of fungus in the plant xylem. We tested twenty eucalyptus genotypes, but only five showed resistance to all isolates of Ceratocystis, belonging to different species of Eucalyptus: E. urophylla (C2 and C9), E. grandis (C3), E. saligna (C6 and C13) Most E. gramdis genotypes were more susceptible to all four fungal isolates. These results support future studies related to eucalyptus resistance to Ceratocystis. |
