Beauveria bassiana (balsamo) vuillemin as an endophyte in tissue 3 culture banana (Musa spp.) por Akello, J., Dubois, T., Gold, Cliford S., Coyne, Danny L., Nakavuma, J., Paparu, P.

“…Three screenhouse experiments were conducted to determine the ability of B. bassiana to form an endophytic relationship with tissue culture banana (Musa spp.) plants and to evaluate the plants for possible harmful effects resulting from this relationship. Three Ugandan strains of B. bassiana (G41, S204 and WA) were applied by dipping the roots and rhizome in a conidial suspension, by injecting a conidial suspension into the plant rhizome and by growing the plants in sterile soil mixed with B. bassiana-colonized rice substrate. …”
