The small offer of healthy seedlings, however, the expansion of this activity. The presence of endophytic microorganisms such as Pseudomonas sp. represents an obstacle even for the evolution of heliconia tissue culture studies. Stem apices of Heliconia rauliniana were inoculated and analyzed in vitro to investigate the presence of endophytic microorganisms. An antibiotic analysis was also run for posterior microbiological control. The presence of Pseudomonas sp. and Klebsiella sp. in stem apices confirmed infection. Antibiotics such as chloramphenicol, cefotaxime and the association of both (chloramphenicol + cefotaxime) at... |
