Abstract
We have investigated the presence of endophytic fungi associated with rose plants (Rosa hybrida) in Colombia. Endophytic fungi were isolated from healthy leaves of ten ornamental roses plants from gardens cultured in malt extract, peptone, yeast extract agar plates (MPY). We sampled 560 leaves fragments, 56 per sample. Endophytic fungi comprised 92 isolates (16.4%); of these isolates, 41 were classified as sterile mycelium (without reproductive structures that allowed their identification), 31 isolates were identified to genus or to species, and 20 isolates could not be identified at all. The identified endophytic fungi were as follow: Nigrospora oryzae, Aureobasidium spp, Acremonium spp. The fungi Nodulisporium sp, Gliocladium virens, Cladosporium sp, Alternaria sp, Phoma sp and Chaetomium globosum were represented by one isolate each. Since the endophytic fungi are known for their capacity to produce metabolites with biological activity, it is possible that the microorganisms found in this study have potential as antagonist of rose pathogens.
