Results Collected information on the distribution spots of wild Vanilla sp. in Colombia allow the identification and visit to nine places located in multiple departments (Table 2). Collected plant roots belonged to wild individuals without signals of disease. By sequencing ITS regions (data not shown), done by following the protocols of the Molecular and Cell Biology Lab of the Universidad Nacional – Medellín, it was possible to identify inoculated fungi that belong to typical endophyte genus of orchids and other plants (Picture 1). It was not possible the identification of V-10 and V-13 isolates due to repeated DNA contaminations. In Table 3 are observed the net values for each one of the biomass variables. After validating the assumptions, results indicate significant differences in: plant height (P = 0.0002), root length (P = 0.0213), root mass (P = 0.0173) and aerial mass (P = 0.0431); while
for leaf area there were no differences (P = 0.1148).
