The effects of mycological media and temperature on mycelial growth and spore production of three fungal pathogens recently reported on Ricinodendron heudelotii were investigated. The pathogens were identified on the basis of the ITS sequences of their ribosomal DNA as Pestalotiopsis microspora (isolate PMHP_109L), Lasiodiplodia theobromae (isolate LTHP_110L) and Fusarium oxysporum (isolates FOBR_164S, FOBR_049L and FOHP_121L). The radial growth (mm/day) of the fungi and conidia concentrations (number of conidia/ml of suspension) were assessed on three culture media: potato dextrose agar (PDA), malt extract agar (MEA) and V8 juice agar (V8). All media were suitable for the growth of L. theobromae while V8 juice agar supported the fastest mycelial growth rate in P. microspora ( mm/day). |
