juices as culture media for RMO (Table 1). Obtained plant
juices (crude juice diluted to 1:40, v/v) were used to prepare
plating agar media. Making use of the surface–inoculated
plates technique, RMO populations in the various root
spheres, developed on homologous and heterologous plant
juice-based culture media compared to all the tested reference
culture media, were estimated in terms of cfu.
