Two-way interactions indicated the significant effect of the
plant juice origin (Fig. 4); the juice of T. alexandrinum, followed
by M. crystallinum, supported the highest RMO populations
colonizing the endo-rhizosphere, not only in
homologous roots but also those nesting in all heterologous
plant roots. The ecto-rhizosphere is significantly the richer;
RMO did increase with the successive dilutions of plant juices.
Statistical analysis indicated that all tested plant juices, aside
from C. edulis, were able to support RMO in root spheres
indiscriminately
