Abstract
Inoculation with rhizobia ofM. sativa plants grown either in the laboratory on nitrogen-free agar and soil-agar slopes or in field experiments, decreases in all cases the concentration of Mo in plant shoots and increases that of Rb, while differences in the concentration of several elements with atomic numbers between 17 and 42 could also be identified by X-ray fluorescence. These elemental alterations depend on the fixation induced either by inoculation or by the effective indigenous rhizobial population of each growth medium and are not caused by rhizosphere pH alterations but seem to be directly related to the induced biological nitrogen fixation.
