| Abstract: | The comparative influence of soil microorganisms, aerial contaminants and Bacillus subtilis on growth and potassium nutrition was studied in Zea mays and other cereals under aseptic growth conditions. Soil microorganisms, but not aerial contaminants, markedly modified root morphology and growth. Potassium uptake and translocation, measured by 86Rb as a tracer, were enhanced by growth in the presence of a soil inoculum although the relative influence on uptake and translocation varied from inoculum to inoculum. Similar metabolic changes were not found in seedlings inoculated with aerial contaminants. |
