Summary
Combined inoculation of Rhizobium meliloti and Azospirillum brasilense Cd to seedlings of Medicago sativa grown in large petri dishes on sterile agar increased the number of nodules significantly but the effects depended on the concentrations of Azospirillum in the medium. The stimulating effect is probably due to the production of indole acetic acid (IAA) by Azospirillum since pure IAA mixed to the agar also led to higher numbers of nodules. An increase in nodule number was also found with soybean grown in soil under nonsterile conditions upon repeated inoculation with Azospirillum. The strain used and other A.brasilense strains produced considerable amounts of IAA when cultivated in N-containing nutrient solution whereas release from A. lipoferum strains was very low. A time course showed that most production of IAA occurred after the end of the logarithmic growth phase. The results indicate that rhizosphere bacteria may play a role in nodulation of legumes through hormonal effects.
