Abstract
Inoculation of Phaseolus vulgaris with Azospirillum brasilense Cd prom oted root hair formation in seedling roots and significantly increased total and upper nodule numbers at different concentrations of Rhizobi um inoculum. In experiments carried out in a hydroponic system, A. bra silense caused an increase in the secretion of nod gene-inducing flavo noids, as was observed by nod gene induction assays of root exudates f ractionated by high-performance liquid chromatography. Possible mechan isms involved in the influence of A. brasilense on this symbiotic syst em are discussed.
