N2-fixing bacteria in the rhizosphere: quantification and hormonal effects on root development



N2-fixing bacteria in the rhizosphere: quantification and hormonal effects on root development



Zeitschrift fur Pflanzenernahrung und Bodenkunde 152(3): 237-245



Experimental results on enumeration of N2-fixing bacteria (diazotrophs) and hormonal effects of Azospirillum on root development are reviewed. Numbers of N2-fixing and N-heterotrophic bacteria were determined on the root (rhizoplane plus 'inner' root surface) and in the rhizosphere soil (0-3 mm from the root surface) of Arrhenatherum elatius, other forage grasses and some herbaceous plants.
