N2 - Azospirillum brasilense Cd was grown with either malate or fructose as the carbon source. Malate-grown cells formed aggregates, whereas those grown with fructose remained separate. Scanning electron microscopy revealed a larger number of fructose-grown cells adsorbed to the root surface of inoculated maize (Zea mays) plants, as compared to the number of malate-grown cells adsorbed under similar conditions. Inoculation with fructose-grown bacteria resulted in a higher significant increase in root surface area and root and foliage dry weight of maize seedlings, as compared to plants inoculated with malate-grown bacteria or the controls. Inoculation of oak (Quercus ithaburansis Decaisne) seedlings with fructose-grown bacteria, did not significantly promote any of the above characteristics, whereas malate-grown cells at 107 cfu plant-1 significantly improved the development of oak seedlings in the first month after sprouting.
