Plant-growth-promoting bacteria of the genus Azospirillum and Herbaspirillum can improve crop yields of maize in tropical environments. The main mechanism proposed for its promotion is related to the auxins produced by these species. The aim of this study was to compare the maize growth response of inoculation using two species, Azospirillum baldaniorum Sp245 (Ab-Sp245) and Herbaspirillum seropedicae ZAE94 (Hs-ZAE94) during the initial growth under controlled conditions. A pot experiment was conducted with five harvests measuring bacterial counts, root morphology, biomass, and nitrogen content, and soluble metabolites for 38 days. Depending on the harvest period, a differential growth response between the two strains test was compared to the control. Plants use the bacterium applied to improve nitrogen acquisition and transform it into higher biomass and nitrogen accumulation, especially for Ab-Sp245. On the other side, Hs-ZAE94 altered the soluble metabolites resulting in higher NO3 - , NH4 + , and N-amino and lower soluble fractions compared to Ab-Sp245 and the control. The observed plant-bacteria interaction is closely fine-tuned and regulated by the strain used and differences in growth promotion effects cannot solely attributed to the root morphology. |
