dc.descriptionAiming to evaluate the effects of isolated and joint inoculation of rhizobacteria in corn hybrids under different water regimes, strains of Azospirillum brasilense and Bacillus sp. were inoculated in seeds of two maize hybrids with contrasting drought characteristics and exposed to Field Capacity and Water Deficit. During pre-flowering, the plants were kept under water deficit for 14 days. After this period, the root system morphology, relative leaf chlorophyll content, maximum quantum efficiency of photosystem II (PSII), and production parameters were analyzed. Regarding root morphological characteristics, the hybrids showed opposite responses: DKB390 increased all evaluated factors when inoculated with Azospirillum, whereas P30F53 did not. The inoculants promoted beneficial effects in maize genotypes under water-deficit conditions, resulting in increased grain production. Coinoculation promoted higher averages across all evaluated parameters for the drought-sensitive hybrid. In irrigated plants, the inoculant Azospirillum conferred higher chlorophyll content in both maize genotypes. Photosystem II inhibition was observed in plants exposed to water deficit after 7 days of stress; however, the inoculant Azospirillum showed higher values for both hybrids. Thus, these results suggest that the plant-bacteria interaction is linked to genetic material, as corn hybrids with divergent drought behaviors exhibit different responses to plant growth-promoting rhizobacteria (PGPR) inoculation.
