Mudas de Eucalyptus grandis e E.urophylla foram inoculadas na epoca da semeadura com o fungo Pisolithus tinctorius. As mudas foram produzidas em tubetes contendo uma mistura de vermiculita e turfa, e receberam as praticas culturais de um viveiro comercial. O inoculo constou de micelio do fundo crescendo sobre vermiculita/turfa umedecida com meio MMN. Nao foi observada a formacao de ectomicorrizas tipicas e, embora com tendencia a maior crescimento, as mudas inoculadas nao apresentaram desenvolvimento significativamente superior ate os 170 dias de idade. Em outro ensaio, mudas de E.grandis com 45 e 75 dias foram inoculadas com uma suspensao de fragmentos de micelio. As mudas inoculadas aos 45 dias mostraram maior percentagem de raizes com manto fungico e tendencia a um maior desenvolvimento aos 130 dias de idade. As mudas inoculadas aos 75 dias nao mostraram efeito da inoculacao, quando avaliadas aos 160 dias de idade. |

Plant growth-promoting bacteria (PGPB) are bacteria that have mechanisms that facilitate plant growth in stress conditions such as drought. The objective of this study was to characterize bacterial strains isolated from bromeliads roots in ironstone outcrops (Urucum Residual Plateau, Mato Grosso do Sul, Brazil) for plant growth-promoting under drought conditions. Firstly, we screened isolates with the presence of 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity. Then, all isolates were tested for tolerance to drought, exopolysaccharides (EPS) production, indole-3-acetic acid (IAA)-producing abilities, phosphate and zinc solubilization, production of catalase and hydrolytic enzymes (amylase, cellulase, and protease). Germination assay and a pot experiment with maize plants submitted to well-watered and drought conditions were performed with the strains most promising (VBN11 and VBE23). Briefy, Bacillus cereus VBE23 showed in vitro higher ACC deaminase activity (3.83 and 2.52µmol α-KB mg−1 h−1 in non-drought and drought conditions, respectively), tolerance to drought, EPS production and other mechanisms of plant growth promotion: solubilization of phosphate and zinc, ammonia production, catalase activity and production of hydrolytic enzymes (amylase, cellulase, and protease). Inoculation of strain VBE23 in maize seeds submitted to drought conditions showed higher germination concerning uninoculated seeds and inoculated with VBN11. Also, the results indicated that the isolate VBE23 provided higher values of fresh and dry biomass compared to the control of uninoculated treatment and inoculated with VBN11 under drought conditions. This is the frst report on the PGPB from ironstone outcrops of Urucum Residual Plateau, Mato Grosso do Sul, Brazil. Thus, this bacterial isolate could be used as a strategy for the facilitation of plant growth in drought environments MenosPlant growth-promoting bacteria (PGPB) are bacteria that have mechanisms that facilitate plant growth in stress conditions such as drought.
