| Bactérias produtoras de ácido indolacético, em condições ideais de substrato, podem induzir o crescimento de mudas micropropagadas de abacaxizeiro e se tornar uma alternativa de redução dos protocolos de aclimatação ou mesmo facilitar a adaptação das plantas ao campo. No presente trabalho, verificou-se o crescimento de mudas micropropagadas de abacaxizeiro 'BRS Imperial', em fase de aclimatização, utilizando como substratos: 1) Turfa; 2) Fibra de Coco; 3) Vivatto ® ; 4) Fibra de Coco + Vivatto ® ; 5) Fibra de Coco + Vermiculita; 6) Fibra de Coco + Turfa. Todos suplementados, a cada 15 dias, com suspensões de rizobactérias da coleção de trabalho do Laboratório de Microbiologia do Solo e Resíduos Orgânicos da Embrapa Mandioca e Fruticultura. Avaliaram-se a... |

| ABSTRACT In the banana production system, a sustainable alternative for producing quality plantlets would be inoculation with plant growth-promoting bacteria (PGPB). Therefore, this study aimed to evaluate the growth-promoting potential of a bacterial biomass in micropropagated banana plantlets cultivar Prata Catarina, and to identify the mechanisms involved in plant-microorganism interactions. In vitro, the biochemical assays tested were the solubilisation of phosphates, production of enzymes, production of ammonia, siderophores, and indole acetic acid. In the in vivo tests, the plants were bacterised (109CFU mL-1) in two phases: acclimatisation, and cultivation in plastic bags. The design was a randomised block with 9 and 7 repetitions per treatment,... |

| ABSTRACT This study aimed to explore the effects of two siderophore-producing bacterial strains on iron absorption and plant growth of peanut in calcareous soil. Two siderophore-producing bacterial strains, namely, YZ29 and DZ13, isolated from the rhizosphere soil of peanut, were identified as Paenibacillus illinoisensis and Bacillus sp., respectively. In potted experiments, YZ29 and DZ13 enhanced root activity, chlorophyll and active iron content in leaves, total nitrogen, phosphorus and potassium accumulation of plants and increased the quality of peanut kernels and plant biomass over control. In the field trial, the inoculated treatments performed better than the controls, and the pod yields of the three treatments inoculated with YZ29, DZ13, and YZ29 +... |
