Resumo: O objetivo deste trabalho foi avaliar os efeitos da inoculação do feijoeiro com bactérias promotoras de crescimento de plantas. Os microrganismos foram isolados de solo próximo às raízes de feijão, em quatro tipos de solo. Um total d e 360 bactérias foi selecionado quanto à capacidade para produzir fitohormônios e de solubilizar fosfato. As bactérias selecionadas foram testadas no feijoeiro em casa de vegetação. O delineamento experimental foi inteiramente casualizado, em esquema fatorial (2 x 8), com três repetições e os tratamentos: feijão não inoculado e inoculado com as bactérias K24, K36, K71, T30, T79, A24 e T22, isoladamente. Em todos os tratamentos o feijoeiro foi cultivado na presença e ausência de fertilização fosfatada. As bactérias K36... |

Studies with streptomycetes in biocontrol programs and plant growth promotion are presented as technological alternatives for environmental sustainable production. This work has the objective of characterizing six isolates of streptomycetes aiming the production of extracellular enzymes, indole acetic acid, capacity for phosphate solubilization, root colonization and growth under different pH and salinity levels. For detection of enzyme activity the isolates were grown in culture media with the enzyme substrates as sole carbon source. The root colonization assay was performed on tomato seedlings grown on 0.6% water-agar medium. Growth under different pH and salinity levels was evaluated in AGS medium with 1%, 1.5%, 2%, 2.5%, and 3% NaCl, and pH levels... |

Melatonin is an environmentally friendly-molecule with a potent free radical scavenger and antioxidant capacity. Two pot experiments were conducted during two successive winter seasons (2011/2012 and 2012/2013) at the wire-house of the National Research Centre, Dokki, Cairo, Egypt to study the potentiality of melatonin (100 mM and 500 mM) in alleviating the harmful effect of diluted seawater at a relatively low and high concentrations (3.85 dS/m and 7.69 dS/m, respectively) on the performance of faba bean plants. The results revealed that irrigation of faba bean plants with diluted seawater reduced growth parameters (plant height, leaves number/plant, fresh and dry weights of plant), relative water content (RWC), photosynthetic pigments (chlorophylls a, b... |
