| Popis: | Soil pollution by heavy metals occurs mainly due to poor management of wastes generated by mining during the exploitation and processing of metals, regarding to soil environment concern, this research aimed to: Evaluate the tolerance and the effectiveness of native rhizobium strains in soils of Mn mining areas in association with leguminous species grown under increasing concentrations of Mn. Initially, isolates of soil native rhizobia from the Mn mining area were obtained, with cowpea and sabiá as trap plants. Subsequently these isolates were authenticated and morphologically characterized. Two experiments were carried out using a natural soil to observe the effect of Mn on the leguminous species growth and nodulation, the evaluated variables were: number of nodules (NN); nodules dry mass (NDM); shoot dry matter mass (SDMM); shoot nitrogen content; manganese content in the aerial part of the plants and nitrogen accumulation in the aerial part (NAAP). Data were submitted to variance analysis. Qualitative variables were compared by the Scott-Knott test (p |
