| isolation and characterization of ni mobilizing pgpb from serpentine soils and their potential in promoting plant growth and ni accumulation by brassica spp. | the study was undertaken to assess the effects of ni mobilizing bacteria on the plant growth and the uptake of ni by brassica juncea and brassica oxyrrhina. among a collection of ni resistant bacterial strains isolated from the non-rhizosphere and rhizosphere soils of alyssum serpyllifolium and astragalus incanus at a serpentine site in bragança, north-east of portugal, nine strains were selected based on their ability to solubilize ni in soil. further assessment on plant growth-promoting parame ... | 2009 | 19232424 |
