Studies on associative nitrogen fixation by antibiotic-resistant mutants of Azospirillum brasilense with genotypes of lentil (Lens culinaris) Rhizobium strains in calcareous soil
Published online by Cambridge University Press: 27 March 2009
Summary
Nitrosoguanidine-induced mutation frequencies for resistance to streptomycin, spectinomycin, erythromycin and novomycin were studied in Azospirillum brasilense. Lentil inoculated with A. brasilense and its mutants and Rhizobium strains produced increased nodule dry weight, nitrogenase activity of nodules and roots and grain yield compared with an uninoculated control.
