Resumen
Native perennial legume Adesmia bicolor reveals characteristics that are key to securing persistence under grazing. Literature on the diversity and symbiotic effectiveness of indigenous rhizobia-nodulating A. bicolor in central Argentina is limited. The purpose of this study was therefore to determine phenotypic and genotypic variability as well as biological N-fixation effectiveness in rhizobia isolated from A. bicolor nodules. To this end, repetitive genomic regions were analyzed using ERIC primers. In the greenhouse, plants were grown under a (i) N-fertilized treatment, (ii) N-free control treatment, and (iii) rhizobia inoculation treatment. Dry weight and N-content were analyzed. All isolates belonged to Rhizobium genus and showed high symbiotic effectiveness. The N-content/subterranean N-content ratio in aerial and subterranean parts of inoculated plants was higher than that observed in N-fertilized plants during the vegetative stage. Results from this study demonstrate that symbiosis between native rhizobial strains and A. bicolor is very effective. © 2012 Springer Science+Business Media New York.
