Resumo: Biological nitrogen fixation is of fundamental importance for agricultural sustainability, and the evaluation of the rhizobial diversity contributes to the knowledge of their diversity in collections, as well as for later use in agricultural systems. The objective of this paper was to evaluate phenotype diversity and symbiotic efficiency of rhizobia isolates from Amazonian soils when inoculated on cowpea (Vigna unguiculata L. Walp.). The native isolates presented diversity regarding their morphologic and physiological characteristics. It was verified that the inoculation with isolates of native rhizobia contributed to the increase of the biomass, nodulation on cowpea and symbiotic efficiency.

O objetivo deste trabalho foi avaliar a diversidade fenotípica de rizóbio isolados de solos da Amazônia e suas eficiências simbióticas quando inoculados em feijão caupi (Vigna unguiculata L. Walp.). Os isolados nativos apresentaram diversidade quanto às características morfológicas e fisiológicas. Foi verificado que a inoculação com isolados de rizóbio nativos contribuiu, de forma significativa, para o aumento da biomassa, nodulação de caupi e em eficiência simbiótica.Universidade Estadual de Maringá2009-11-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/90010.4025/actasciagron.v32i1.900Acta Scientiarum.
