Resumo: The evaluation of native rhizobia strains potential as related to efficiency, competitiveness, and adaptation in regions subjected to high temperature is important to the study of nitrogen symbiotic fixation. The objective of this research was the morphologic characterization of rhizobia isolated from samples of a red yellow argisol of Serra Talhada municipality, Pernambuco State, Brazil, and selection for high temperature and kanamicina and nalidixic acid antibiotics resistance. The study was carried out at Institute of Agricultural Research of Pernambuco (IPA). The isolates were cultivated in YMA media to evaluate colonie characteristics as acidity or alkalinity production, growing velocity, color, shape and transparency, elevation, and mucus production. All isolates were compared to the standard strain Bradyrhizobium sp. 6145, recommended for cowpea. The morphological and physiological diversity of the isolates enabled the identification of distinct groups. The isolates 1, 2 and 4 presented higher resistance to high temperature and adaptation to survive in regions subjected to thermal stress periods. The isolate 1 showed the highest resistance to tested antibiotics. KEY-WORDS: Rhizobia; morphologic characteristics; high temperature.

A avaliação do potencial de estirpes nativas de rizóbio em relação à eficiência, competitividade e adaptação às regiões sujeitas à alta temperatura é importante no estudo da fixação simbiótica de nitrogênio. O objetivo do trabalho foi efetuar a caracterização morfológica de isolados de rizóbios a partir de amostras de um argissolo vermelho amarelo do Município de Serra Talhada (PE), e selecioná-los quanto a resistente a alta temperatura e aos antibióticos kanamicina e ácido nalidíxico. O estudo foi conduzido na Empresa Pernambucana de Pesquisa Agropecuária (IPA) Os isolados foram crescidos em meio YMA e obsevado: formação de álcali e ácido, tempo de crescimento, cor, transparência, elevação, forma e produção de muco. Todos os isolados foram comparados à estirpe padrão Bradyrhizobium sp. 6145, recomendada para o caupi. A diversidade morfológica e fisiológica dos isolados permitiu a obtenção de diferentes grupos. Os isolados 1, 2 e 4 apresentaram maior resistência à temperatura elevada mostrando-se mais adaptados a sobreviver em regiões sujeitas a períodos de estresse térmico. O isolado 1 obteve maior resistência aos antibióticos testados.
