Conteúdo: | Rhizobial strain-soybean genotype interactions for symbiotic nitrogen fixation activity were analysed for the pairs associating 5 host genotypes and 3 (2 slow-and 1 fast-growing) rhizobial strains on plants grown hydroponically. Genetic variations were observed for strains and cultivars but the interactions between micro- and macro- symbiots prevailed in the expression of the symbiotic nitrogen fixation rates. A selection of the rhizobial strain-soybean genotype combinations that optimiza N2 fixation can be considered at a relatively early stage (R2) of plant growth. Chlorophyll fluorescence and dry matter production at definite growth stages (R2 or R5) are simple, reliable and rapid criteria.
