Symbiotic performance of TER strains with P. vulgaris. Bean plants were inoculated with the different strains, after 21 dpi symbiotic performance was analyzed by: (A) nitrogenase-specific activity by ARA, (B) leghemoglobin content, (C) number of nodules per plant, (D) shoot dry weight, and (E) root dry weight. Strains: CFNX182-1 (black bars), TER31 (gray bars), TER38 (white bars), and TER49 (striped bars). A t-test (P < 0.05), was used to determine statistically significant differences in the nitrogenase specific activity in (A). 0.0021 (**), 0.0001 (****).
