Values are indicates common error of two independent experiments with three replicates ( = 6). Unique letters in a column indicate significant variations among suggests as determined by the DGC test ( = 0.05).A. salinestris AT37 and a. chroccoccum AT25 strains presented intermediate levels (6.5 mmol C2 H4 mg protein1 24 h1 ), and also the lowest values (3 mmol C2 H4 mg protein1 24 h1 ) were discovered within a. salinestris AT18 and AT19 strains (Figure 3(d)). A. salinestris AT19 made the highest degree of IAA (18.two g mL1 ), the lowest amount of GA3 (0.3 g mL1 ), and an intermediate worth of Z (0.8 g mL1 ). By contrast, A. salinestris AT18 and AT37 showed the lowest levels of IAA production (two.two.6 g mL1 ) and also the highest levels of GA3 production (0.7 g mL1 ). These two strains, however, differed in their Z synthesis: though AT18 was one of several largest Z producers (1.two g mL1 ), AT37 exhibited the lowest production (0.five g mL1 ). Similar tendencies wereobserved when strains AT42 and AT31 were compared. Striking outcomes were obtained with a. chroccoccum strain AT25, whose production of the three phytohormones was always in intermediate levels (Figures 3(a), 3(b), and.
