Values are suggests typical error of two independent experiments with 3 replicates ( = 6). Unique letters inside a column indicate important differences involving implies as determined by the DGC test ( = 0.05).A. salinestris AT37 and also a. chroccoccum AT25 strains presented intermediate levels (six.5 mmol C2 H4 mg protein1 24 h1 ), along with the lowest values (three mmol C2 H4 mg protein1 24 h1 ) had been identified within a. salinestris AT18 and AT19 strains (Figure three(d)). A. salinestris AT19 produced the highest degree of IAA (18.two g mL1 ), the lowest degree of GA3 (0.three g mL1 ), and an intermediate worth of Z (0.eight g mL1 ). By contrast, A. salinestris AT18 and AT37 showed the lowest levels of IAA production (2.two.six g mL1 ) and also the highest levels of GA3 production (0.7 g mL1 ). These two strains, having said that, differed in their Z synthesis: whilst AT18 was on the list of largest Z producers (1.2 g mL1 ), AT37 exhibited the lowest production (0.5 g mL1 ). Related tendencies wereobserved when strains AT42 and AT31 were compared. Striking results have been obtained using a. chroccoccum strain AT25, whose production from the 3 phytohormones was generally in intermediate levels (Figures 3(a), 3(b), and.
