Characteristics of bacterial isolates. a Quantification of ACC (1-aminocyclopropane-1-carboxylate) deaminase production. b Indole acetic acid (IAA) content observed in culture broth (CB) of SAK1. SAK1 was grown in culture broth (CB) with high NaCl concentrations (100, 200, 300, and 400 mM). c Content of abscisic acid (ABA) in CB of SAK1. SAK1 was grown in CB with high NaCl concentrations (100, 200, 300, and 400 mM). Each data point is the mean of three replicates. Error bars represent standard errors. The bars represented with different letters are significantly different from each other as evaluated by DMRT analysis
