P-solubilizing performance and plant-growth-promoting ability of strain PSB-2. (A) Halo zones of strain PSB-2 in solid NBRIP media containing different amounts of tricalcium phosphate (i.e., A1, A2, A3, A4, A5, and A6). (B) Ratios of halo diameter (HD) to colony diameter (CD) of strain PSB-2 in solid NBRIP media containing different amounts of tricalcium phosphate. Lowercase letters above the column denote significance (P < 0.05). (C) Plant-growth-promoting performance of strain PSB-2. (D) Differences in vegetation properties (i.e., plant fresh weight, plant dry weight, plant height, shoot P, and root P) between the no PSB-2 addition group (CK) and the PSB-2 addition group (Exp). Units for parameters: g (fresh weight and dry weight), cm (plant height), mg/g dry weight (shoot P and root P). Asterisks denote significance (***, P < 0.001).
