The in vitro plant-growth-promoting potential of three Pseudomonas strains.
| Bacterial strains | |||
|---|---|---|---|
| P. koreensis HCH2-3 | P. lurida FGD5-2 | P. rhodesiae MTD4-1 | |
| Inorganic phosphate solubilization (SI) | 2.15 ± 0.11b | 3.97 ± 0.15a | − |
| Siderophore production (SPI) | 2.61 ± 0.13a | 1.89 ± 0.07b | 2.18 ± 0.08b |
| Protease activity (PAI) | 1.52 ± 0.07b | 1.93 ± 0.09a | 1.98 ± 0.07a |
| IAA production (μg/mL) | 28.12 ± 1.09a | 12.76 ± 1.48c | 16.60 ± 0.25b |
| Catalase activity | + | + | + |
| Ammonia production | + | + | + |
Values were analyzed and expressed as mean ± standard error (n=3) based on duplicate experiments, and data sharing the different letters were significantly different (p<0.05). The plus (+) means apparent activity/production; the minus (−) means no activity/production.
