The aim is to evaluate how plant growth-promoting rhizobacteria affect soybean growth and physiology at suboptimal root zone temperatures.
Nine PGPR strains were tested in soybean rooting media.
Three root zone temperatures (25, 17.5, and 15 °C) were applied.
Performance of PGPR on plant growth and physiological status was assessed at each temperature.
At 15 °C, Serratia proteamaculans 1–102 significantly improved growth.
At 17.5 °C, Aeromonas hydrophila P73 enhanced plant development.
At 25 °C, Serratia liquefaciens 2–68 showed stimulatory effects on growth.
