FIGURE 4.

Phenotypic effect of P. polymyxa LMG27872 on tomato seedlings. Treatment of 3-day-old seedlings with 1 mL of bacterial inoculum at different bacterial suspension doses of 30, 50, and 100% was performed, while control plants were mock- and buffer-treated. The (A) SH, (B) SW, (C) RL, and (D) RW measured at 5 days after application. (E) Shoot and root growth of 5-day-old seedlings treated with 30, 50, and 100% BS. Data analyzed by one-way ANOVA, followed by Tukey’s post-hoc test, and data are shown by box plots with median, upper, and lower quartiles. Different letters indicate statistically different means at 95% confidence.
