Fig 2. A, B, C and D. An increase in plant growth with sustained Bacillus amyloliqefaciens FZB42 exposure compared with FZB42 withdrawn at 64 day and water-treated controls as determined by fresh weight and dry weight.

Fresh weight [A], and dry weight [B] for 65-days plants continuous exposed to FZB42 volatiles (n≥10) or water controls (n ≥10). Fresh weight [C], and dry weight [D] for 71-days old plants continuous exposed to FZB42 volatiles (n ≥10), FZB42 withdrawn at 65 day (n ≥10) and water controls (n ≥10). Different letters indicate significant differences between treatments (ANOVA, p ≤ 0.05).
