Growth promotion of pepper rhizomes by four strains of Bacillus and their complex solutions. The experiments were conducted three times, each with three replicates. One asterisk (*) indicates a significant difference (p< 0.05) between strain FZB42 and compound formulation treatment, and two asterisks (**) indicate a highly significant difference (p< 0.01) between strain FZB42 treatment and strain HAB-2 treatment by the one-way ANOVA. (A) Determination of root length. (B) Determination of stem diameter.
