Dose-dependent inhibition of B. cinerea mycelial growth, spore germination, and spore development by B. subtilis GB03 volatile compounds. (A) Spore germination, (B) spore formation, and (C) mycelial growth of B. cinerea were measured after 7 days in the presence of one, two, or three spot-inoculated filter disks (5 mm diameter) of B. subtilis GB03 bacterial suspension (10⁸ CFU/ml) that were allowed to grow for 24 h before addition of fungi. Different letters indicate significant differences between treatments according to Fisher’s LSD test at P = 0.05. Error bars indicate standard error of the mean (SEM).
