Effect of Bacillus velezensis CLA178 on biomass of rose under crown gall disease stress. (A) Representative image of rose inoculated with the strains for 30 days. The leaf area (B), root fresh weight (C), photosynthetic rate (D), and chlorophyll content (E) of rose were determined. The rose plants were infected with C58 one day after inoculation with CLA178. The untreated and CLA178-pretreated rose plants treated with PBS (control) or infected with the C58 pathogen infection are shown. The values are the mean ± SD. Different letters above the bars indicate significant differences between the treatments (Duncan’s least significant difference, P < 0.05, n = 6).
