Fig. 4. Effect of different concentrations of Paenibacillus polymyxa strain SG-6 on control of green mold decay (Penicillium digitatum) incidence (a) and lesion diam- eter (b) in wounded citrus fruit after storage at 25 ◦ C and 95% RH for 5 d. (A)1 × 106 cells mL−1 washed cell suspension of strain SG-6; (B) 1 × 107 cells mL−1 washed cell suspension of strain SG-6; (C) 1 × 108 cells mL−1 washed cell suspen- sion of strain SG-6; (D) 1 × 109 cells mL−1 washed cell suspension of strain SG-6;and (control) sterile distilled water. Each value is the mean of three replicates via two experiments. Bars represent the standard deviations of the mean. Statistical significance was determined at P < 0.05 according to the Tukey’s HSD test.
