Table 4. Effect of the exposure to Ceratocystis fimbriata on the morphology of Monilinia fructicola and Penicillium digitatum observed by SEM.
| Test pathogens | CK x | F (5 DPI) y | R (5 DPI) z | |
|---|---|---|---|---|
| M. fructicola | Hyphal diameter (μm) | 4.57 ± 0.19 a | 3.43±0.20 b | 3.46±0.20 b |
| Branch number (/100 mycelia) | 0 b | 98 a | 100 a | |
| Conidia size (μm) | (11.57±0.63) × (5.30±0.32) b | (15.85±0.31) × (8.49±0.25) a | (15.67±0.26) × (8.46±0.18) a | |
| P. digitatum | Hyphal diameter (μm) | 4.68±0.17 a | 2.52±0.31 b | 2.55±0.27 b |
| Branch number (/100 mycelia) | 0 b | 97 a | 99 a | |
| Conidia size (μm) | (4.54±0.29) × (3.29±0.18) a | (4.33±0.28) × (2.45±0.26) a | (4.35±0.17) × (2.49±0.25) a | |
Hyphal diameter (μm) and conidia size (μm) were expressed as mean value ± SD.
x CK = Growing normally.
y F = Treated, 5-day exposure to C. fimbriata volatile compounds.
z R = Recovered, transferred to a fresh PDA plate after 5-day exposure to C. fimbriata volatiles.
a and b represent statistically significant differences between the control, treated and recovered treatment (p < 0.05).
