Evolution of postharvest necrotrophic fungi (including gray mold) incidence on representative strawberry (Fragaria × ananassa ‘Camarosa’) fruits belonging to the different treatments performed in the present research. Each group of fruits subjected to different methyl jasmonate (MeJA) treatments during fruit development (C, M1, M2, and M3) were inoculated by injecting 20 μL of the Botrytis cinerea conidia suspension (+Bc) or distilled water (−Bc) with a sterile syringe. Fruits were maintained in humidity chamber at 20 °C up to 72 h post-inoculation (hpi). Gray mold incidence in +Bc and −Bc fruits was recorded at 24, 48 and 72 hpi.
