Effect of Ultraviolet-B Irradiation on Disease Development Caused by <i>Penicillium italicum</i> in Satsuma Mandarin Fruit

Abstract: Blue mold (Penicillium italicum) is the primary postharvest pathogen affecting citrus fruit. In the present study, we investigated the effect of ultraviolet (UV-B) irradiation on blue mold, and the influence of UV-B on the internal fruit quality and peel color of satsuma mandarin. All UV-B doses examined (15, 30, 60, and 120 kJ·m −2 ) had inhibitory effects on P. italicum growth in vitro (reduction of spore germination > 99%). Additionally, we examined the disease incidence, the soft rot (water soaked) area di… Show more

“…Successful results for UV-B were also noted for mandarins. In one of these studies by Yamaga et al [68], it was note that the UV-B (15, 30, 60, and 120 kJ•m −2 ) treatment significantly reduces the germination of P. italicum spores on the "satsuma" mandarins.…”

“…UV-B presents less harmful effects compared to UV-C, which reduces the incidence of blue mold. The mechanisms of action of UV irradiation are divided between direct, due to the absorption of radiation by the surface of the fungus that inactivates its conidia, and indirect, by the induction of metabolic and anatomical alterations in the citrus flavedo, increasing the resistance of the fruit against the pathogen, making their cell walls thicker (Yamaga et al, 2016;Ruiz et al, 2017;Papoutsis et al, 2019). In addition, after treatment, there is an accumulation of polyphenols and phytoalexins in the flavedo, which are secondary metabolites with antifungal activities.…”

“…Numerous studies have highlighted that the development of nonionizing and ionizing radiation could reduce the incidence of fungal infections in fruits (Gündüz & Pazir, 2013; Jeong et al., 2016; Liao et al., 2013; Yamaga et al., 2016). The effectiveness of fruit rot reduction depends on the type of irradiation, as well as its penetration capacity (Jeong et al., 2016; Rojas‐Argudo et al., 2012).…”
