Light: An Alternative Method for Physical Control of Postharvest Rotting Caused by Fungi of Citrus Fruit

Table 2

Effects of UV-B irradiation on the postharvest rotting caused by P. italicum and P. digitatum.

Citrus species	Fungi species	Treatment/intensity	Mechanism of action	References
Lemon	P. digitatum	UV-B (22,000 J·m^−2·d^−1) lamps placed 50 cm above the fruit	Increase in cell wall thickness and concentration of phenolics in the flavedo	[67]
Lemon	P. digitatum	UV-B (22,000 J·m^−2·d^−1) lamps placed 50 cm above the fruit	Increase in ROS and membrane permeability, which results in improved antifungal activity	[44]
Mandarin	P. italicum	In in vitro studies, fruits were placed 15 cm below UV-B lamps at 15, 30, 60, and 120 kJ·m^2	Inhibit the germination of fungi spores by directly inactivating fungi and inducing an antifungal response in fruits	[68]
