- •
Arbutus unedo plants grew under different UV/precipitation treatments in the field.
- •
Leaf phenolic content and antioxidant activity were mainly affected by season.
- •
Theogallin and quercitrin increased upon leaf exposure to UV-A and UV-B respectively.
- •
UV-A exposure under reduced rainfall decreased leaf quercetins and one kaempferol.
- •
Leaf antioxidant activity increased by UV-A and UV-B under low watering.
