Flavonols were similarly induced by UVA and UVB radiation in Arbutus unedo leaves.
- class="label">•
UVB was more efficient than UVA in inducing flavonol synthesis in Vitis vinifera.
- class="label">•
From no UV to radiation with the whole solar spectrum flavonols increased more in Vitis vinifera than in Arbutus unedo.
- class="label">•
In Vitis vinifera the I-P phase was higher in leaves developed in fully solar radiation.

UV induces damage of the oxygen evolving complex in Vitis vinifera but not in Arbutus unedo.
