||Chlorophylls and carotenoids were separated by HPLC (Waters Corp., Milford, MA, USA), following pigment extraction in cool acetone. The peaks were identified and quantified with pure commercial standards (VKI, Hørsholm, Denmark). Three light-responsive pigment pools were determined: total chlorophyll on a leaf area basis, and xanthophyll cycle pigments (VAZ) and ß-carotene on a chlorophyll content basis.
||Average of sun and shade values in 9 study areas in Spain and Portugal.
