Method 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 b-carotene on a chlorophyll content basis.
Comments This is total chlorophyll concentration on a leaf area basis (Chl(a+b)), average of sun and shade in a study area (ARR) in Portugal.
