||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.
||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.
