Abstract
This dataset includes metabolic data and different functional traits of two different pine species including trees in decline and healthy trees. One dataset includes all different shared metabolites identified in the two species and individuals sampled under peak drought stress. The second dataset includes functional traits from gas exchange, hydraulics and osmotic relationships. These functional traits were assessed during two study years with contrasting summer drought.
