NMR metabolomics of sea buckthorn berries of the cultivars ‘Terhi’ and ‘Tytti’.
Phenotypic plasticity is revealed when comparing different growth sites.
Sub-arctic latitude has a major phenological effect on berry composition.
Ethyl glucoside is accumulated during ripening in southern growth conditions.
Key fingerprints were quinic acid for ‘Terhi’ and ethyl glucoside for ‘Tytti’.
