Effects of Latitude and Weather Conditions on Proanthocyanidins in Blackcurrant (Ribes nigrum) of Finnish Commercial Cultivars

Blackcurrants of three Finnish commercial cultivars ‘Mortti’, ‘Ola’ and ‘Melalahti’ cultivated in southern and northern Finland were compared on the basis of the content and composition of proanthocyanidins (PAs). Seventeen B-type PA oligomers (degree of polymerization 2-5 and 7) were detected by hy...

Description
Summary:Blackcurrants of three Finnish commercial cultivars ‘Mortti’, ‘Ola’ and ‘Melalahti’ cultivated in southern and northern Finland were compared on the basis of the content and composition of proanthocyanidins (PAs). Seventeen B-type PA oligomers (degree of polymerization 2-5 and 7) were detected by hydrophilic interaction liquid chromatography and electrospray ionization mass spectrometry. Total PAs, dimers, trimers and tetramers were quantified. Among the three cultivars, ‘Ola’ had the highest contents of both total PAs and PA oligomers. ‘Melalahti’ was separated from both ‘Mortti’ and ‘Ola’ by PA profiles in the partial least squares discriminant analysis model. All three cultivars revealed distinct responses to latitude and weather conditions. The content of total PAs showed a positive correlation to latitude in ‘Ola’ and ‘Melalahti’. Among the meteorological variables, high temperature and radiation correlated negatively with total PAs, while only specific variables showed a correlation with PA oligomers.
