Effects of Latitude-Related Factors and Geographical Origin on Anthocyanidin Concentrations in Fruits of Vaccinium myrtillus L. (Bilberries)

摘要

Two data sets are presented to identify the effect of growth location and origin of parental plant on anthocyanidin concentrations in Vaccinium myrtillus fruits. Bilberries were Collected from wild populations growing at different latitudes and from cultivated plants originating from different geographical locations but grown in the same location for over 10 years. High-performance liquid chromatography analysis showed that anthocyanidin concentrations varied significantly with latitude and with geographical origin, with higher values form northern latitudes or from a more northerly origin of parent plants. The results show that anthocyanidin concentrations in bilberries are under strong genetic control but are also influenced by climatic factors. Furthermore, the proportions of specific anthocyanidins differed between latitudes and between plants with different parental origins. The diversity in anthocyanidin concentration and composition has important implications for plant breeders and for future development of varieties with high antioxidant capacity.
