Sample note
The black coloured fruits from one genotype from the location Palanka, North Serbia were collected by the researchers. Each genotype as represented by one tree, and each sample was taken from one individual plant. The tree was over 30 years old and originated from seed. All berries were picked at the biologically ripe stage. The berries were picked cardinally-oriented branches with different directions arond the canopy. Harvest time was between 10 and 20th June 2011. After picking, the fruits were stored at -20C until chemical analysis.
