Agro-morphological and biochemical characteristics of european cranberrybush (Viburnum opulus L.)

The study aims to determine some agro-morphological (fruit weight, fruit flesh ratio, fruit skin colour, number of fruits per raceme, number of racemes per bush), and biochemicals (vitamin C, soluble solid content, organic acids, total phenol, total anthocyanin, total flavonoid and antioxidant capacity) in fruits of ten promising European cranberrybush (Viburnum opulus L.) genotypes grown in Erzurum province in Turkey. The results showed genotype-specific differences in most of the agro-morphological, biochemical and bioactive characteristics. The genotypes had fruit weight, number of fruits per raceme and number of racemes per bush between 0.58 and 0.80 g; 38.4 and 58.2 and 392 and 543, respectively. The vitamin C and soluble solid content were ranged from 33 to 42 mg per 100 g and 11.3 to 13.1%. Total phenol, total anthocyanin and total flavonoid content ranged from 703 to 911 mg gallic acid equivalent per 100 g fresh weight, 22–48 mg per 100 g expressed cyanidin-3-rutinoside, 187–302 mg routine equivalent per 100 g fresh weight. Genotype ERZ-08 had the highest antioxidant capacity as 32.70 µmol trolox equivalents per gramme based on FRAP assays. © 2018, Academic Publishing House. All rights reserved.
