Fruit quality attributes of blackberry grown under limited environmental conditions
Article (Published version)
MetadataShow full item record
Fruit quality attributes were studied for two consecutive years in seven blackberry cultivars grown in a Serbian climate and on acidic soil. Physical parameters [berry weight (BW), size and shape] and chemical parameters [soluble solids content (SSC), acidity, total phenolic (TPH) and flavonoid content (TFC) and total antioxidant capacity (TAC)] were evaluated. A high variability was found in the set of the evaluated blackberry cultivars and significant differences were found among them in all studied quality attributes. Year-by-year variations were observed for all quality traits, except berry length (L) and berry shape index (BSI). A high correlation was found among TPH and TAC. In addition, most of cultivars had good adaptation capability and respectable fruit quality attributes, and also had good potential as a commercial crop for fresh and processing markets and future breeding programs.
