Characterization of fruit quality attributes and nutritional composition of ten blueberry cultivars

What is it about?

A study was conducted to characterize fruits of 10 blueberry cultivars cropped in field of south-central Chile, according to firmness, weight, caliber, macronutrient content, anthocyanins, titratable acidity, and soluble solids. Value ranges for each of the characterized fruit parameters varied between 12.89 and 18.68 °Brix for soluble solids, 0.57% and 0.79% for titratable acidity, 57.0 and 81.6 g mm-1 for firmness, 1.74 and 2.80 g for average fruit weight, 14.7 and 17.9 mm for average fruit diameter, 1.80 and 15.55 mg L-1 for anthocyanins, and 14.4% and 21.6% for dry matter content. Fruit nutrient concentration (mg 100g-1 fresh fruit) were ranged from 63.6 to 104.0 mg N 100 g-1, 7.0 to 12.2 mg P 100 g-1, 76.4 to 122.7 mg K 100 g-1, 4.5 to 9.8 mg Ca 100 g-1, 3.6 to 6.9 mg Mg 100 g-1, and 3.7 to 5.8 mg S 100 g-1. The cultivar with the highest overall values for fruit characterization was ‘Last Call’, while the cultivars with the lowest values were ‘Brigitta’, ‘Liberty’, and ‘Cargo’.
