Effect of fruit maturation on sugar and organic acid composition in two blueberries (Vaccinium arctostaphylosandV. myrtillus) native to Turkey

Methyl jasmonate affects phenolic metabolism and gene expression in blueberry (Vaccinium corymbosum)

“…Sugar levels may influence the accumulation of flavonoid compounds so we decided to investigate whether there were differences in sugar levels between the cultivars, during fruit ripening as well as after MeJa treatment. The levels and ratios of total sucrose, reducing sugars and total sugars are consistent with previous published data for Vaccinium species (Taulavuori et al , Ayaz et al ). Previous studies showed a role for sucrose in affecting the accumulation and regulation of anthocyanins (Loreti et al , Payyavula et al ).…”

Quality factors, antioxidant activity, and sensory properties of jet‐tube dried rabbiteye blueberries

“…As expected, the sugar content of ‘Brightwell’ cultivars increased throughout the season, rising from 10.9 °Brix for early‐harvested berries to 13.0 °Brix for mid‐season berries and to 13.9 °Brix for late‐harvested berries. It has been reported that the total sugars in two Vaccinium varieties increased from 350 to 630 g kg −1 dry weight during ripening, with the predominant simple sugars being fructose, glucose, and sucrose . Ripe highbush ‘Bluecrop’ blueberries were reported to have sugar levels of 15.1 °Brix …”

Effects of latitude and weather conditions on sugars, fruit acids and ascorbic acid in currant (Ribes sp.) cultivars

“…Species‐specific characteristics in malic acid metabolism have been reported in many fruits. For example, malic acid has been shown to accumulate in nectarine,25 medlar,26 cherry27 and blueberry28 but to decrease in peach,29 loquat30 and damson plum31 during fruit development and ripening. Genetic studies have shown that the accumulation of malic acid and citric acid is controlled by the genes of related enzymes, which vary between species and cultivars 29, 32–35.…”
