Inter- and intra-seasonal changes in anthocyanin accumulation and global metabolite profiling of six blueberry genotypes

Effect of postharvest application of ethylene on the profile of phenolic acids and anthocyanins in three blueberry cultivars (Vaccinium corymbosum)

“…In ‘Ozarkblue,’ seven anthocyanins (delphinidin 3‐O‐galactoside, cyanidin 3‐O‐galactoside, cyanidin 3‐O‐glucoside, cyanidin 3‐O‐arabinoside, malvidin 3‐O‐galactoside, malvidin 3‐O‐glucoside, peonidin‐3‐O‐galactoside) and the same two hydroxycinnamic acids were identified. Timmers et al, Pertuzatti et al . and Bunea et al .…”

“…Genetic factors predispose certain cultivars to accumulate higher levels of anthocyanins, thus several researchers also found that different cultivars of blueberries showed different anthocyanins profiles. However, Lohachoompol et al, when they studied three blueberry cultivars, found that the anthocyanin profile was similar in all cultivars, but the proportions of each compound were cultivar dependent.…”

“…The sensory panel did not identify significant differences in ethylene treated fruits compared to untreated ones for the different qualitative descriptors such as exterior color, 'off' odors, flavor, 'off' flavor, resistance to breaking the cuticle, total hardness of the fruit, sweetness, and astringency (Figs 2(a)-(c)). 21 Pertuzatti et al 23 and Bunea et al 46 also observed that anthocyanins were derived from five Genetic factors predispose certain cultivars to accumulate higher levels of anthocyanins, thus several researchers 21,23,46 also found that different cultivars of blueberries showed different anthocyanins profiles. However, Lohachoompol et al, 47 when they studied three blueberry cultivars, found that the anthocyanin profile was similar in all cultivars, but the proportions of each compound were cultivar dependent.…”

“…18 Several authors observed remarkable differences in individual anthocyanin content among different blueberry cultivars and products. [20][21][22][23][24] For example, Rabbiteye genotypes (Ira, Montgomery, and Onslow) contained higher percentages of cyanidin glycosides than the southern highbush genotypes (Legacy, Sampson, and SHF2B1-21:3) whereas the reverse was found for the levels of delphinidin glycosides present. 21 Muller et al also found that the anthocyanin profiles of blueberry fruits and juice or nectar were similar; however, the amount was lower due to different causes such as the conditions of fruit production, the state of maturation of the harvest, or the methodology used to make the juice.…”

“…So ‘Climax’ fruits that were organically grown showed a lower chlorogenic acid (13.84 ± 2.12 mg/100 g fresh weight) than the same cultivar conventionally grown (17.81 ± 0.31 mg/100 g fresh weight) .
