The effect of delaying harvest date on fruit quality and storage of late highbush blueberry cultivars (Vaccinium corymbosum L.)](/preview/png/4518339.png)
• The fruit of some cultivars were less influenced by overall crop ripeness than others.
• It is possible delay harvest without a loss in post-harvest storage life and an improvement in flavor.
• It is possible to use some physiochemical measurements to predict consumer flavor acceptance.
The effect of delaying harvest on fruit quality and storage life was measured for the late-season highbush blueberry cultivars ‘Aurora’, ‘Elliott’ and ‘Liberty’. In all three cultivars as fruit ripened, there was a steady decline in TA while SS remained stable, indicating that the fruit were becoming sweeter. This was supported by taste panel perceptions of greater sweetness associated with later harvested fruit. There was also a significant overall reduction in fruit firmness and storage life as the percentage of blue fruit at harvest increased; however, a significant interaction for storage life between crop ripeness and cultivar was observed, indicating that the fruit of some cultivars were less influenced by overall crop ripeness than others. The storage life of ‘Elliott’ was significantly affected negatively by crop ripeness, while ‘Aurora’ and ‘Liberty’ were not. ‘Liberty’ produced the highest percentage of sound fruit of the three cultivars and its fruit stored the longest, suggesting that ‘Liberty’ and ‘Aurora’ fruit can be left longer on the bush before harvesting than ‘Elliott’ without significantly damaging storage life. This would allow ‘Aurora’ to develop a sweeter flavor before shipping. The physicochemical and sensory evaluations were highly correlated, suggesting that TA, SS and firmness can be used as predictors of consumer preferences.
