A FRUIT RIPENING MODEL AND STORAGE CHARACTERISTICS OF BLUEBERRY

The rate of maturation and changes in percent soluble solids and rate of decay of three blueberry cultivars, ‘Blomidon’, ‘Northcountry’ and ‘Northland’, under two experimental conditions were studied.
The cultivars reached berry maturity concurrently in about 10 to 26 days from immature green stage.
Berry development from blue-pink to fully mature required about 3 to 6 days.
The percent soluble solids was lower at the green fruit stage than other stages, ‘Blomidon’ was the lowest, reaching 7.3%. From first blue stage to mature, percent soluble solid increased, reaching 14.3%, with ‘Northcountry’ having the fastest rate of increase.
Temperature affected the rate of increase in percent soluble solids and percent berry decay. ‘Northland’ had the highest decay after 12 days of storage at room temperature, 62.3%. The storage life of the three cultivars, from high to low, were in the order of ‘Northland’ > ‘Northcountry’ > ‘Blomidon’.
