“…For example, the firmness of blueberries could be improved by cultural management practices such as calcium application (Stuckm'ath et al. 2008: Hanson et al, 1993. It has also been demonstrated that firmness of blueberries can be improved by using plant hormones or growth regulators (NeSmith, 1999).…”

Berry firmness and total soluble solids (TSS) of three newly released highbush blueberry cultivars ('Draper', 'Liberty', and 'Aurora') were evaluated in the 2005 growing season against three popular commercial highbush cultivars ('Duke', 'Bluecrop', and 'Elliott') grown in the Northwest during and after cold storage at temperatures between 1 to 4'C. These experiments were conducted using berries from the first pick in a variety evaluation plot at the North Willamette Research and Extension Center. Berry firmness was determined with a FirmTech II firmness tester. After cold storage durations of 1, 2, and 3 weeks, berries were taken out and acclimated at room temperature. Berry firmness and TSS then were determined every three days until berries were considered unmarketable. At week 1, 'Draper' and 'Duke' had the highest firmness in the first three days, and 'Elliott' and 'Liberty' had the lowest firmness during the 12 days sitting at room temperature. 'Liberty' had the highest TSS among all cultivars. At week 2, 'Duke' had the highest firmness while 'Elliott' had the lowest firmness during the 12-day period. For TSS level, 'Bluecrop' was the lowest and 'Elliott' and 'Liberty' were the highest. At week 3 during the 12day test period, the cultivars with the highest and lowest firmness were 'Duke' and 'Elliott' respectively. TSS in 'Liberty' was still among the highest, and 'Bluecrop' and 'Liberty' had the lowest TSS level among all cultivars. If shelf-life is measured by berry firmness at room temperature, the shelf-life of 'Duke' and 'Draper' were very similar. 'Aurora' had a shelf-life better than 'Elliott'; however 'Liberty' had a shelflife no better than 'Bluecrop'.

“…Fruit homogeneity is essential to obtain high quality produce, firmness being one of the most critical attributes influencing consumer acceptance (NeSmith et al, 2002). Firmer fruit will better stand harvest and postharvest management (Hanson et al, 1993). Shippers have reported that the rate of non-accepted Chilean fruit at destination has increased during the last decade.…”
