firmness at harvest impacts postharvest fruit softening and internal browning development in mechanically damaged and non-damaged highbush blueberries (vaccinium corymbosum l.).	fresh blueberries are very susceptible to mechanical damage, which limits postharvest life and firmness. softening and susceptibility of cultivars "duke" and "brigitta" to developing internal browning (ib) after mechanical impact and subsequent storage was evaluated during a 2-year study (2011/2012, 2012/2013). on each season fruit were carefully hand-picked, segregated into soft (<1.60 n), medium (1.61-1.80 n), and firm (1.81-2.00 n) categories, and then either were dropped (32 cm) onto a hard ...	2017	28443123
evaluation of attractants for monitoring drosophila suzukii (diptera: drosophilidae).	drosophila suzukii matsumura is an economically important pest of soft and small fruit crops. unlike other drosophilid flies, d. suzukii is capable of infesting ripe and partially ripe fruit, which poses a significant pest management challenge, as there is no tolerance for infested or damaged fruit in the marketplace. as a result, producers in many regions rely on calendar-scheduled insecticide applications for d. suzukii management. in order to develop an integrated pest management approach, be ...	2017	28444365
nitrogen-source preference in blueberry (vaccinium sp.): enhanced shoot nitrogen assimilation in response to direct supply of nitrate.	blueberry (vaccinium sp.) is thought to display a preference for the ammonium (nh4+) form over the nitrate (no3-) form of inorganic nitrogen (n). this n-source preference has been associated with a generally low capacity to assimilate the no3- form of n, especially within the shoot tissues. nitrate assimilation is mediated by nitrate reductase (nr), a rate limiting enzyme that converts no3- to nitrite (no2-). we investigated potential limitations of no3- assimilation in two blueberry species, ra ...	2017	28578080
