Abstract

Winter injury to branches of highbush blueberries (Vaccinium australe Small cv. Jersey) resulted when mechanical harvester use caused lesions on the branches during the harvesting process. Of the dead wood collected during 2 years study, more than 99% had such a lesion. The amount of wood lost increased as the vibration rates of the harvester increased and at high rates loss of bearing surface reduced production the following season.

Abstract

Application of (2-chloroethyl)phosphonic acid (ethephon) reduced fruit removal force (FRF) as much as 50% depending on concentration and time of application. Reduction in FRF allowed reduced mechanical harvesting vibration frequency which reduced damage to berries during harvest and thus increased shelf-life. Mechanical harvest was further facilitated by ethephon-induced color development and hastening of abscission which reduced the number of machine harvests required.
