This talk was given at a local TEDx event, produced independently of the TED Conferences. In an increasingly competitive fresh cherry market, buyers are looking, above all, for consistent, reliable quality.
That means growers must be able to deliver the same quality day after day so that buyers develop a trust and come back for more. Quality fruit has a low incidence of defects, such as pebbling, pitting, stem browning, shrivel, decay, and softening, and is not infested by insects. Above all, the cherries must be firm. 

Dr. Peter M.A. Toivonen is a Postharvest Physiologist, who from 1989 has been working with Agriculture and Agri-Food Canada at the Pacific Agri-Food Research Centre in Summerland, British Columbia, Canada. He has had responsibility over a varied series of research topics ranging from vegetables, to small fruits, fresh-cut fruits and vegetables and tree fruits (sweet cherries, apples, and stone fruits). Dr. Toivonen is the current vice-chair for the ISHS Commission Quality and Postharvest. His current research activities are; 1) implications of wound-associated metabolism on the microbial safety of fresh-cut vegetables, 2) phenotyping of new apple and sweet cherry cultivars for postharvest characteristics, and 3) logistics and quality management of sweet cherries destined for containerized sea shipment. 

About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
