Postharvest Physiology and Handling of PNW Pears – Wenatchee

July 19, 2016 @ 12:00 pm - 2:00 pm

View Print Version

Pear storage life is limited under conventional storage conditions, which narrows their marketing period. The onset of physiological disorders like superficial scald and core breakdown, ethylene production and delayed harvest are some factors that can affect storage life of the fruit; thus, technologies like refrigeration, controlled atmospheres and the application of some products have been extensively studied to reduce fruit losses.
The application of 1-methylcyclopropene (1-MCP) has shown inconsistent effects on pears, which has led to disagreement within the tree fruit industry over its use and benefits. To this end, research is necessary addressing the physiology of pear ripening and the appropriate timing for Harvista/1-MCP applications.
Dr. Yan Wang, from Oregon State University, has done extensive work on pear storage and will deliver a presentation on “Postharvest Physiology and Handling of PNW Pears” at two separate locations/dates: Yakima (July 18) and Wenatchee (July 19).

Topics that will be covered include:

– 1-MCP and Anjou pear scald and ripening capacity
– Extending storage quality of Bartlett, Bosc, and Starkrimson
– Major PNW pear storage disorders and decays observed in recent years.
