Summary

Mature-green 'Bartlett' pears (Pyrus communis L.) were harvested weekly during the commercial harvest period to explore the influence of three climatically diverse growing locations and of harvest maturity on the requirement for ethylene treatment at harvest to achieve uniform ripening and good eating quality. Pears were treated with ethylene or air (untreated) at 20 °C for 24 h to determine their responsiveness to ethylene, including the effect on 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase activity during subsequent ripening at 20 °C. Pears harvested from warmer growing regions as well as early harvests from later growing locations which experience cooler preharvest night temperatures can benefit from treatment with ethylene after harvest to promote uniform ripening.
