A comparison of two carbon dioxide-related injuries of apple fruit.

The effects of orchard, CO2 concentration in controlled atmosphere (CA) storage, delaying application of CA storage, and diphenylamine (DPA) application on the development of internal browning (Braeburn browning disorder) in Braeburn apple fruits and an external skin disorder on Empire fruits are described. For both disorders, the extent of disorder development increased as CO2 concentration in the storage atmosphere increased. The sensitivity of fruits to CO2-induced injury was greatest soon after harvest, but declined during CA storage or if fruits were held in air storage before CO2 application. A marked variation was observed in disorder incidence in fruits from different orchards. DPA application (1000 ppm) on the day of harvest prevented the development of external skin injury in Empire apples in CA storage. Recommendations designed to minimize occurrence of the disorders are made and a model is presented which highlights the interactions between pre- and postharvest factors that influence

 the susceptibility of fruits to CO2 injury.
