WSU-TFREC POSTHARVEST INFORMATION NETWORK DEVELOPMENT OF INTERNAL BROWNING IN FUJI APPLES DURING STORAGE

Fuji apples may develop the physiological disorders core flush or flesh browning during cold storage in air (RA) or controlled atmosphere (CA) (Argenta et al., 2000). Core flush is a symptom of senescence characterized by yellow-brown discoloration in the core (Wilkinson and Fidler, 1973). In Fuji apples, flesh browning (Photo 1) resembles senescent breakdown because the diffuse, light brown discoloration develops initially in the outer portion of the cortex tissue and is often associated with browning of the vascular tissues. The primary factor leading to development of harvest and extended storage of over-mature fru 1994). Delaying cold storage, watercore, low ca cool temperatures accentuate development of se and flesh browning are more likely to occur when One means to reduce the risk of core flush and late harvest fruit with severe watercore.
