Late harvest and delayed cooling induce internal browning of 'Ya Li' and 'Seuri' Chinese pears.

Brown discoloration of the core, carpels, and flesh areas of 'Ya Li' and 'Seuri' Chinese pears [Pyrus bretschneideri (Rehd.)] depended on harvest date. Fruit harvested no later than 180 days after full bloom (3000 degree days) did not develop the disorder. Browning of the core and flesh tissues increased when cooling was delayed, but was not influenced by subsequent storage temperatures of 0, 10, or 20 C. In both cultivars, the onset of internal browning was evident after storage in fruit that had been harvested when skin color had changed from green to light green-yellow. Thus, skin color can be used to determine harvest date to avoid internal browning incidence during storage of 'Ya Li' and 'Seuri' Chinese pears.
