Harvest maturity, packaging and storage time related to calyx-end rot expression on Packham's Triumph pears under refrigerated storage.

The time of symptom expression of calyx-end rot (caused by Botrytis cinerea) in Packham's Triumph pears, coming from a high (H1) or low (H2) disease incidence forecasted orchards and harvested at 18 lb (M1) or 15 lb (M2) of flesh firmness, was determined during a 150-day period of cold storage. No effects were found on pears coming from H2 orchards, where disease incidence was exceptionally low (0.9% as mean for all treatments). For H1, significant fruit rotting in M1 pears occurred after 90 days of storage at -0.5 deg C, while M2 pears showed the same at 45 days. Therefore initial maturity had a determining effect on the level and time of expression of calyx-end rot. The type of packaging used (wood or pulpboard containers) did not affect disease development. Calyx-end rot was significantly correlated with flesh firmness and soluble solids changes during storage.
