Postharvest factors influencing stem-end rind breakdown of 'Valencia' oranges.

Auteurs : DOU H. T.

Résumé

Severe stem-end rind breakdown (SERB) of "Valencia" oranges (Citrus sinensis) exported from Florida to the Republic of Korea and Taiwan has been reported in recent years. The effects of clipping versus pulling, coating application, storage temperature, and fruit size on SERB of 'Valencia' oranges were studied during the 1998-1999 and 1999-2000 seasons, in Florida, USA. These studies demonstrated that storage temperature is the most significant factor influencing SERB of "Valencia" oranges. Three weeks after packaging, fruit stored at 21 °C with 70 plus or minor 3% relative humidity (RH) had 61% SERB, while fruit stored at 4 °C under the same RH had only 1.3% SERB. Coating application and formulation did not result in consistent effects on fruit SERB incidence. Fruit size and harvesting methods (pulling versus clipping) did not significantly influence the incidence of fruit with SERB symptoms.
