Postharvest pitting of 'Fallglo' tangerine.

The morphology and aetiology of postharvest pitting of peel of the citrus hybrid cultivar Fallglo (Bower citrus hybrid (Citrus reticulata x C. reticulata x C. paradisi) x Temple (C. reticulata x C. sinensis)) were determined. The disorder was characterized by scattered collapse of the flavedo that resulted from necrosis of cells within and enveloping the oil glands. In severe cases, damage occurred in epidermal and hypodermal cells above collapsed oil glands and surrounding vascular tissues, but cells between oil glands were often undamaged. Pitting was caused by storing waxed fruits at high temperature (more than or equal to 15.5 deg C), but was not affected by ethylene exposure during degreening. Fruits coated with commercially available shellac- and polyethylene-based waxes pitted more than fruits coated with carnauba-based waxes. Pitting was controlled by not coating fruits with wax or by storing fruits at low temperatures (4.5 deg ) within hours after wax application.
