Surface Pitting—a Storage Disorder of Sweet Cherries

Abstract

A storage disorder of sweet cherries referred the disorder than storage at a temperature to as surface pitting is described and illus-several deglees higher. Neither mineral foliar trated. Differeni handling, packaging and stor-sprays nor controlled atmosphere storage age treatments influenced the amount of the were effective in preventing surface pitting, disorder, but did not prevent it.

Evaluation of induced pitting damage of late season cherries ‘Regina’ and ‘Sweetheart’ using an impact energy method

“…Wade and Bain (1980) mention surface pits to occur when cells in the hypodermis and first layer of mesocarp collapse. Literature defines two different types of pitting: the damage that occurs when enough pressure is applied gradually (compression), and the one that occurs instantaneously (impact) (Porritt et al, 1971;Facteau and Rowe, 1979).…”

Resistance of sweet cherry cultivars to fruit surface pitting

“…However Facteau et al (1987) reported that there was no reduction of FSP as a result of CaCl 2 sprays. Warmer fruit that was handled or sent through packing lines developed less FSP than cooler fruit (Lidster and Tung 1980;Kupferman et al 1995;Porritt et al 1971). Thompson et al (1995) reported that shower-type hydrocoolers with high water drop heights cause FSP as does dropping cherries 25 cm on to a cleated conveyor belt.…”

“…Mitcham et al (2002) describe FSP as an indentation in the surface of the fruit caused by the collapse of cells under the skin. The injury appears to occur during either the picking or sorting and packing processes and then develops in storage (Porritt et al 1971). Facteau and Rowe (1979) reported that percent soluble solids and fruit weight were negatively related to the amount of FSP in Lambert.…”

“…The disorder appears as one or more irregular depressions in the surface of the fruit and can occur anywhere on the fruit (Porritt et al 1971). The depressions vary in size from about 4 to 8 mm.…”

“…They further reported that FSP was found in cherries from each of four cherry-growing regions, that is Washington, California, Oregon, and Chile. FSP can also be a problem in cherries produced in British Columbia (Porritt et al 1971).…”
