"Tardivo di san Vito" orange fruits, a local late ripening cultivar, were cold stored. Harvesting took place in
the second half of April from trees grafted on sour orange at the experimental station of CNR at Oristano. Fruit
were selected for minimal blemishes and size and randomly divided in two plots before being cold stored at 3 or
8°C and 95% of relative humidity (RH) for 12 weeks. Fruits were transferred to 20°C and 70% RH after 6 and
12 weeks of cold storage to simulate shelf-life (SL). Fruits were inspected at harvest and at the end of both cold
storage and SL periods for the following parameters: overall appearance, main chemical parameters (pH,
titrable acidity, total soluble solids, ascorbic acid). Percent weight loss, decay and chilling injury incidence were also recorded at the above cited inspection times, except harvest.
Results clearly indicate that "Tardivo di San Vito" orange fruit can withstand the lowest storage temperature
of this trial. In fact, fruits show an excellent resistance to pathological breakdown, to chilling injury and
maintain a good quality during the whole storage period.
