Influenza del confezionamento con film plastico sulla maturazione di frutti di avocado (Persea americana Mill.) cv Hass frigoconservati.

Hass avocado fruits were harvested in mid-April from a commercial orchard in E. Sicily. The fruits were transported under non-controlled conditions to Sardinia, sorted and were either wrapped individually in polystyrene trays with a 15-mm-thick polyolefinic heat shrinkable film or not wrapped, before being stored at 4 deg C and 90% RH for 0, 2, 4, 6 or 8 weeks. At the end of each storage period, when the fruits were transferred at 20 deg C for ripening, a sample was unwrapped, while another sample was unwrapped after 3 days of exposure to 20 deg C. Film wrapping was not effective in prolonging postharvest life of Hass avocado fruits by slowing their physiological activity, but was very effective in reducing chilling injury, as evidenced by the negligible incidence of internal browning, increased ethylene production and the shorter time required to ripen following 4 weeks of storage, when the severity of chilling injury became apparent.
