Maturity and water loss effects on avocado (Persea americana Mill.) postharvest physiology in cool environments.

The influence of cold storage, increasing fruit maturity and water loss on the ripening physiology of Fuerte avocado was investigated. Fruits cold-stored for 28 days at 5.5 deg C always subsequently ripened faster than non-stored fruits of a similar maturity. Non-stored fruits showed an expected decrease in ripening time with increasing maturity. In cold-stored fruits the relationship between ripening time and maturity was less clear. Cold-stored fruits lost less water during ripening than non-stored fruits of similar maturity, but lost water faster than non-stored fruits. The total amount of water lost during ripening decreased as fruits matured. Cold storage increased the incidence of mesocarp discoloration which became more severe with increasing fruit maturity. Passive water infusion into fruits had no effect on the rate of fruit ripening (and water is obviously not involved as a ripening trigger) but totally inhibited the manifestation of postharvest browning disorders.
