The effects of harvesting at improper maturity on fruit quality and storage life are discussed and minimum maturity indices for selected fruits in California are listed. Most of the currently used maturity indices are based on a compromise between those indices that would ensure the best eating quality to the consumer and those that provide the needed flexibility in marketing. Postharvest ripening is discussed in relation to 2 groups of fruit: (1) fruits that are not capable of continuing their ripening process once removed from the plant, and (2) fruits that can be harvested mature and ripened off the plant. Group 1 fruits produce very small quantities of ethylene and do not respond to ethylene treatment except in terms of degreening; these should be picked when fully ripe to ensure good flavour quality. Fruits in Group 2 produce much larger quantities of ethylene in association with their ripening, and exposure to ethylene will result in faster and more uniform ripening. Flavour quality is dis
cussed and proposed minimum soluble solids content and maximum titratable acidity for acceptable flavour quality of fruits are summarized.
