Preharvest effects on postharvest quality of subtropical and tropical fruit.

ABSTRACT

Preharvest factors can influence most, if not all, quality parameters. The effects preharvest factors can have on visual appearance (size, colour, blemishes), eating quality (flavour, texture), storage potential (ripening, physiological disorders, disease), and tolerance to physical disinfection and disinfestation control measures (heat, cold) are presented for subtropical and tropical fruits. General relationships are noted in temperate and tropical fruits between nitrogen and colour, disorders and postharvest disease incidence; fruit size and firmness, calcium and disorders; calcium and ripening, disorders and disease incidence; and between calcium, magnesium and potassium. Ways of improving storage potential through altering fruit mineral content are discussed. Such improvements could result in reduced postharvest inputs (storage and disease control). There is potential for predictive models for storage potential of tropical fruits based on minerals, as currently exists for disorder predictio

n in apples. However, consideration should be given to the interactions between management practices and the various balances that exist in plants, and the compromises often required for producing a quality product.
