Quality problems in important fruit crops in ASEAN

Abstract

Quality problems which diminish the competitiveness of ASEAN fruits in target export markets include decay and physiological disorders. Latent diseases originate in the field, but become evident only after harvest. Factors which induce physiological disorders, on the other hand, are principally postharvest in origin. However, predisposing conditions might occur during fruit growth and development. Fruit crops important to ASEAN include the banana, pineapple, mango, rambutan, papaya and durian. Although disease problem, principally, anthracnose and stem end rot constitute a major problem in these fruits, causative organisms have been identified and control measures formulated. In contrast, physiological disorders, which lead to quality deterioration arid limit the marketable life of these fruits, are not as well understood. Hypoxia, particularly if combined with threshold levels of ethylene and temperature extremes can lead to a variety of these disorders. Quality problems arising from physiological disorders of mango, rambutan, papaya and durian, as well as etiological aspeCtS are discussed.
