| Abstract:
In New Zealand, fruit which have passed export packing standards and then been held in storage prior to export are subsequently rejected if they develop botrytis storage rot, fungal or physiological pitting, skin staining, or if they have softened beyond a particular flesh firmness. Recent computerisation of considerable industry information has allowed us to quantify losses according to criteria such as reason for rejection, growing district, fruit size, packing date and length of storage. Losses in the 1989 and 1990 seasons are compared and possible reasons for differences suggested. Observational surveys of individual orchards, packhouses, and coolstores where, historically, fruit has either been badly affected by storage disorders, or has stored exceptionally well, are being undertaken to identify factors which may contribute to these disorders. | |
