Popis: Registrations of crop, fruit size and fruit flavour in the plum cultivar testing programmes in Norway indicated that Souffriau, Avalon, Reeves, Excalibur and Jubileum could be valuable cultivars in commercial plum production in Norway. Norwegian plums are aimed at the fresh fruit market; hence, shelf life of new cultivars is very important. In short-term storage experiments the cultivars were compared to the standard cultivar Victoria. No significant changes in the content of soluble solids during storage were found in the cultivars tested; however, titratable acidity decreased, and as a consequence, the soluble solids:titratable acidity ratio increased. Nevertheless, these changes did not make the fruit unacceptable to consumers. The most important quality factor limiting shelf life of the plum cultivars tested was softening. Based on postharvest changes in several quality factors and susceptibility to fungal decay, Reeves had longest shelf life, Avalon, Jubileum and Victoria medium, while Excalibur and Souffriau had rather short shelf life.
