Abstract
The aim of this study was to compare the value of Senga Sengana, a long-term standard cultivar, with other cultivars grown in northwest Poland, namely Dukat, Elkat, Selva, Elsanta and Kent. The fruits were obtained from a commercial plantation and cultivated by applying conventional farming practice. Among the strawberry cultivars studied Elsanta berries had the highest vitamin C content and its leaves the highest ellagic acid content. Kent berries had the highest contents of total sugar, total polyphenol, total anthocyanin and ellagic acid derivatives. Dukat berries had the highest dry weight and soluble solids content. Senga Sengana berries had a slightly higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging effect than other cultivars. Consumer-objective colour measurements were performed to evaluate the quality of the fruit. Elsanta and Elkat berries were found to have the highest L (lightness), a* (redness), C* (chromaticity) and h (hue angle) values.
