ABSTRACT



The objective of the study was to determine influence of titanium treatment on selected quality traits of strawberry fruits. The fruit of six strawberry cultivars (‘Dukat’, ‘Elkat’, ‘Elsanta’, ‘Kent’, ‘Selva’ and ‘Senga Sengana’) were obtained from commercial plantation localized near Szczecin. The experiment was carried out in 2004. ‘Tytanit’ spraying (Ti4+ ascorbate) was applied 3 times according to the recommendations for this treatment. Control plants remained not sprayed. The response of the cultivars to titanium was not unequivocal. Positive response was found for ‘Elsanta’, ‘Senga Sengana’, Selva’ and Kent’ berries as far as total anthocyanin content is concerned (increase by 5 - 44%). The treated fruits of ’Selva’ cultivar showed higher values of the all color parametres (L*, a*, b*, C*, h) compared to non-treated berries whereas ‘Kent’, ‘Dukat’ and ‘Senga Sengana’ ones lower. The most stimulating effect of ‘Tytanit’ usage on fruit chemical composition was found for ‘Dukat’ berries. These fruits under titanium treatment showed higher dry weight content, higher soluble solids content, higher titratable acidity and higher soluble solids: titratable acidity ratio compared to non-treated strawberries.

Key words: strawberry, titanium, anthocyanins, fruit color, acidity, soluble solids.
