Evaluation of the yield and some components in the fruit of blue honeysuckle (Lonicera caerulea var. edulis Turcz. Freyn.)

The experiment was carried out in the Garlica Murowana Experimental Station of University of Agriculture in Krakow, Poland, between 2005 and 2008. Fruit yield, mass of 100 berries, content of total soluble solids, vitamin C, anthocyanins and titratable acidity were estimated. It was shown that ‘Atut’ honeysuckle started vegetation, flowering and cropping periods earlier than ‘Duet’. However, greater marketable yield and mass of 100 berries were obtained for ‘Duet’. ‘Atut’ fruit revealed a significantly higher content of anthocyanins. The studied honeysuckle cultivars did not differ if estimated on the basis of total soluble solids and vitamin C content in the fruit.
