Abstract
The article is dealing with evaluation of four fruit maturity stages of 6 selected clones (LKL-3, LKL-14, LKL-19, LKL-33, LKL-96 and LKL-103) of Lonicera kamtschatica (Sevast.) Pojark in relation to total polyphenols, flavonoids content and antioxidant activity of berries. The experiment in 5 replications of each clones has been established in the conditions of Botanical Garden in Nitra (Slovak republic)in 2016. The results of analyses proved that in respect of the total polyphenols content (TPC), the content of flavonoids (FC) and the antioxidant activity the most valuable clones at the stage of full ripened fruit were following: LKL-14 (8.77; 2.57 g/kg FW; 9.07 g/kg), LKL-33 (6.77; 2.84 g/kg FW; 9.16 g/kg) and LKL -3 (8.19; 2.61 g/kg FW; 8.94 g/kg). The results of statistical analyses by one-way analysis of variance proved significant differences among assayed clones in total flavonoids and antioxidant activity of fruit but no differences among content of total polyphenols and assayed stages of fruit maturity.
