ABSTRACT

The aim of study was to compare fruit weight, firmness, chemical composition and fruit colour of 14 blue honeysuckle (Lonicera caerulea L.) cultivars and clones collected at the beginning and end of the harvest season, respectively. Blue honeysuckle is a species of early maturing fruits but they usually characterised by lower quality. Among all the tested cultivars the fruits of 'Zielona' and ‘Brązowa’ have been characterized as the earliest and the latest ripening, respectively. The first ripening fruits of all cultivars were smaller than those collected in the subsequent period. At the initial harvesting period, the 'Duet' cultivar had the largest fruits, 100 fruits weighed 115 g. However, the 'Dlinnoplodna' fruits weighed 37 g and the fruits were also characterized by low firmness. Towards the end of the fruit-bearing season, fruits collected from 'Czarna' cultivar shrubs and the Clone A1 weighed up to 151 g. Fruits collected towards the end of the ripening season had a significantly higher content of the extract (11.3%–16.7%) and lower acidity (1.5%–2.9%) than fruits collected at an earlier vegetative stage, what influenced by the increase of air temperature by 6.2°C. The research also revealed considerable variation of the fruit colour of the cultivars under analysis and considerable differences between the fruit colour and the berry wax deposition and the basic colour of the fruit surface.

Key words: Lonicera caerulea, cultivar, fruit size, chemical composition, fruits color.
