The present paper shows the results of a study on the effect of freeze and thermal drying on the content of organic acids and flavonoids in fruit of European cranberry (Oxycoccus palustris Pers.). They indicate a significant effect of drying conditions on the content of the above mentioned active compounds. In lyophilized fruit, distinctly more organic acids but less flavonoids were found than in fruit dried at a temperature of 35–400 C. The largest relative differences were observed in the case of ascorbic acid. Its content in the fruit dried at high temperature, compared to the lyophilized material, was lower by a mean value of 5 mg/100 g of dry matter (DM), that is, by 42% on the average. With regard to the other organic acids (quinic, citric and malic acids), the average difference was 0.9–2.1 g/100 g DM (14–17%). The mean flavonoid content in the thermally dried fruit was larger by 34 mg/100 g DM (converted into hyperoside) and 24 mg/100 g (converted into quercetin), that is on average by 19% as compared to freeze-dried samples.

The wild-harvested fruit of Vaccinium oxycoccos (European cranberry) is used medicinally in many European and North American countries; the plant, however, is seldom cultivated. In order to optimize the collection strategy and improve the horticulturally important characters of V. oxycoccos clones, comprehensive investigations of the species are necessary. In the present study we investigated the phenological, morphological and genetic diversity of 29 clones originating from two wild populations growing in two strictly protected Lithuanian reserves, Čepkeliai and Žuvintas. During an ex situ collection at Kaunas Botanical Garden, we observed great phenological variation between the collected V. oxycoccos clones. The following morphological traits most clearly distinguished our study clones: leaf size, berry shape, berry size and fruit colour at full maturity. The genetic variation of V. oxycoccos clones from the two populations was assessed using RAPD and SSR. RAPD analysis conducted with 9 primers resulted in 146 polymorphic loci for the total sample, and SSR analysis with 5 primers revealed 29 alleles for the total sample. A greater degree of polymorphism was demonstrated for the Čepkeliai population than for the Žuvintas population. The study allowed the selection of several clones having promising morphological traits for further testing in the field.

The aim of this study was to determine fruit yield of Oxycoccus palustris under the climatic and habitat conditions of northern Wielkopolska (the Greater Poland region), depending on the type of occupied plant community. Total fruit number and fruit weight as well as average cranberry leaf size were determined on 33 plots with an area of 1 m2, located on 7 peatlands. On the study areas, European cranberry produced crops from 9.2 up to 242.0 g x m -2, which gives 92-2420 kg x ha -1. It has been demonstrated that on the peatlands of northern Wielkopolska O. palustris reaches its generative and vegetative optimum in the communities of the class Scheuchzerio- Caricetea fuscae, in particular in the community Sphagno recurvi-Eriophoretum angustifolii.
