The basic chemical parameters of berries from some white currant cultivars

In this theses the author deals with a chemical analysis of juice from cultivars of the white currant (Ribes vulgare). The theoretical part explains the taxonomic classification and botanical characteristics of the white currant including the genus of Ribes, also its spread and habitat. The thesis also refers to the history, the growing of the currant, its prune and planting, as well as the propagation and cultivating of its particular cultivars. There are also mentioned diseases and pests which the currant suffers from. The cultivars of the white currant, which were used in an experimental part, are described primarily thoroughly. In the experimental part there was the determination of chosen chemical analysis conducted, for example the yield, the content of the dry matter, pH, titratable acidity, the formol number, the content of reducing sugar and the dry matter in the fruit of eight cultivated cultivars of the white currant. The cultivars were compared with each other. Than the highest and the lowest value of the analysis was evaluated
