Název v původním jazyce

Evaluation of colour content in grapes originating from south Moravia

Popis výsledku v původním jazyce

The content of total anthocyanins was determined in grapes of nine grapevine (Vitis vinifera L.) varieties belonging to traditional blue grape varieties grown in south Moravia (Czech Republic) within the period of 2002-2007. Factors of vintage and healthcondition of grapes were observed. The material balance of colour substances in grapes was related to the dry matter of skins of berries and that of fresh gapes, which were used as raw material for vinification. The highest content of pigments was foundin the variety Neronet (2.15 -- 4.49 g/kg of fresh grapes), which belongs to the so-called Teinturier varieties. Besides the variety Neronet (containing 30.6 -- 73.4 mg/g of dry skin), high contents of total anthocyanins in dry skins were found in the varieties Dornfelder (24.7 -- 59.0 mg/g of dry skin) and Cabernet Moravia (20.1 -- 59.3 mg/g of dry skin). In the long run, the lowest concentrations of pigments were determined in grapes of the varieties Blauer Portugieser (0.51 -- 1.02 g
