| dc.description.abstract | A study of the amount of colouring substance in the skins and juice of grapes and raisins of seedless vine forms with coloured grape juice of six hybrid combinations was performed. It was found that most of the hybrid forms of all crosses were superior to the mother variety Alicante Bouschet in the amount of anthocyanins in the grape juice, and only a few ones have mathematically proven differences. Most of them do not differ from the parent variety in colour intensity and colour shade, as well as in the percentage of yellow, red and blue colour. The ‘Alicante Bouschet’ variety has a proven lower content of anthocyanins in the skins of grapes and raisins of several hybrid forms. There is a proven high or moderate positive correlation between the content of anthocyanins in the skins and the juice of the grapes and the intensity of the colour in the hybrid forms of most crosses. Approximately 47% of the increase in the intensity of the colour of the grape juice can be explained by an increase in the amount of anthocyanins, and only 27% of the reasons for the changes in the intensity of the colour of the grapes are due to factors that do not affect changes in the content of anthocyanins in them. | eng |
