| Abstract:
The name of the grapevine cultivar ‘Kéknyelű’ has become inseparable from the name of the Badacsony vine region, it’s fame is well known beyond our frontier as well. ‘Kéknyelű has a functional female flower, and because of it, the pollen is sterile. In the Internet, we find on the Vitis International Variety Catalogue site (http://www.genres.de/idb/vitis/), the ‘Kéknyelű’, as the synonym of the Italian grapevine cultivar ‘Picolit’. In the morphological description, we find that this cultivar has – as the ‘Kéknyelű’ – functional female flowers, but the shape of the mature leaves of the two cultivars differs. Vertical poliacrylamide-gel electrophoresis was used for the investigation of catechol-oxidase (CO) and acid phosphatase (AcP). The results of the isoenzymatic analyses confirmed, that this two cultivars are different. | |
