| Abstract:
Muscat rose of Porec has a functional pistillate inflorescence so that the pollination has to be done by other cultivars. The research was carried out on the old plantation “Ticarica” in the period 1995 – 1996. The influence of three pollinators (Merlot, Teran and Borgonja) on the yield and grape quality of Muscat rose of Porec was investigated. The vines pollinated by Borgonja gave the highest yield, followed by those pollinated by Teran and finally by those pollinated by Merlot. In vines pollinated by Borgonja and Teran big and middle big berries predominated. Most of the vines pollinated by Merlot had thin clusters, while most of those pollinated by Borgonja and Teran had middle compact clusters. The must from the vines pollinated by Merlot had the highest sugar and the lowest acid contents; that from the vines pollinated by Borgonja the lowest sugar and the highest acids contents and that from the vines pollinated by Teran had middling sugar and acid contents. All three tested cultivars are suitable as pollinators for Muscat rose of Porec. | |
