The potential growth, yield and grape quality cv. ‘Plavac mali’ (Vitis vinifera L.) under conditions of meliorated karst

In the last decade, the most common autochthonous species of the Adriatic coast ‘Plavac mali’ is planted in new locations and in substrates that differ from traditional vineyards. In order to investigate the specificity of the substrate of meliorated karst on the vegetative potential as well the quantitative and qualitative components of the grape a study was carried out in the vineyards on the meliorated karst at the position "Dingač" and "Rota". The average yield was higher in vineyards on meliorated karst. It has been found the vegetative growth potential is balanced. The results for the average mass of the cluster show an exceptionally high variability where recorded unusually low values of this parameter on the meliorated karst. The average sugar contents are higher in grapes from traditional vineyards compared to grape on meliorated karst.
