Seven cultivars of table grapes were observed with the goal of getting more news about the characteristics of the cultivation, focusing on the evolution of vegetative-productive buds as a function of position along the branch to use. The observations focused on the vitality of the buds and the number of shoots and bunches products. Cultivars ‘Michele Palieri’, ‘Italia’ and ‘Red Globe’ appeared fairly balanced with regard to fertility that is evenly distributed on the vine. In ‘Italia’ grape the high percentage of blind buds on the top positions of the vine could be a problem for the identification of the branches of replacement. Cultivars ‘Victoria’ and ‘Black Magic’, which are characterized by a high fertility index, can be trained with a shorter number of buds per branch. Instead ‘Sublima seedless’ and ‘Superior seedless’, due to low fertility index, need canes with a high number of buds. The different agronomic characteristics of the cultivars highlighted the need of a differentiation in the technical approach for planting patterns and pruning (winter and green).
