In the present work determinations were made regarding the behavior of wine grape varieties 'Aromat de Iași’ and 'Golia’, respectively Chasselas doré variety, that was taken as control, grafted on three rootstocks Riparia Gloire, Berlandieri x Riparia Selection Oppenheim 4-clone 4 Blaj and Berlandieri x Riparia Selection Crăciunel 2. It was found that the highest total content of carbohydrates had the rootstock Riparia gloire (13.49%), followed by Crăciunel 2 (12.78%) and SO4-4 (12.02%). In the Vinifera varieties the same indicator was higher for 'Golia’ grape variety (15.64%) and for 'Aromat de Iași’ variety (14.97%), compared to the control variety Chasselas doré (13.83%). As a result of the grafting and forcing, the following aspects resulted: the percentage of vines suitable for planting was the highest in the 'Golia’ variety grafted on Riparia Gloire, respectively 98%, and in the 'Aromat de Iași’ variety grafted on Crăciunel 2, of 96%. The vines for which the grafting point was complete, where the buds entered vegetation and the root primordia was in maximum percentage were found at the 'Golia’/SO4-4 variant, at 74%.
