This research was conducted in 2014 at the Department of Horticulture of Mustafa Kemal University.’Ora’, ‘Prima’, ‘Early Sweet’ grape cultivars were grafted on ‘41B’, ‘SO4’ and ‘1103 P’ American rootstocks using omega (Ω) grafting method. Ambient temperature and humidity values were recorded during the term of the trial. Bud burst ratio (%), callus formation ratio (%), callus formation degree , rooting ratio (%), rooting degree , first grade grafted vines (%), shoot length (cm) and shoot diameter (mm), shoot node number (n), mean leaf area (cm2), total leaf area (cm2), total dry weight (g), chlorophyll content and nutrient element (N, K, Mg, Ca, Fe, Mn) content were analyzed in the research. Differences were observed between rootstocks and cultivars on the basis of analyzed characteristics. 1103 P rootstock yielded higher values than 41B and SO4 rootstocks in terms of bud burst ratio, callus formation ratio, callus formation degree, total leaf area, rooting ratio. 1103 P (88,89%) was found to be significantly higher in terms of first grade grafted vine ratio than 41 B (61,11%) and SO4 (51,11%) rootstocks. While the influence of rootstocks were not found to be significant in terms of Mg, Ca in nutrient element content of cultivars; statistical differences were observed in terms of N, K, Mn contents
