The applied dose of N was 80 kg ha-1, and the experiment was installed in the Submédio do Vale do São Francisco, Brazil. The experiment was performed in a randomized blocks design, with four treatments and five replicates, with the experimental plot represented by five plants. In addition to the analysis of N, cluster length and width (cm) and fresh mass (g), berries length, diameter (mm), volume (mL), mass of fresh matter of berries, soluble solids (SS), titratable acidity (TA), SS/TA ratio, potential bud fertility (productive, vegetative, dead and dark buds in %) and real bud fertility (%). There were differences in nitrogen content in the leaves, nitrate in sap and CRI of ‘Thompson Seedless’ in relation to rootstocks. ‘Thompson Seedless’ expressed better potential for the development of clusters and berries when grafted on ‘Harmony’.</p></div>
