Research was carried out to determine the effect of rootstocks (41B, Ruggeri 140, SO4 and Fercal) on petiole macro-element content (nitrogen, phosphorus, potasium, calcium and magnesium) of three grape scion cultivars (‘Halawani’, ‘Baladi’ and ‘Bayadi’). In the first year, rootstock had significant effect on petiole nitrogen content, while in the second year the differences were not significant. Conversely, the scions significantly affected nitrogen in both seasons. Rootstocks increased the levels of phosphorus in petioles compared with control (own rooted) plants. Vines grafted onto the rootstocks Ruggeri 140 and 41B had significantly higher petiole phosphorus content than those on their own roots. Scions had no effect on phosphorus concentrations, but had an effect on potassium concentrations. Petiole potassium levels increased significantly on all cultivars grafted to SO4. There were significant differences of calcium and magnesium contents of petioles among rootstocks and scion cultivars. Petioles of own-rooted plants and SO4 rootstock had the highest calcium concentration, whereas the lowest calcium levels were Ruggeri 140 and 41B in the investigated three cultivars. Petiole magnesium contents were greater for vines on Ruggeri 140 than for vines on SO4 and Fercal, whereas own-rooted plants had intermediate levels of magnesium.
