dc.description.abstractEnBackground and Aims[br/] Both rootstocks and mineral nutrition, particularly nitrogen (N), are known to affect many aspects of plant development including the control of scion vigour. In this study, we investigated the role of the rootstock genotype in grafted grapevine responses to N supply in terms of the root and leaf ionomes, scion vigour and whole plant biomass.[br/] [br/] Methods and Results[br/] Vitis vinifera cv. Cabernet Sauvignon was grafted on two rootstock genotypes known to confer high and low vigour. Plants were grown for 60 days under three levels of nitrate supply. Stem, leaf, trunk and root biomass, and the concentration of 13 macroelements and microelements in roots and leaves were measured. High scion vigour was associated with a high concentration of elements in the leaves. The concentration of some elements in the leaves, such as phosphorus, was affected by the N supply differently in the two scion/rootstock combinations.[br/] [br/] Conclusion[br/] Differences in rootstock conferred vigour were associated with particular shoot and root ionome profiles, and these responses were dependent on N supply.[br/] [br/] Significance of the Study[br/] These results demonstrate that rootstocks alter scion growth and the leaf ionome in response to N supply.
