The objective of the present investigation is the content of basic mineral nutrients in sweet cherry leaves related to both the cultivar/rootstock combination and the stage of vegetation. Subjects of study were the Bigarеаu Burlat and Regina cultivars grafted on three rootstocks with different vigor: Prunus avium seedling, Gisela 5 clone and Camil clone. The trees were supplied with water by a drip irrigation system, which was also used for application of fertilizers. Leaf samples were collected on a monthly basis during the vegetations of 2006 and 2007 and were analyzed for N, P, K, Ca, Mg and Fe. The results outlined common for most fruit species tendencies of decreasing of N, P and K and increasing of Ca and Mg in the leaves with the progress of the vegetation. The uptake of mineral nutrients was influenced rather by the cultivar-rootstock combination than by the cultivar and the rootstock themselves. Bigarеаu Burlat x Camil was distinguished by its low uptake of almost all analyzed elements, which might be considered as an indication for a physiological incompatibility between the cultivar and the rootstock.
