The objects of the study included apple trees of the following cultivars: summer cvs.: Jersymac, Discovery, Geneva Early, Close, Katia, autumn cvs.: Delikates, Lobo, Novamac, Paulared, Witos, Winter cvs.: Cox's Orange Pippin, Ligol, McIntosh, Redcroft, Sampion; late winter cvs.: Golden Delicious, Gloster, Elstar, Jonagold Rubin. All trees were planted in spring 1992 on M.26, in 3.5x1.5 m spacing. The highest content of mineral components was found in the leaves of summer cultivars while the lowest content was found in the leaves of the late winter cultivar group.
