Abstract :Romania has very good walnut insert ignore into journalissuearticles values(Juglans regia L.); cultivars. In this study nuts of different walnut cultivars insert ignore into journalissuearticles values(‘Valcor’, ‘Valmit’ and ‘Valrex’); grown in Romania were evaluated for their physical characteristics and mineral composition. Walnut samples were collected during the years 2008 and 2009. Microelements Na, Ca, Mg, Fe, Mn, Cu, Se, Al, Cr, Zn, Sr and Rb were determined by using ICP-MS as measurement tool, while K content was determined with an atomic absorption spectrometer in flame, by using as excitation source the cavitar cathode lamp for potassium. Mineral con-tents insert ignore into journalissuearticles values(mg/100 g); were: K, 387.25-444.35; Mg, 264.7-272.3; Ca, 62.78-72.91; Mn,10.45-18.06; Fe, 5.44-5.90; Zn, 3.19-4.10; Cu, 2.93-3.47. Physical characteristics of fruits represent a quality feature of nuts; they varied within small limits insert ignore into journalissuearticles values(56.54-59.64% kernel percentage, 14.0-16.65 g fruit weight, 7.80 – 9.92 g kernel weight, 33.3 - 38.15 mm fruit diame-ter, 38.2 – 42.2 mm fruit height);. Fruit properties indicate that ‘Valcor’, ‘Valmit’ and ‘Valrex’ are superior walnut cultivars in terms of physical properties and mineral composition.
