Abstract: In this research carried out in the greenhouse of Uludag University, Mustafakemalpaşa Vocational School, the initial development of 11 lines (CMS01, CMS10, CMS23, RHA03, RHA10, CMS01 x RHA03, CMS01 x RHA10, CMS10 x RHA03, CMS10 x RHA10, CMS23 x RHA03 and CMS23 x RHA10) and two varieties (MAY AGRO and SANAY) of sunflower, with four different doses of salt (0, 4, 8 and 12 dSm-1) was examined. Ion analysis was done at the Faculty of Agriculture, Department of Soil Laboratory. The roots and leaves of the plants were analyzed for variation with respect to salt dosage in terms of the concentrations of Ca, Na and K and the ratios of Ca/Na and K/Na. According to our research results, Ca, K, Ca/Na and K/Na ratios as opposed to the increase of salt dose reduced, but Na ratios increased. Ca and K in the leaves and Na accumulated in the roots. The minimum and maximum average values of Ca in roots (2.02-3.46%) and leaves (1.87-3.41%); of K in roots (1.91-3.33%) and leaves (3.34-3.97%); values of Na in roots (2.48-5.67%) and leaves (1.63-3.09%) all changed. The CMS01 line had the highest concentrations of Ca and K, while the CMS23 line had the highest tissue concentration of Na.
