This research was carried out during the 2006-2007 growing season in the field under rainfed conditions. The aim of the study was to determine the growth stage effect on distribution and accumulation of mineral elements in three wheat varieties [V1: Yuna (60690), V2: Dahe (61978) and V3: Sfera (61979)]. Wheat plants were sampled in the field during heading, soft dough, hard dough stage, and harvest time. Sample were collected from stem, old leaves, flag leaf and spike. Quntative analysis of mineral elements were determined by polarized energy dispersive x-ray fluorescence (PEDXRF). According to obtained results phosphorus (P), magnesium (Mg), calcium (Ca), sulfur (S), manganese (Mn), copper (Cu), silicon (Si) and nickel (Ni), strontium (Sr), and barium (Ba) were accumulated in the flag leaf while potassium (K), sodium (Na), chloride (Cl), iron (Fe), and bromine (Br) remained in te old leaves. The higher concentiration of zinc (Zn) was in the spike. Rubidium (Rb) and cerium (Ce) were nearly distributed on the all plant parts. In general concentirations of mineral elements were increased from heading to harvest time. Wheat varieties had different respond to mineral elements distribution and accumulation.
