Spring wheat variety Vanek was cultivated on 10 square m trial field plots on brown loamy soil during 2005-2007. Plants were treated with eight different types of brassinosteroids (24-epibrassinolide; 24-epicastasterone; compound 4154 and five androstane and pregnane analogues) at growth phase 49-59 DC (from visible awns to complete inflorescence emergence). The content of metals (Ca, Cu, Fe, K, Mg, Mn and Zn), yield and quality parameters of wheat grain were determined. Our three-year results showed that after the BRs treatment of spring wheat some changes of the metals content were determined. However, these changes differed among the experimental years. Grain quality, grain yield per hectare and TGW were not affected by the treatment with brassinosteroids in the investigated years.
