abstract: Winter rye (Secale cereale L) variety Rostockie was studied. Using AAS Perkin Elmer 3300 apparatus, the amounts of copper, zinc and calcium in the roots and upper parts of rye plants were investigated. The plants grew in a nutrient solution at pH 7, and after reaching the shooting stage the pH of the solution was adjusted to pH = 4.5 and various zinc (ZnCl2) amounts (Zn 20, 200, 400 mg dm-3) and copper (CuSO4•5H2O) amounts (Cu 20, 50, 100 mg dm-3) were added. The content of copper and zinc ions increased in rye roots and upper parts. At higher concentrations of copper and zinc, content of calcium ions in the roots decreased. On the other hand, calcium ions content decreased in the upper parts during the zinc stress. Influence of higher copper concentrations on calcium ions concentration in the upper parts was not significant. Zinc ions concentrations of in the roots and upper parts of rye under copper stress conditions decreased.
