The article presents the results of the study of the influence of copper heavy metals on the germination and growth of wheat seeds (Triticum aestirum L.) of the variety Akmola 2. The study was conducted under laboratory conditions. As a source of copper, concentrations of the CuSO4 salt of 50 μmol, 100 μmol, 150 μmol, and 300 μmol were taken. The seeds were pre-primed in a solution of molybdate (75 mM Na2MoO4*2H2O) for uniform germination. The results of the influence of primed and non-primed seeds on some physiological indicators of growth and development in these concentrations of copper are discussed. The germination rate of seeds primed for heavy metal salts remains higher than that of seeds not primed. It is shown that in response to stress caused by copper metal salts, plants are responsible for the accumulation of a significant amount of proline in the leaves and roots that perform a protective function. The results obtained indicate the resistance of the wheat plant to the effects of heavy metals of copper, seeds primed with molybdate.
