The distribution of the trace elements (Fe, Ni, Mn, Cu and Zn) in aerial organs of grapevine plants under the influence of foliar treatment with iron and nickel-containing compounds was studied. It was found that foliar treatment affected not only the content of the introduced elements but some other ones too. Exogenic Fe accelerated the efflux of trace elements from leaves to annual an perennial shoots and Mn accumulation in the leaves. The Cu content decreased in leaves and increased in shoots. The tendency to the decrease of trace elements content in generative organs of the plants after treatment was observed, especially in berries. High content of Ni in generative organs in comparison with the vegetative ones was established.
