This work was aimed at studying the effect of a preparation containing nanoparticles of iron oxyhydroxide on rooting and development of the root system of cuttings of the two plant species sensitive to iron deficiency: Ribes nigrum and Ribes rubrum (Grossulariaceae). Research has shown that the iron oxyhydroxide has an inhibitory effect on the growth and development of the root system of cuttings of black and red currant. When concentration increases from 0.001% to 0.1%, rooting of cuttings decreases, and the Spearman rank correlation shows strong negative dependence of the number of roots and their length on the concentration of the preparation (Rs = -0.83 -0.94...) – the number of roots on cuttings decreases, while in case of the maximum concentration, root length significantly reduces. In the studied concentration, the preparation containing iron oxyhydroxide nanoparticles cannot be used as a stimulant of root formation for rooting of cuttings of black and red currant.
