The use of biogenic ferrihydrite nanoparticles in the reproduction of Ribes nigrum L. lignified cuttings

Abstract

The paper presents the results of the use of black currant (Ribes nigrum L.) variety Sofya with lignified cuttings of solutions of nanoparticles of biogenic ferrihydrite in two modifications. Colloidal nanoparticles of “pure” ferrihydrite (Feh) and ferrihydrite doped with aluminum (Feh_Al) have been tested. The research results showed that soaking the cuttings in solutions of nanoparticles and exogenous treatment with these solutions can increase the rooting rate of cuttings of black currant. The maximum rhizogenic activity of cuttings was noted in the variant with ferrihydrite doped with aluminum - 61.9%, which was statistically confirmed. In the variant with Feh, rooting was lower in comparison with the control by 28.1% and with the variant Feh_Al by 4.9% and amounted to 57%.
