Silver Nanobiocomposites Based on Humic Substances As Highly Efficient Stimulators of Seed Germination

Abstract

Silver-containing nanocomposites are synthesized from humic peloid substances in an environmentally friendly way. The growth-stimulating activity of ultralow concentrations of humic substances of therapeutic muds and silver-containing compounds on their basis is studied. The stimulator active concentration range upon wheat seed generation is determined to be 4 × 10^–3–4 × 10^–16%. The fastest (almost double) growth of the main roots of sprouts is found to be for silver nanocomposites based on humic substances. The established activity of nanocomposites is a prerequisite for the development of novel highly efficient growth-stimulating drugs.
