BIOACTIVITY OF SYNTHETIC HUMIC-LIKE SUBSTANCES ON EARLY STAGES PLANT GROWTH

Abstract

Biostimulating properties of humic acids and humic-like substances are of significant interest in the field of plant biochemistry, while the nature of their actions at various levels of the substance organization is not sufficiently studied. The use of natural humates as growth regulators is associated with a number of limitations, in particular, their preservation of natural genesis, low solubility in water, a narrow range of active concentrations, insufficient biological activity [1], as well as the labour intensity of substances isolation from natural raw materials, which suggests the relevance of the development of synthetic growth regulating compositions, including based on products of sugar-amine reactions [2].
