Effect of micronutrients on the biochemical composition of valerian root (Valeriana officinalis)

Abstract

on the biochemical composition of the root on the sod-podzolic sandy loam soil are presented. It is shown a weak influence on the agronomic testing the content of carbohydrates, especially soluble sugars, and a highly significant accumulation of phenolic compounds, especially leucoanthocyanins. Most effective in terms of improving the quality of medicinal raw valerian root biochemical composition proved separate use of copper and zinc micronu-trients, as well as the combined use of boron and zinc micronutrients, while the least efficient - separate use micronutrients boron and combined application of boron and copper, as well as copper and zinc micronutrients.
