Raw materials of <i>Hypericum perforatum</i> L. of different geographical origin in the conditions of introduction

Abstract

The results of studying the growth, development and formation of the raw phytomass of Hypericum perforatum plants of different geographic origin during the introduction in the middle taiga subzone of the Komi Republic are presented. Seven samples of Hypericum perforatum were examined, including two cultivars: Zolotodolinsky and Solnechny. A sample (Tallinn No. 885) was identified, which differed in earlier dates of the onset of phenological phases. Hypericum perforatum plants under culture conditions in the middle taiga subzone of the Komi Republic are characterized by a stable developmental rhythm. It has been determined that the number of generative shoots in Hypericum perforatum increases with age. So, in two-year-old plants this indicator was 3-4, in four-year-old plants - 18-26 pcs. per individual. It has been established that from the second year of life, with the seedling method of growing, Hypericum perforatum plants are able to form high yields of medicinal raw materials. As a result of an assessment of the productivity of samples of cultivar Solnechny and sample from Barnaul.
