BidensradiataThuill.has a wider distribution in comparison with the succession of needles herbs (Bidens tripartite L.), which is included in the national Pharmacopoeia as medical means, and is interesting as an additional raw materials for use in medicine. Productivity is determined by the character of habitats, limiting sizes of plants and projective cover of this square view thickets (r=0,74, Rxy=0,46). The highest yield is marked on wet soils of light mechanical composition. The degree of influence of factors of vegetation (r|2x=0.68; Fфакт.=35.06). Arrays production values on all surveyed areas constitute only31 ha. Calculated biological stock is 8.91 t., production - 8.37 tons. Raw material resources sufficient for the conduct in Eastern Transbaikalia blanks in the volume of 7.52 tons annually.
