The infuence of the growth stimulator of natural origin Ecopin on the sowing qualities of seeds of coniferous tree species - Scots pine (Pinus silvestris L.), which grows in the forest conditions of the southern part of the Far East, is studied. The use of the biological product activates the germination energy and laboratory germination at concentrations of solutions 1×2×10-3 - 1×5×10-3 ml/l within 71.3 -79.9 % and 83.7-96.4 %, exceeding control, respectively by 5.2- 17.8 % and 6.9-23.1 % and, as a result - increasing sowing qualities of seeds on one-two classes: from the third - to the second and the frst. The concentration of 1×6×10-3 ml/l had an insignifcant effect on the sowing quality of seeds (exceeding the control of 0.6-2.4 %). With the weakening of the concentration of the solution to 1×7×10-3 ml/l, the germination energy and germination of seeds decreased, relative to the control, by 11.4-13.0 %. A higher concentration of the solution (1×10-3 ml/l) had an inhibitory effect on seed germination. The concentration of solutions 1×3×10-3 - 1×4×10-3 ml/l (exceeding the control of 22.2-46.7 %) had the greatest effect on the growth of seedlings along the length. In comparison with the control, the concentration of 1×10-3 ml/l reduced the growth rate of seedlings by 5.9- 11.1 %. Further reduction of the solution concentration to 1×7×10-3 ml/l was ineffective. Ecopin also had a positive effect on the formation of the mass of sprouts. At concentrations 1×3×10-3 - 1×5×10-3 ml/l, the excess to the control was -19.8-59.4 %.
