Research results on the effect of Amur larch (Larix amurensis B. Kolesn.) seeds treatment by different concentrations of growth stimulators Appin-Extra and Zircon on germinative energy and laboratory germination are presented. The most stimulating effect when Amur larch seeds sprouting shows Appin-Extra with solution concentrations 1x10-3-1x2x10-3ml/l. Higher (0,5x10 ) and lower solution concentrations (1x4x10-3-1x5x10-3 ml/l) produce an inhibitory influence on germinating capacity and laboratory germination of seeds. The efficiency of growth stimulator Zircon is observed by weaker solution concentrations (1x2x10-3 -1x4x10-3ml/l).
