The article presents the results of the influence of three growth stimulants («Gumat +7», «Bajkal» i «Zircon») on seeds of pine ordinary 6 origin with various selection category, harvested in Akmola and North Kazakhstan region. The experiment was conducted in open ground. As a result of data analysis, it was found that in most experimental variants, field germination was greater when seeds were soaked in «Zircon». As a result of autumn registration of 1-year-old pine seedlings, it was revealed that, despite a decrease or increase in the number of seedlings during the field season the high occurrence in the reference segment was in seeds of selectionvaluable and quality grade 1. The highest height of the seedlings was in the seedlings of origin from the clonе archive of the FSR «RLSSC» using «Zircon» - 5,91 ± 0,25 cm. The excess in height over control was also established in other versions of the
experiment using «Zircon» and «Gumat +7». The most homogeneous indicators of height (average height: 4,71 ± 0,22 cm, CV = 26,80%) in the control of the seedlings were of origin from the clonе archive of the FSR «RLSSC». Analysis of variance confirms that to the height of seedlings of control options influenced by the category of seeds.
