The article presents the results of studying the effectiveness of growth stimulators (regulators): heteroauxin, kornevin, zircon on rooting of juniper genus (Juniperus L.) annual cuttings at the nursery of the Partizansky forest district of the Sergeevsky branch of KGKU "Primorsky forest district". Heteroauxin had the most effective impact on the growth of the cuttings root system, in which the length of root lobe exceeded the control group on average: in Sargent juniper (Juniperus sargenti i (A. Henry) Takeda ex Koidz.) by 13,3-81,3 %, in Dahurian juniper (Juniperus davurica Pall.) by 41,9-54,7 %, and in needle juniper (Juniperus rigida Siebold et Zucc.) by 51,9- 85,7 %. When the cuttings were processed with a growth stimulator zircon,the exceeding to the control group comprised respectively: 26,7-30,7; 4,3-5,1 and 20,8-32,5 %, and with the growth stimulator kornevin - by 36,0-44,0; 11,1-51,3 and 1,3-54,5 %. Similar dependence was found with the use of these growth stimulators and methods for their use.
