Today, reforestation is becoming a priority task for Russia’s forest policy, but many issues are still poorly understood. When developing forest plantation, many factors, both biotic and abiotic, are not taken into account, which leads to the death of the developed forest stands. The results of studies of provenance trial plantations of Siberian cedar (Pinus sibirica Du Tour) and Korean cedar (Pinus koraiensis Siebold et Zucc) in Krasnoyarsk Krai and Khabarovsk Krai are reflected in a number of works (Bratilova, 2004; Iroshnikov, 1983, 2001; Kuznetsova, 1998; Romanova et al., 1996; Koryakin et al., 1999, etc.). At the same time, the problems associated with the creation, growth and development of provenance trial plantation in the Primorsky Territory remain poorly understood. The aim of the work is to identify the nature of the interdependencies of linear growth of pine stands in various environmental conditions. The indicator studied in the paper is a series of deviations and linear growth from age states (i.e. growth indices), which characterize the degree of variability during tree growth. The object of measurements was a Korean pine on the territory of the forest area of the Primorskaya State Agricultural Academy.
