In this paper, we describe development of Picea ajanensis (Lindl. et Gord.) Fisch. ex carr. plants during virginal stage, as one of the main edificators of Korean pine-broadleaf forests of the southern part of the Russian Far East. The study was conducted on the territory of the Verhneussurijsky Research Station of the Institute of Biology & Soil Science FEB RAS. The Station is located on the eastern macroslope of the southern part of the Sikhote-Alin mountain range. Using dendroecological approach, we have restored history of development of virginal P. ajanensis plants. We found the periods when there is an agreed (because of severe disturbances of the stand canopy) increase of the radial growth of most plants, in particular, taken place in decades of 1880–1889, 1920–1929 and 1960–1969. Such severe disturbances contribute to the formation of new generations in which plants have the same age stage, but differ in absolute age. We have identified the moments of transition from one phase in age stage to another. It is found that despite of the presence of acceleration and deceleration periods of growth, height and diameter growth rates are relatively evenly. Also thinning process does not stops with the transition of trees from virginal age stage and continue in the generative stage.
