Abstract

The growth and seed production of Siberian and Korean stone pines at the age of 24–41 years in the «Izvestkovaya» plantation, located in the area of educational and experimental forest enterprise of the Siberian State Technological University (socalled Green Zone of Krasnoyarsk City) were analyzed. It has been found that Korean stone pine (Pinus koraiensis Siebold & Zucc.) is behind of Siberian stone pine (Pinus sibirica Du Tour) in growth rate, the formation of cones and microstrobiles. Inter-and intraspecific variation in the formation of tree crown, cones and seeds size were significant, which allowed selection of individual trees with better reproduction characteristics.
