Abstract
The research was conducted on the LEP-2 plantation located in the Karaulnoye forestry of the Educational and Experimental Forestry Enterprise of the Siberian State University of Science and Technology named after M. F. Reshetnev. The second generation of Pinus Sibirica of different geographical origins: Altai (Atushken, Kurli, Tushtuezhen tracts), Biryusinsky, Tanzybeysky, Tisulsky, Cheremkhovsky, Yartsevsky grows on this plantation. The plantation was created from seeds collected on the Meteostation and Izvestkovaya geographical plantations located in the same forestry. According to the intensity of growth on the plantation “LEP-2” there are specimens that exceed the average value by origin in height and trunk diameter by more than 15 %: No. 6-3, 6-18, 6-38, 6-43, 6-46, 3-43,3-47 of Altai origin; No. 2-30, 2-36 and 5-8 of Biryusinsky origin; No. 3-10, 3-11, 3-13, 3-15, 8-43 of Tisulsky origin and No. 4-9, 4-12, 4-15, 9-6 of Yartsevsky origin on the plantation “Meteostation”: and No. 4-30, 4-37, 4-40 of Tanzybei origin and No. 2-12, 2-14, 2-15, 2-17, 8-2 of Cheremkhovsky origin on the Izvestkovaya plantation. According to early reproductive development with the formation of macrostrobiles, 6 trees stand out. The largest number of macrostrobiles was in specimens No. 5-12 of Biryusinsky (4 pcs.) and № 8-37 of Tisulsky (3 pcs) origin. Microstrobiles were formed in 12 trees. The highest value was in specimen No. 4-21 of Yartsevsky and No. 6-7 of Altai (ur. Atushken) origin. Two specimens that formed macro- and microstrobiles were selected: No. 3-32 of Tisulsky and № 5-12 of Biryusinsky origin, and two specimens are both fast-growing and early in pollen formation: No. 3-13 of Tisulsky and No. 6-46 of Altai (ur. Kurli) origin. Selected specimens are supposed to be propagated vegetatively in order to grow planting material characterized by intensive growth and early reproductive development.
