Variability of scots pine in the southern part of the boreal zone of Yenisei Siberia

The article presents the results of the ecological and geographical intraspecific variability of the characteristics and properties of the Scots pine, which is hereditary. The variability of breeding characteristics of populations of Scots pine growing in the ecological and geographical conditions of the forest-steppe zone of the Krasnoyarsk Territory on the territory of the experimental base “Pogorelsky Bor” is considered. 

The research area is located on the territory of the Krasnoyarsk forest-steppe and is an “island” of pine forests of cranberry-green and mixed-grass groups of forest types of II–III classes of bonit. 

The color of the cones showed a low diversity in color with slightly different shades: gray – green (35.5 %), gray (55 %), beige (8.3 %), gray-greenish with tan (1.7 %). According to the color of the seeds, the category of dark–colored seeds is mainly represented (72.5 %): dark brown (3.4 %), dark gray (24.2 %), dark brown (3.4 %), black (41.5 %) shades. The category of light-colored seeds is only 27.5 %. Seed quality indicators depend on morphological and phenological polymorphism. The analysis of the taxation indicators indicates a good linear growth of the Scots pine (the average height was 28.6 m, and the average diameter was 32.4 cm High rates of linear and radial growth indicate better productivity and, accordingly, good growing conditions for stands of Scots pine in the Pogorelsky forest.
