  • Siberian stone pine (Pinus sibirica Du Tour) is a cone-bearing species with outstanding nutritious seeds, health-supporting properties, and nut oil. Currently, the main volume of pine nuts is harvested in natural forests, which causes damage to ecosystems. The best solution to this problem would be harvesting nuts on special pine nut plantations established on the basis of high-seeding clones. However, it is hampered by the low efficiency of the existing methods for assessing plus-tree productivity.
