Weather Conditionality of Siberian Stone Pine (Pinus sibirica Du Tour) Seeding

open access: yesLesnoy Zhurnal (Forestry Journal), 2021
The dynamics of Siberian stone pine sexual reproduction in the South-Eastern part of the West Siberian Plain was studied by 13-year stationary observations. The stand age was 160–180 years, the average tree height was 22 m, and the average diameter of the trunk at breast height was 53 cm.
