Weather conditions favouring cone initiation for Siberian stone pine (Pinus sibirica Du Tour)

open access: yesFORESTRY BULLETIN, 2023
Seed production in 25 trees of Siberian stone pine (age 180-200 years) over a 28-year period was examined to determine how the weather factors and their period influence strobilus initiation. Since floral induction in Siberian stone pine occurs in a short period of time only during three weeks at the end of summer, the dynamics of temperature and ...
