The results of an analytical review and evaluation of long-term experimental data on the dynamics of seed-bearing of Siberian pine in the Novosibirsk region at the objects of the forest seed base in the Iskitim forestry are presented. The analysis of the development of the generative part of the cedar depending on the hydrothermal conditions of the years of study and the individual variability of clones. The data obtained indicate that the growing conditions and humidity, as well as the temperature factor affect the periodicity of seed production. The years that differ in the volume of cedar seed harvesting for the period 2009–2017 are highlighted. Years of mass harvests and crop failures need to be investigated to study the causes of periodicity of fruiting and features of the process of pollination, fertilization and development of cones.
