Abstract: Mast seeding is one of the most peculiar reproductive behaviors observed in trees with high interannual variation at the population level following irregular intervals. Mast seeding has several demonstrated fitness benefits, including adjusting the predator population, enhancing pollination rate, increasing attraction of seed dispersers and reducing the impact of seed predators. It is an evolutionary strategy beneficial for the reproductive success of a population, but disadvantageous to high and stable yield in seed and fruit production. This paper reviewed the characteristics of mast seeding and its effects on vegetative growth and resource consumption of trees, and analyzed the main factors impacting mast seeding, including carbohydrates, mineral nutrients, hormone levels, and climate factors. Finally, the research directions for mast seeding in forest trees in China were proposed.
