DEFINITION OF FACTORS OF DETERMINING RATE OF SEED HARVEST OF COMMON PINE

As real sources of seeds, there are different seed plants and wood walls. However, influence of walls of the wood is limited to a strip in 40-50M width in connection with features of a rating of seeds. The spew of seeds, certainly, is car-ried out on the large square, but possibilities of seed sprouting and preservation of seedlings of a pine were available only in a zone of protective influence of trees, which in this case was measured in 25-35 m. Here already the confined-ness of young growth to a shadow cone affects the characteristic for ribbon forests of Priirtyshje.
