Abstract

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.
