Seed reproduction and features of formation the vegetative communities of northeast of Asia

Results of researches the reproductive features of typical kinds of vegetative communities of zonal and mountain tundras, larch forests and light forests of northeast of Asia are stated. Features of structure and biology of flower (inflorescence) are discussed, efficiency of various ways of plants pollination is estimated. Data about level of infructescence and regularity of fructification at kinds of natural and reclaiming communities are cited. The opportunity of use the resources of natural flora at creation the artificial grasslands and recultivation of derelict landscapes in specific conditions of region is considered.
