Sbytna M. A genetic potential of Scots pine populations and their using for increase of capability of forest stands of Kiev Polissya

A research object is processes of growth and development of genetic refuges, highly productive planting and plus trees of pine-tree ordinary of Kyiv Polissya.A purpose is development of effective methods of the use of genetic potential of population of pine-tree of the ordinary for an increase productivity of the forests of Kyiv Polissya. Research methods: methods of forest selection - for research of the existent highly productive planting of pine-tree and possibility of increase of the productivity of the reproduced planting; forest mensuration the price - for research of growth and productivity of forest stand; comparative ecology - for determination of type of site conditions terms; agricultural chemistry - for determination of maintenance of oligoelementss in vegetable standards; mathematical statistics - for processing of experimental data.Novelty. Scientific pictures are deep of the productivity of деревостанів pine-tree of ordinary Kyiv Polissya, them plant-breeding value as genetic refuges fora maintainance and recreation of self-potential of the forest planting. Expedience and perspective of application of methods of популяційної and plus selection is confirmed at proceeding in planting of pine-tree ordinary in the region of researches. First for the south of Kyiv Polissya investigational population changeability of pine-tree of ordinary on anatomic-structural indexes pine-needles. Connection is set between morphometric descriptions of plus trees of pine-tree and their posterity and value signs. The perspective for intensive silviculture forms of pine-tree ordinary are selected. Technology of growing of plant-breeding improving planting material of pine-tree ordinary and planting created from him is improved with the use of new growth factors, microfertilizers and superabsorbents. Certainly economic efficiency of creation of forest cultures of pine-tree in Kyiv Polissya by plant-breeding-improving planting material.Research results. It is got results in relation to the selection of perspective forms of pine-tree ordinary but growings of plant-breeding-improving planting material, features of creation and growing of the highly productive planting of pine-tree are made to order for wide application in silviculture practice. They are accepted to introduction in VP Nubip "Boyarska LDS". The results of researches are also realized in methodical recommendations "Forest plantations for arboreal raw material for the necessities of cellulose and other branches of industry". Selected as a result of realization of the program of researches fast-growing forms of pine-tree ordinary "Boyarska-1" is borne in the register of sorts of plants of Ukraine.Industry is forestry.
