Sagaydak S. Influence of origin of seed on intraspecific changeability of Scots Pine in the cultures of Kievasky Polissya

Object - intraspecific changeability of pine-tree in the ecolodgy-geographical and tester cultures of Kievsky Polissya. Purpose - exposure of the most perspective forestryseeds districts of pine-tree ordinary for the use of their seeds in the cultures of Kievsky Polissya. Methods - in the basis of theoretical researches of the given work both scientific methods (analysis, synthesis, supervision, experiment and design)and concrete (special) methods of cognition are found, that are developed for forest fixedness, forestry, physiology of plants and other forestry disciplines, the price. For the decision of special tasks specific methods were applied: morfometrich - for the study physiological of active root, methods of study poleen, seeds -study of changeability of descriptions of pollen and cones, methods of mathematical statistics - during working of finding (correlation and dispersion analyses, and others like that). Novelty -consider inadvisable climatups for the use in forest in the of Kievsky Polissya districts. For the terms of Ukraine first definite specific of accumulation of mass of the upground organs of pine-tree of and different geographical districts, the trained features of distribution districts of active roots in underground. The detailed researches of generativnih indexes of pine-tree are conducted, the trained features of gametofito and embryo seeds of rudiments in the cones of this kind depending on the geographical origin, the exposed features of biochemical composition of pollen of pine-tree, them viability and fertilnist in ecolodgy-geographical cultures in Kievsky Polissya.Results of researches - for the decision of row ecological, power, production of a particular branch questions, that need the districts of Kievsky Polissya, and in Ukraine in whole, it is recommended for the practical use: gitomirsciy and gomelsciy climatipi pine-trees of ordinary for the purveyance of seeds material with the purpose of growing of the highly production planting of pine-tree in Kievsky Polissya. Seecontinuation:Continuation 9118 "Abstract"To provide and use seeds material from the north regions of Polissya (Polisciy forestryseeds district). To consider inadvisable creation of cultures in the conditions of Kievsky Polissya to use seeds material from the Carpathians, Dnepr right-bank, Dnepr left-bank forest-steppe forestryseeds district. With the purpose of clarification of forestryseeds district of Ukraine it is suggested to exclude for Kievsky Polissya forestryseeds district of Cievsco-chernigivscogo district - East, Pridniprovskiy forestryseeds district. Field - forestry.
