MORPHOGENETICAL AND BIOCHEMICAL REGULARITIES IN GROWTH AND DEVELOPMENT OF TRACHEIDS AT FORMATION OF XYLEM IN CONIFEROUS TREES

The work covers the Siberian larch and Scotch pine growing in the equal and different ecological conditions of the Krasnoyarsk territory. The aim is to study the regularities connected with formation, growth and development of the conifer cells, intercommunication of the morphogenesis with special biochemical features of forming structure of the tracheid walls and influence of the external factors on the morphogenesis stages. The morphogenetical and ecological causes of the differences in the tracheid sizes, wood quality and productivity of the studied types have been revealed. The original hypotheses of the biochemical events explaining these differences have been proposed. The determined regularities of the tracheid morphogenesis and influence of the external factors on each stage of the cytogenesis give a theoretical base for development of the methods acting on the wood quality and prognosis of developing the annual layer of wood according to the climatological season situations and dendrochronological analysisAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
