OPTIMIZATION OF TECHNOLOGY OF GROWING OF NORWAY MAPLE SEEDLINGS ON THE BASES OF ORGANOGENESIS PHASES

Taran S.S, Kolganova I.S
For most of ornamental trees and scrubs the most studied development phases are embrio, virginil and generative. However, researches avoid detailed studying of plant growth and development during juvenile phase, recognizing importance of active intervention in this period. It is defined that during juvenile phase of development of Norway maple seedlings there is definite periodicity of woody plant growth, called organogenesis phases, according to which carried out land treatment measures have maximum effect. Basing on the analysis of changing of linear sizes of seedlings and mass of dry organic matter the following growth phases are determined: seed-lobe, kaf and root. When passing them, the need of plants in water and food elements changes. During seed-partial phase seedlings require a number of main abiotic factors of environment as warmth, access of air and light. Requirement in much quantity of water and minerals arises during leaf phase. The need in water and nitrogen retains during the first part of root phase, but other macro elements are also wanted. Then redistribution of stored organic matter in over ground part takes place, and ash substances consumption decreases. A number of internodes is taken as a diagnostic feature of phase coming because it does not depend on the date and weather conditions of definite calendar year.
