Abstract.

Mineral fertilizers are one of very effective exogenous regulatory factors

able to considerably change coordination bond relations, and the speed of accumulation

and movement of transport compounds in plants. In the work the results of the research

on the effect of nitrogen (N180N270, control) dose on spruce physiology in the northern

taiga whortleberry birch forests have been given.

Keywords:

assimilates, radiochemical analysis, metabolism, nitrogen dose,

radioactivity of needles
