Abstract

The paper studies the influence of drainage on the content of physiologically important elements in pine needles. The data are provided on the changes in the total content of mineral elements in pine needles depending on the crown part, as well as in needles of various ages depending on the effect produced by the drainage channel, and changes in each element content separately. The correlation analysis of the data obtained confirms that this correlation is close. Distribution of all mineral elements, the content of which was determined in pine needles, is presented in decreasing order. Elements accumulating in needles with age are noted.

Keywords

assimilation apparatus, mineral elements, drainage, crown part, age of needles, moistening conditions, interchannel space.
