Abstract

The paper focuses on the complex assessment of macrostructure indices (annual ring width, content of latewood in annual layers) and density of spruce wood in the cultures grown from the seeds of various geographical origins on the territory of the Komi Republic. Geographic races recommended for target cultivation of cultures for different purposes are selected.

Keywords

spruce, geographic cultures, climatype, annual layer width, latewood content, wood density, ranking, target cultivation.
