Basic Density in Norway Spruce. Part I. A Literature Review

Håkan Lindström

Abstract


The literature review establishes the background for a series of papers relating environmental influence to basic density of Norway spruce (Picea abies). The four independent theories of wood formation given indicate that crown development acts as a primary regulator of wood structure and basic density in conifers. The review focuses on variables connected to crown development and basic density. Models of basic density in Picea abies were based on variables dependent on crown development, such as stem taper and growth ring width. It is suggested that models accurately predicting basic density should be based on a set of variables closely related to crown development.
