Comparison of Genetic Parameters for Wood Properties Expressed on Volumetric and Gravimetric Bases

Estimates of genetic parameters for wood properties and their interpretations can vary substantially depending on the units in which the wood properties are expressed. Of particular concern in this respect are estimates of genetic variances for moisture content, extractives yield and pulp yield when these traits are expressed on a gravimetric (dry weight) rather than volumetric basis. Corresponding estimates of genetic correlations of these variables with density depend strongly on the unit basis used. Arguments favoring the use of the volumetric basis for expression of certain wood properties are strengthened by comparing results of genetic analyses of traits expressed on the gravimetric versus volumetric bases.
