Observations on the effect of age on the basic density of larch wood

Silva Fennica, 1978
About 100 years old larch ( Lebed. And Mill.) trees were felled and the basic density samples taken from the stump level were determined. The number of trees was 21 and number of samples 378.

Calculating the basic density of whole tree- and logging residue chips

Silva Fennica, 1977
A method is presented in this study for calculating the basic density of whole tree- and logging residue chips and the results of trial measurements on some commonly used chip sorts. The basic density of Scots pine whole tree chips was found to be 1–18

BASIC DENSITY AND RETRACTIBILITY OF WOOD CLONES OF THREE Eucalyptus SPECIES

Ciência Florestal, 2010
Among the planted forests that supply the national wood industry, the genus Eucalyptus has become the most important, due to its fast growth, ease of large scale planting and variability of wood use.
