English title: Observations on the effect of age on the basic density of larch wood

Abstract

About 100 years old larch (Larix sibirica Lebed. And L. decidua 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. The maximum basic density was reached at the age of 40–60 years, as counted from the pith. The basic density decreased as the width of the growth rings increased or the amount of heartwood decreased. The average basic density of the whole disc was 543 kg/m³ in L. sibirica and 497 kg/m³ in L. decidua. The basic densities of bark were 328 kg/m³ and 286 kg/m³, respectively.
