Estimativa da produção de madeira e da casca de clones de eucalyptus através da densidade básica

Abstract

The basic density of wood is an important physical property that together with the dry weight are used to determine the production and / or productivity of a forest stand. With this, the objective of this work is to estimate the production in dry weight of wood and bark of Eucalyptus genetic material. For this, nine genetic materials were used with three trees of each genetic material, totaling 27 trees. The trees were cubed to determine the volume and percentage of bark. The trees were sampled by removing five disks each for determination of the basic density and dry weight of the samples. The estimated wood production of the genetic material was: 1 – 139,11 ton/ha; 2 – 33,71 ton/ha; 3 – 138,00 ton/ha; 4 - 139,11 ton/ha; 5 – 51,00 ton/ha; 6 – 190,44 ton/ha; 7 – 44,44 ton/ha; 8 – 141,55 ton/ha; 9 – 31,88 ton/ha. The peel production estimate of the genetic material was: 1 – 14,66 ton/ha; 2 – 33,71 ton/ha; 3 – 18,22 ton/ha; 4 – 18,77 ton/ha; 5 – 12,14 ton/ha; 6 – 30,77 ton/ha; 7 – 7,55 ton/ha; 8 – 22,00 ton/ha; 9 – 7,00 ton/ha.
