Variation in wood density of
Eucalyptus grandis (Hill) Maiden and E. tereticornis Sm, by A.S.
Hans, Zambia Journal of Science and Technology, Vol.1, no.4, October 1976, Pg.
Wood density of two open pollinated families of Eucalyptus grandis [Hill] Maiden
[0.426 g cm-3] and E. tereticornis Sm. [0.510 g cm-3] was determined. These were
growing in a randomized block design with three replications at Chati [Copperbelt],
Zambia. From each three four discs at 10, 30,50, and 70 per cent of tree height
were sampled. The analysis of variance revealed significant difference between
trees and between segments. The segment near the bark had higher density than
inner segments near the pith. The increase in density from pith to the bark was
approximately linear. A combination of two samples at 10 and 30 per cent height
levels was the best estimator of average value of the tree.
