Abstract
DAVIDSON, J. (1972) Variation, association and Inheritance of
morphological and wood characters In an Improvement programme for
Eucalyptus dsglupta Blume. Ph.D. Thesis, Australian National
University, Canberra, Australia. Up to 93 percent of variation In the wood of 20-year-old Eucalyptus dsglupta Bl. has been explained by four components of
a principal components analysis. Fibre cross-sectional characters
were the main parameters contributing to this variation.
Dens Ity satisfactorily represented the main and one subsidiary component
which, together, represented 70 per cent of the total variation.
Density was easy to measure and had a phenotypic variation of
about 20 per cent of the mean value.. It had a broad sense
herltabillty of 0.68 ± 0.17 and a narrow sense herltablllty of
0.44 ± 0.23 In seedling material. Density could be modified
Irrespective of growth rate and stem form In trees 14-20 years
old. Hence wood density Is a very suitable factor for Including
In a tree Improvement programme.
