| dc.description.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. | en_US |
