Comparative evaluation of Eucalyptus globulus and E. nitens wood and fibre quality

IAWA Journal, 2017
An evaluation of 100 Eucalyptus globulus and 100 E. nitens trees (six years old) was made using the Pilodyn micro-drilling tool as an indicator of wood density. Thirty E. globulus and thirty E. nitens trees with high, medium and low density were selected and sampled with an increment borer at breast height for anatomical analysis using fibre tester ...

Eliminating Growth-Stresses in Eucalyptus: A Scoping Study with E. bosistoana and E. nitens

2017
Tropical hardwoods dominate the market for fine timbers. In contrast, plantation-grown eucalypts, whether in temperate or tropical regions, are grown largely for pulpwood. Addressing log end-splitting and distortion of timber due to growth-stress is necessary if eucalypts are to succeed in solid wood markets.

Isozyme Variation in Eucalyptus nitens and E. denticulata

Australian Journal of Botany, 1998
Seed samples from 22 populations across the geographic range of E. nitens (Deane & Maiden) Maiden s. str. and E. denticulata I.O. Cook & P.Y. Ladiges wereanalysed for isozyme variation and estimation of the genetic distance betweenthe two taxa. Analysis of 12 enzyme systems in 3 buffer systems revealed 12polymorphic and 5 monomorphic loci.

Genetic parameters of intra- and inter-specific hybrids of Eucalyptus globulus and E. nitens

Tree Genetics & Genomes, 2007
Intra-specific hybrids within Eucalyptus nitens and E. globulus were compared directly with inter-specific E. nitens × globulus using common parents. Diameter (age 2, 4, 6, 10 years) and Pilodyn (age 6 years) were used as indirect measures of growth and wood density, respectively. Genetic parameters were estimated for all cross types and traits.

Novel Detection of Formylated Phloroglucinol Compounds (FPCs) in the Wound Wood of Eucalyptus globulus and E. nitens

Journal of Chemical Ecology, 2003
This study characterized the chemical responses of Eucalyptus globulus and Eucalyptus nitens to artificial inoculation with a basidiomycete decay fungus. Nine-year-old trees responded to mechanical wounding or inoculation with the decay fungus by producing new wound wood characterized by the presence of dark extractives 17 months after wounding ...

Kino vein formation inEucalyptus globulusandE. nitens

Australian Forestry, 2003
Summary Kino veins or pockets are characteristic defects of some Eucalyptus species and have long been recognised as sources of degrade in eucalypt timber. In order to investigate the causes of kino vein formation, the short-term responses of Eucalyptus globulus and E.

Daily stem growth patterns in irrigated Eucalyptus globulus and E. nitens in relation to climate

Trees, 1999
Daily increments in stem radius were determined from hourly dendrometer measurements in each of three irrigated Eucalyptus nitens and E. globulus trees. Multiple regressions determined from daily weather variables accounted for 40–50% of the variance in increment. The use of weather variables lagged by 1–2 days increased the variance explained.

Nondestructive sampling of Eucalyptus globulus and E. nitens for wood properties. I. Basic density

Wood Science and Technology, 2001
A non-destructive sampling strategy for basic density, based on removing 12 mm bark-to-bark cores, was developed in E. globulus and E. nitens. Fifty trees of each species, aged 5 to 9 years, were sampled across a range of sites. Core samples were removed on both a north-south and an east-west axis from 6 fixed heights in the base of the tree (0.5 m, 0 ...

Quantitative genetics of Eucalyptus globulus, E. nitens and their F1 hybrid

2002
This thesis examines the quantitative genetics of intra- and inter-specific hybrids of E. globulus ssp. globulus and E. nitens. The trials established to make this study are unique in forestry, due to the fact that the same parents have been used in open-pollination, intra- and inter-provenance (or intra-species) crosses and inter-species F1 hybrids ...
