Biomass and growth potential of Eucalyptus regnans up to 100m tall
Forest Ecology and Management, 2015Abstract Predicting tree biomass and growth increments via allometric equations is routine in forestry, but this approach is problematic in old-growth forests unless equations are derived from trees spanning the full size range. Using intensive measurements of 27 standing Eucalyptus regnans trees 61.1–99.8 m tall and 80–430 years old in Tasmania ...

Studies of Litter in Eucalyptus regnans Forests
Australian Journal of Botany, 1975The litter of Eucalyptus regnans forests forms a mull humus, and leaf material is readily incorporated into the topsoil. The annual litter fall is high by world standards, averaging 7.66 tonneslha. The amount of bark and twig fall and the contribution of the understorey to the total litter are also com- paratively high.

Micropropagation of Juvenile Eucalyptus regnans (Mountain Ash)
Australian Journal of Botany, 1991Node-derived shoot cultures of Eucalyptus regnans were established from in vitro grown seedlings on Murashige and Skoog basal medium supplemented with 0.5 mg L-1 (2 µm) zeatin and 0.05 mg L-1 (0.3 µm) napthaleneacetic acid. A double sterilisation method was essential to obtain clean material from seed.

Water flux of Eucalyptus regnans: defying summer drought and a record heatwave in 2009
Oecologia, 2012Making predictions as to how heatwaves will affect forests in the future is a major challenge in ecosystem science, not the least because we have few documented examples of how they respond now. We captured the effects of drought and a record-breaking heatwave on whole-tree water use (Q) in Eucalyptus regnans during the summer drought of 2008/2009 in ...

An analysis of sap flow in mountain ash (Eucalyptus regnans) forests of different age
Tree Physiology, 1993Diurnal measurements of sap velocity were made in 50-, 90-, 150- and 230-year-old mountain ash (Eucalyptus regnans F. Muell.) forests in the North Maroondah catchment (southeast Australia) over the periods January 8, 1990 to April 4, 1990 and October 29, 1990 to April 16, 1991.

Bark was stripped, at monthly intervals, from the stems of ten previously-unsampled trees of Eucalyptus regnans F. Muell. The exposed surfaces of inner phloem and outer xylem yielded phloem and cambial saps which were rapidly frozen. After freeze drying to determine the contents of water and dry-matter, the samples were extracted with 80% ethanol.

THE VARIATION OF FIBRE LENGTH WITHIN ONE TREE OF EUCALYPTUS REGNANS, F.v.M.
Australian Forestry, 1949SUMMARY In an investigation of fibre lengths within one tree of Eucalyptus regnans, 50 years old and 172 feet high, particular attention was paid to the variation throughout a growth ring and it has been found that the fibres of the last-formed late wood were consistently longer than those of the early wood.

Chemical cellulose from Eucalyptus Regnans wood by autohydrolysis-explosion-extraction
Carbohydrate Polymers, 1992Eucalyptus regnans woodchips and sawdust, which were autohydrolysed at 200°C and exploded at 6·9 MPa nitrogen pressure in the Siropulper pilot plant, gave pulp yields of 68–76% with pentosan contents of 0·9–2·0%, similar to those of pulps which were not exploded.

European Journal of Forest Pathology, 1980
AbstractAn undescribed but native species of Armillaria is a secondary pathogen in declining stands of Eucalyptus obliqua and Eucalyptus regnans in southern Tasmania. The fungus is almost ubiquitous in healthy and diseased forest and occurred epiphytically or parasitically in local lesions on the roots of 74 % of eucalypts partially excavated in 15 ...
