Studies on the Lignin of Eucalyptus regnans I. Thiolignin
Australian Journal of Scientific Research Series A: Physical Sciences, 1948By pulping Eucalyptus regnans by the kraft process, acidifying the black liquor, and fractionating the product, a thiolignin has been prepared in a pure state. Thiolignin reacts with diazomethane to yield a trimethyl derivative, and with dimethyl sulphate to yield a hexamethyl derivative.

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.

Tableros OSB fabricados con madera de Eucalyptus regnans
2009El informe evalua alternativas de aplicación industrial para la madera de Eucalyptus regnans, con el objeto de fabricar a escala industrial un tablero OSB de 11,1 milímetros de espesor y determinar sus propiedades físicas y mecánicas. También se pretende comparar las propiedades de los tableros OSB fabricados con madera de Eucalyptus regnans y los ...

Change in yield of water following a bushfire in a forest of eucalyptus regnans
Journal of Hydrology, 1976Abstract The hydrological changes following regeneration by fire of forests of Eucalyptus regnans were analysed in detail using non-parametric statistical methods. The streamflow data showed that some three to five years after the fire the flows started declining below the levels prevailing before the fire. The average annual reduction in flow over

The Seasonal Growth of Eucalyptus regnans F. Muell
Australian Journal of Botany, 1975At Wallaby Creek, Vic. (altitude 670 m), Eucalyptus regnans seedlings 1-6 m in height usually commence growth in early September, reach maximum growth in midsummer and cease growing in late May. The active growing season when shoot growth exceeds 12 mm per month is 7-9½. months.

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 ...
