Micropropagation of Juvenile Eucalyptus regnans (Mountain Ash)

Australian Journal of Botany, 1991
Node-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.

End-force distributions during bending ofEucalyptus regnans

International Wood Products Journal, 2016
Variation in end-force across the thickness of Eucalyptus regnans bending specimens has been measured using a novel differential-end-force-sensor, purpose designed and built with three sensors to detect force near the surfaces and the neutral axis of the specimen. Two experiments were conducted that showed that the type of end-restraint does affect the

Succession of fungi in leaf litter of Eucalyptus regnans

Transactions of the British Mycological Society, 1966
The succession of fungi associated with the decomposing leaf litter of Eucalyptus regnans F. Muell. has been studied over a period of 60 weeks. A technique for separating the litter into layers in order to relate the degree of decomposition of the leaves to the mycofloral population is described.

Chemical cellulose from Eucalyptus Regnans wood by autohydrolysis-explosion-extraction

Carbohydrate Polymers, 1992
Eucalyptus 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.

BREEDING EUCALYPTUS REGNANS—FIVE YEAR PROGRESS REPORT

Australian Forestry, 1964
SUMMARY The breeding programme at Traralgon aims to improve Eucalyptus regnans F. v. M. as a forest tree by increasing the rate of growth, improving wood quality, and increasing resistance to damage by fire. Improvement may be accomplished in three ways:—(1) provenance trials (to determine the best place to collect seed for afforestation in a given ...

Moth pocket, a timber defect inEucalyptus regnans

Australian Forestry, 1983
It is proposed that “bird's eye”, a common timber defect of Eucalyptus regnans, be renamed “moth pocket” because of its origin and appearance.

EMERGENCE OF EUCALYPTUS REGNANS SEEDLINGS FROM BURIED SEED

Australian Forestry, 1965
SUMMARY Seed of Eucalyptus regnans F. Muell. was sown at various depths in crumby and in highly compacted soils. The numbers of seedlings which emerged per cent of sound seeds sown in crumby soil were: on the surface—16%; at 1/4 inch depth—51%; at 1/2 inch—18%; at 1 inch—2%; and at 2 and 4 inches—0%.

Studies of Litter in Eucalyptus regnans Forests

Australian Journal of Botany, 1975
The 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.

EFFECTS OF FIRE ON SEEDSHED FROM EUCALYPTUS REGNANS

Australian Forestry, 1965
SUMMARY Patterns of seedshed were studied in several burnt and unburnt stands of Eucalyptus regnans F. Muell. in central Tasmania by catching the seed in traps and examining the capsules on the trees. Timing of the seedshed is important because the bulk of the natural regeneration must normally come from the seed which is shed within one year after ...
