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 ...

Studies on the Mycorrhizae of Eucalyptus regnans F.muell

Australian Journal of Botany, 1976
Eucalyptus regnans mycorrhizae vary from simple to coralloid forms, and their surfaces are commonly smooth or conspicuously enmeshed with external mycelium. At least 18 different basidiomycetes may be intimately associated with dense weft-type mycorrhizae; six agarics have been induced to form simple or diffuse mycorrhizae under sterile conditions ...

Collapse and internal checking in the latewood of Eucalyptus regnans F.Muell

Wood Science and Technology, 1996
Tangential shrinkage was measured on longitudinal-tangential slices of separate earlywood and latewood from one board of Eucalyptus regnans F.Muell. at various temperatures. Large amounts of collapse shrinkage were measured in the latewood slices, and lesser amounts in the earlywood slices.

Studies on the Lignin of Eucalyptus regnans I. Thiolignin

Australian Journal of Scientific Research Series A: Physical Sciences, 1948
By 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.

Preferential Outcrossing in Eucalyptus regnans F. Muell

Australian Journal of Botany, 1987
Seed production characteristics of Eucalyptus regnans following self (S), outcross (O), (S+O ) and open pollination were investigated as a contribution to understanding of breeding system control in this species. All five trees tested produced seed after self-pollination, although yield was reduced relative to outcrossing.

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.

Studies on problems of regeneration of Eucalyptus regnans in Tasmania

1966
E. regnans is confined to Tasmania and Victoria. It is one of the three or four most important timber species in these two states. In 1958, E. regnans produced the fifth largest volume of sawn eucalypt timber in Australia (Hanson, 1961). E. regnans grows best under fairly cool conditions at 100 ft. to 2,000 ft. in Tasmania and at 600 ft.

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%.

Soluble Components of the Cambial Zone of Eucalyptus regnans F. Muell.

Nature, 1963
SEVERAL investigators have shown that the nutrient fluids in the phloem and, in some instances, the liquors in the cambium of arborescent gymnosperms and angiosperms contain some of the following constituents1: mono-saccharides, chiefly glucose and fructose with traces of pentoses (mainly xylose); uronic acids, sorbitol and mannitol; disaccharides ...
