Contact dermatitis from radiata pine
Contact Dermatitis, 1976Sawdust from radiata pine trees which are grown extensively throughout South Australia causes various forms of contact dermatitis. The various forms are described in nine cases which illustrate that the early diagnosis of industrial dermatitis is necessary to prevent the condition from becoming chronic. A chance association between colophony in radiata

Prospects for clonal forestry with radiata pine
Australian Forestry, 1984Summary The advantages of vegetative propagation of forest trees are discussed. The history of the development of such techniques with radiata pine (Pinus radiata) is outlined and a new technique for mass propagation of cuttings of the species described. It is suggested large scale clonal plantations of this species are now possible.

Stiffness gradients in radiata pine trees
Wood Science and Technology, 2004A mill study of 62 trees, in which boards were reassembled into their original logs, permitted the construction of wood quality maps. In this instance stiffness profiles were obtained from butt to upper-top logs, based on machine stress grading of all boards and then averaging values from the 62 trees.

Optimizing radiata pine drying schedules
Wood Material Science & Engineering, 2011Abstract In an era of increased energy costs and concern about profitability, using the best drying schedule is important for softwood drying. The first part of this study looked at the feasibility of finding the combination of dry bulb, wet bulb and air velocity that either minimizes overall drying cost or maximizes profit in a simple radiata pine ...

Australian Forestry, 1974
SUMMARY The short-term effects on basal area increment, volume increment, and stem form of pruning radiata pine (Pinus radiata D. Don) to 2.3 m four, five and six years after planting at Brunswick, Western Australia, are compared with the growth of unpruned trees, and the relevance of these effects to pruning policy are discussed.

Cold Hardiness of Radiata Pine (Pinus radiata D. Don)
2001Pinus radiata D. Don is native to North America, with three mainland populations on the coast of central California and two island populations off the coast of Baja California, Mexico (Scott 1960). The species occupies only about 7,000 ha in its natural habitat and is of little commercial significance (Burdon and Miller 1992), except to the Christmas ...

Experimental Prescribed Burn In Radiata Pine
Australian Forestry, 1968SUMMARY A prescribed burn of low intensity was carried out in a 23-year-old plantation of radiata pine (Pinus radiata D. Don). The burn reduced the fine fuel from 3.6 to 2.6 tons per acre, and it was a satisfactory hazard-reduction measure. Infiltration rates were determined before and after the fire by applying artificial rainfall, at the rate of 80 ...

Dielectric properties of radiata pine
2000The dielectric properties (< 1 MHz) of radiata pine were studied as a function of moisture content to determine if any potential existed for moisture measurement above the fibre saturation point (approximately 35 % moisture). An edge capacitance correction and a method of estimating the conductivity contribution to the dielectric loss were employed.

The colour of the wood in radiata pine has large variations due to natural factors and also wood processing treatments. Wood colour has been previously studied in many wood-related processing areas, such as pulp and paper, coating, photoyellowing and veneering, while few studies have been done on the colour of fresh, green wood.

Commercial micropropagation of radiata pine
1993The incentive for Tasman Forestry Ltd. (T.F.L.) entering a programme of clonal forestry is the prospect that some clones will produce a large increase in value over unimproved stock. Some of the most genetically advanced control pollinated families are anticipated to yield an approximate 20% increase, over unimproved seed.
