Carbohydrate Metabolism in the Sapwood of Pinus radiata
Nature, 1963THE use of carbon-14 produced in nuclear bomb testing in biological investigation has been discussed in an earlier communication1. Since 1954 the specific activity of the carbon dioxide in the atmosphere over New Zealand has been increasing, as is shown in Fig. 1 2. We have used this effect to examine the carbohydrate metabolism of Pinus radiata.

A xyloglucan in etiolated seedlings of Pinus radiata
Phytochemistry, 1997Abstract The changes in cell wall carbohydrates and starch were investigated in hypocotyls and cotyledons during growth of etiolated seedlings of Pinus radiata. Starch was depleted within two weeks with an accompanying rise in a hemicellulosic xyloglucan component. This was purified by fractional precipitation.

Resin Metabolism in the Sapwood of Pinus radiata
Nature, 1963Carbon-14 produced in nuclear explosions was used as a tracer to examine resin metabolism in Pinus radiata. Annual rings of trees were ground and the resin extracted. The C/sup 12/: C/sup 13/ and C/sup 14/ ratio of each sample was determined. Results indicate that all the resin activity is considerably lower than that of the atmosphere at the time the ...

THE CLASSIFICATION AND DISTRIBUTION OF THE MYCORRHIZAS OF PINUS RADIATA
Australian Forestry, 1965SUMMARY Seven different types of mycorrhiza were collected from a stand of Pinus radiata D. Don growing at Mt. Macedon. Victoria. These were classified according to Dominik's colour key. One of the forms has not been described before. The distribution of these types along a random traverse was studied over a period of 14 months.

Somatic Embryogenesis in Pinus Radiata Don.
1995Pinus radiata (Monterey pine) is by far the most dominant plantation softwood in several Southern hemisphere countries. Recent figures indicate expanding acreage’s of ca. 700000 ha in Australia, ca. 1.3 million ha in Chile and ca. 1 million ha in New Zealand, these three countries accounting for most plantations of this species.

DAMAGE TO PINUS RADIATA BY CLIMATIC AGENTS
Australian Forestry, 1947SUMMARY From observations made, principally in the Australian Capital Territory, damage to Pinus radiata (Monterey pine) caused by various climatic agents is described. Low temperatures are considered to be responsible for needle discoloration in winter and dead tips and needles in certain cases in young trees, small frost cracks, frost rings and ...

Particleboards with Pinus radiata Bark
1991Mixtures of Pinus radiata D. Don back and wood particles for the production of particleboards were studied. Single layer boards with the following processing parameters were manufactured: Board thickness: 11 mm; Board density: 650 kg/m3 ; Adhesive content: 8% urea-resin solids, based on ovendry weight of particles; Bark content (%): 0; 10; 25; 40; 55 ...
