Wood colour of radiata pine

2005
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.

Suspected copper deficiency in radiata pine

Plant and Soil, 1969
Growth disorders in 3-year-old radiata pine associated with very low copper concentrations in the foliage are described. The low concentrations of copper appear to have been nitrogen induced. The effect of remedial measures is being investigated.

Rooting micropropagated shoots from mature radiata pine

Canadian Journal of Forest Research, 1989
A reliable method of rooting shoots from mature micropropagated Pinusradiata D. Don has been developed. At the beginning of the research, difficulty in achieving consistent results was experienced. At the end of the series of described experiments, high rooting percentages (78%) were attained. The condition of shoots is important. Shoots that had been

Commercial micropropagation of radiata pine

1993
The 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.

Genetic gain trials of radiata pine

1991
Forest tree improvement is when control of parentage is combined with other forest management activities, such as site preparation or fertilization, to improve the overall yields and quality of products from forests. Overall results of tree improvement have been so good that we no longer have difficulty in selling tree improvement.

Provisional Tree Weight Tables for Radiata Pine

Australian Forestry, 1970
SUMMARY The fresh and dry weights of 25 components of 25 sample trees of radiata pine, Pinus radiata, D.Don, 5 to 18 years old, were measured. Equations were prepared by regression analysis to enable the weights of various combinations of components to be estimated from tree measurements of diameter at breast height over bark and total height.

Studies in Fire-Damaged Radiata Pine Plantations

Australian Forestry, 1969
SUMMARY Sapstain in standing pine burnt in March 19 u occurred within three months of the fire, but did not become a major problem until October 1965. Decay was not found in the sample plots. The extent of fungal attack was related to weather conditions; and an estimate is given of safe storage times for salvage perations.

S3 lignin concentration in radiata pine tracheids

Wood Science and Technology, 1987
Lignin concentration in the S3 layer of the tracheid wall of radiata pine was determined by making porosity measurements of hydrolysed cell walls using interference microscopy, with appropriate corrections for swelling. The mean S3 lignin concentration was approximately 53% v/v.

Determining prices for radiata pine clearwood

1984
Due to the widespread practise of pruning radiata pine trees in New Zealand there will be a substantial amount of timber free of knots to sell in the future. This timber is called "clearwood". A method is presented for determining what prices clearwood might fetch in any particular country/ market.
