Dimensional Stability of Particle Board and Radiata Pine Wood (Pinus radiata D. Don) Treated with Different Resins
Particleboard and solid wood stakes were treated with either an isocyanate or phenol formaldehyde resin and exposed in soil beds comprising three different soil types and two moisture contents. The treatments resulted in a marked improvement in the dimensional stability of particleboard but had no effect on solid wood. Higher moisture uptakes in stakes exposed in sandy soils indicated that the ...
متن کاملSuppression of Litter Decomposition by Mycorrhizal Roots of Pinus Radiata
Two experiments, designed to give more information about the suppression of litter decomposition by radiata pine (Pinus radiata D. Don) roots and their associated microflora, were carried out. In the first, root activity was reduced by cutting the boundaries of small areas of the forest floor in an unthinned stand. Samples collected after 3, 6, 9, and 12 months showed that less litter accumulat...
متن کاملPyrolysis Products of Pinus Radiata Bark
The yields of char, tar, and non-condensible gases from the pyrolysis of Pinus radiata D. Don bark were measured. Pyrolysis of bark, on a small preparative scale using an airacetylene flame, gave 48% char with ash content 3.5% (mainly aluminium, calcium, potassium, and silica), and recovered tar in 7% yield (on oven-dried bark equivalent). The major components of the pyrolysis tar were catechol...
متن کاملConversion of milled pine wood by manganese peroxidase from Phlebia radiata.
Purified manganese peroxidase (MnP) from the white-rot basidiomycete Phlebia radiata was found to convert in vitro milled pine wood (MPW) suspended in an aqueous reaction solution containing Tween 20, Mn(2+), Mn-chelating organic acid (malonate), and a hydrogen peroxide-generating system (glucose-glucose oxidase). The enzymatic attack resulted in the polymerization of lower-molecular-mass, solu...
متن کاملThe Abortion of Conelets in Pinus Radiata
Observations and records collected over a six-year period show that, in a seed orchard of Pinus radiata at Kaingaroa Forest, approximately half of all female strobili initiated abort during the first year after pollination. For an average clone this process of conelet drop starts at the time of receptivity, reaches a peak some four to six weeks later, and then decreases in intensity. This time ...
