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 کاملDimensional Changes of Tracheids during Drying of Radiata Pine (Pinus radiata D. Don) Compression Woods: A Study Using Variable-Pressure Scanning Electron Microscopy (VP-SEM)
Variable-pressure scanning electron microscopy was used to investigate the dimensional changes in longitudinal, tangential and radial directions, on wetting and drying, of tracheids of opposite wood (OW) and three grades of compression woods (CWs), including severe CW (SCW) and two grades of mild compression wood (MCW) (MCW1 and MCW2) in corewood of radiata pine (Pinus radiata) saplings. The CW...
متن کاملAbove-ground biomass equations for Pinus radiata D. Don in Asturias
Aim of the study: The aim of this study was to develop a model for above-ground biomass estimation for Pinus radiata D. Don in Asturias. Area of study: Asturias (NE of Spain). Material and methods: Different models were f itted for the different above-ground components and weighted regression was used to correct heteroscedasticity. Finally, all the models were refitted simultaneously by use of ...
متن کاملVariation in gene expression profile with aging of Pinus radiata D. Don
Phase change in higher plants, from juvenile to mature, affects the reproductive competence, morphology and growth rate, as well as the regenerative potential of tissue explants. However, in conifers these changes can be achieved before the onset of flowering and at the beginning of the seed production. Early maturational changes in conifers are very obvious, severe and overall irreversible [1]...
متن کاملTHE EFFECT ON SEED GERMINATION OF VOLATILES FROM Pinus radiata LITTER
Pinus radiata D. Don is an important tree in New Zealand where it is widely grown for timber and, to a lesser extent, in association with pasture species. In pure stands of P. radiata in Canterbury, poor development of undergrowth may in part be caused by volatile inhibitory substances released from the decomposing litter. In previous work it was shown that vapour from incubated P. radiata litt...
