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 کاملAnalyses of basic crown-stem growth relationships in Radiata pine
The variability of wood properties is an important issue in the utilisation of wood and fibre. Over recent decades there has been increased emphasis on intensively managed, short rotation, plantation forestry, that produces larger proportions of so-called juvenile or core wood. This situation seems to have been aggravated by the shift to establishing forests on high-fertility farm sites, and ea...
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 کاملSummary We characterized a Pinus radiata D
We characterized a Pinus radiata D. Don putative ortholog to the Arabidopsis thaliana (L.) Heynh. SHORT-ROOT gene (AtSHR) and analyzed its expression in different organs during vegetative development and in response to exogenous auxin during adventitious rooting. The predicted protein sequence contained domains characteristic of the GRAS protein family and showed a strong similarity to the SHOR...
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]...
