Densified Radiata Pine for Structural Composites
A novel wood-based composite has been developed for use in structural applications. The process was designed to utilize rapidly-grown, low density, wood species. Plantation grown radiata pine is particularly well suited to this process. This is a laminated composite, where the lamina may be comprised of various materials, some of which have been treated with the viscoelastic thermal compression...
متن کاملSeed Production in Radiata Pine Clones on Four Different Sites
Seed production was studied in cones from 18 clones of radiata pine (Pinus radiata D. Don) replicated within and between four contrasting sites. At one site which was phosphate-deficient, number of full seeds per cone, along with cone volume #nd mean seed weight, was about one-third less than elsewhere. Empty seeds, although never completely absent, were prevalent only in occasional cones. Such...
متن کاملGravitropic response in radiata pine seedlings. Searching molecular keys
Coniferous trees develop compression wood in response to gravitropic stimuli. In nature this response can be generated by growth in slope, exposure to snow or high winds [1]. However, genes and molecular mechanism involved in this phenomenon are still unknown. We studied gene expression in response to gravitropic stimulation induced by 45° inclination in Pinus radiata D. Don one year old seedli...
متن کاملGraft Incompatibility in Radiata Pine in New Zealand
It has been generally considered that the incidence of graft incompatibility in Pinus is low compared with other genera. This paper cites an example of a sudden increase to more than 50% incompatibility in a 14-year-old seed orchard of Pinus radiata D. Don. The types of incompatibility present are examined and the implications for New Zealand's clonal seed orchard programme are discussed. INTRO...
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...
