Somatic embryogenesis in Pinus radiata
Somatic embryogenesis of Pinus radiata has been seen as an attractive alternative to traditional propagation methods. This is due to its potential for high multiplication rates and rejuvenation, as well as its compatibitity with molecular techniques. To date no commercial production of somatic …

Photosynthesis and transpiration in a dry-land Pinus radiata forest
… at the leaf and canopy scales in a dry-land Pinus radiata D. Don forest by combining gas exchange measurements with biophysical process-based models of photosynthesis, radiation transfer, and soil water balance. Responses of photosynthesis to leaf intercellular CO₂ concentration in two-year …

Lateral development in roots and shoots of Pinus radiata seedlings
… range of growth active substances are presented. Pinus radiata was chosen because of its availability, its role in forestry and its rapid and hardy growth. Although much is known about its shoot growth and silviculture and rooting of cuttings, only a limited amount of work has been concerned with …

A dendrochronological investigation of Pinus radiata from Silvermine Nature Reserve
Whole trunk cross sections of Pinus radiata were collected from Silvermine Nature Reserve, Cape Town. The site was located on a hill in the nature reserve where precipitation was assumed to be a limiting factor in tree growth. Ring widths along 82 radii on 41 samples were measured to the closest …

Structural changes to Pinus radiata wood lignin during kraft pulping and bleaching
… improved method for the isolation of lignin from Pinus radiata wood was developed. The method involves a three day enzymatic hydrolysis of ball milled wood, followed by a second ball milling stage. A combination of extraction and purification steps enables isolated yields of approximately 75% of …

Studies on the microbial ecology of soils from Pinus radiata (D. Don) forests
… Service became aware that stands of second crop Pinus radiata (D. Don) on some areas of the Moutere Gravel formation were showing slow growth and had a chlorotic appearance (Fig. 1.1). The second crop followed clear felling of mature P. radiata trees and were aged from 0 to 15 years (stone and …

Nutrient Cycling Between Litters and Soil after Fire in Native Woodland and Pinus radiata Plantations
… included Eucalyptus woodlands (‘native’) and Pinus radiata plantations (‘pine’); sampling in all of these reserves initially occurred four months after the fire with further samples collected as described in Chapters 2, 3, and 6. To address the knowledge gaps, a series of field activities and …

Genetic And Temporal Variation In Resource Exchange Between An Ectomycorrhizal Fungus, Rhizopogon Occidentalis, And Seedlings Of Pinus Radiata
… phosphorus resource exchange dynamics between Pinus radiata and an ectomycorrhizal fungus, Rhizopogon occidentalis, varied between native populations of Pinus radiata and over the first 64 weeks of the mycorrhizal mutualism. Using a mycocosm approach, the C:N and C:P exchange ratios were …

Water use of Pinus radiata D. Don on bare ground at the Lincoln agroforestry experiment, Canterbury, New Zealand
… positions of Clone 3 and Seedling trees of Pinus radiata genotypes grown in bare ground during early summer (September 14 to 30 November) 1994. The predawn and mid-day plant water potential of two genotypes was also evaluated. Soil water storage was monitored weekly using Time-domain …
