  1. Impact of Wood Quality Assessments on Future Fibre Resources in the Pulp and Paper-making Industry

    Item type: Journal Article • Journal: South African Forestry Journal
    Recent evidence from research in Europe has indicated that individual trees can be sampled for their pulping properties by the removal of small quantities (5–50 g) of wood at about breast height (1,3 m above ground). Work began at Sappi's...
  2. Effect of Initial Spacing and Thinning on Some Wood Properties of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    A study was made of the effect of thinning intensity on wood density and some wood anatomical properties and their within-tree variation patterns, as well as the extent to which the development of growth-stress splits in logs and sawn boards...
  3. The Wood Properties and Qualities of Three South African-Grown Eucalypt Hybrids

    Item type: Journal Article • Journal: South African Forestry Journal
    Hybridisation is becoming an increasingly important technique in tree breeding to improve yields, adaptability and wood quality. In this study, sample material from crosses of Eucalyptus grandis with E. tereticornis, E. camaldulensis and E. urophylla established on sites of which...
  4. The effect of planting density on the wood quality of South African-grown <em>Eucalyptus grandis</em>

    The effect of planting density on the wood quality of South African-grown <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    This paper presents the results of a wood property and sawn board quality study performed on disc samples and sawlogs taken from a 23-year-old Eucalyptus grandis Nelder 1a spacing trial at J.D.M. Keet plantation near Tzaneen. Ten trees from each...
  5. The wood properties and sawn-board quality of South African-grown <em>Pinus maximinoi</em> (HE Moore)

    The wood properties and sawn-board quality of South African-grown <em>Pinus maximinoi</em> (HE Moore)

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    This report summarises results of past research in South Africa on the wood properties and qualities of P. maximinoi, supplemented by results of a study performed recently on an approximately 15.5-year-old provenance trial at Wilgeboom after it had been severely...
  6. Fourteen Year Performance of <em>Eucalyptus</em> Species/Provenances, <em>Casuarina equisetifolia, Leucaena leucocephala</em> and <em>Senna siamea</em> at Michafutene, Mozambique

    Fourteen Year Performance of <em>Eucalyptus</em> Species/Provenances, <em>Casuarina equisetifolia, Leucaena leucocephala</em> and <em>Senna siamea</em> at Michafutene, Mozambique

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Variation in performance of several Eucalyptus species/provenances/land races, Casuarina equisetifolia, Leucaena leucocephala and Senna siamea was evaluated in two 14—year old trials planted at Michafutene, Mozambique. At the age of 6, 10, and 14 years, data were collected of survival,...
  7. Variation in Wood Density and Tracheid Length in <em>Pinus patula</em> grown in Zimbabwe

    Variation in Wood Density and Tracheid Length in <em>Pinus patula</em> grown in Zimbabwe

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Within-tree variation of wood density was studied for 14-and 25-year-old Pinus patula Schiede & Deppe trees grown at two plantation sites in Zimbabwe. Three trees of each age per site were selected and disc samples obtained at six relative height...
  8. A Comparison of the kraft pulp properties of P. <em>elliottii</em> and the <em>P. elliottii</em> x <em>P. caribaea</em> var. <em>hondurensis</em> hybrid grown in Queensland, Australia

    A Comparison of the kraft pulp properties of P. <em>elliottii</em> and the <em>P. elliottii</em> x <em>P. caribaea</em> var. <em>hondurensis</em> hybrid grown in Queensland, Australia

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The interspecific hybrid between P. elliottii var. elliottii and P. caribaea var. hondurensis has recently been accepted for planting operationally as an alternative to P. elliottii by Sappi in South Africa. Some concerns have been expressed as to the suitability...
  9. The survival, growth and wood basic densities of 14 year old <em>Eucalyptus camaldulensis</em> at Michafutene, Mozambique

    The survival, growth and wood basic densities of 14 year old <em>Eucalyptus camaldulensis</em> at Michafutene, Mozambique

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    A species and provenance trial for Eucalyptus (11 Eucalyptus camaldulensis provenances and 1 Eucalyptus tereticornis) was established at Michafutene, Mozambique in March 1982. Data on survival, growth, yield, stem characteristics and wood basic density have been analysed. Assessments were done...
  10. Variation in Wood Properties of <em>Eucalyptus nitens</em> in a Provenance Trial on the Eastern Transvaal Highveld in South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    Eucalyptus nitens is one of the four important cold-tolerant eucalypts grown for mining timber and pulpwood on the eastern Transvaal highveld in South Africa. In 1983 an active genetic improvement programme was initiated to improve growth rate, stem form and...
