  1. Micropropagation <em>of Eucalyptus radiata ssp. radiata</em> Using Explants from Mature and Coppice Material

    Item type: Journal Article • Journal: South African Forestry Journal
    Nodes from young field-grown coppice regrowth and branches of a mature tree of Eucalyptus radiata ssp. radiata were cultured on a MS medium containing BA and NAA. BA at 0,5 mg/ℓ and NAA at 0,01-0,1 mg/ℓ were most effective in...
  2. Growth, Yield and Timber Density of Short Rotation Coppice Stands of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of timing initial coppice reductions, number of reductions and final number of shoots per stool on growth and yield of Eucalyptus grandis are described. The basic data were obtained from three experiments situated in different climatic zones of...
  3. 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...
  4. Geno-Phenotypic Regression and Juvenile-Mature Correlations: Methodological Tools for Clonal Selection of <em>Eucalyptus</em> Hybrids in Congo

    Item type: Journal Article • Journal: South African Forestry Journal
    This paper discusses different ways to improve clonal selection and clonal variety propagation for the industrial plantations in Congo.
  5. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    The present paper is a continuation of the series dealing with the regeneration of Pinus radiata in the southern Cape Province. The study deals with post planting mortality and growth in response to the experimental treatments and planting site environment...
  6. The Genetic Control of Ring Width, Wood Density and Tracheid Length in the Juvenile Core of <em>Pinus patula</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Controlled crosses were made between six Pinus patula Schiede & Deppe plus trees selected in plantations. Six full-sib families and two commercial checks were planted in randomised complete block thrice-replicated progeny tests at two sites in Zimbabwe. At 7,5 years,...
  7. Chemical Evaluation of Leaf Fibre Residues from Tropical Tree Legumes—a Wealth in Social Perspective

    Item type: Journal Article • Journal: South African Forestry Journal
    Leaf fibre residues obtained as a by-product during bulk extraction of leaf protein meal from three tropical forest trees viz. Albizzia procera Benth., Dalbergia sisso Roxb. and Delonix regia Raf. were analysed for their chemical and mineral composition. The fibres...
  8. Basic Density, Tracheid Length and Strength Properties of Juvenile and Mature Wood of <em>Pinus patula</em> Grown in Tanzania

    Item type: Journal Article • Journal: South African Forestry Journal
    More than 70% of Tanzanian plantations consist of conifers, 60% of which are Pinus patula plantations. Juvenile wood is one of the most important sources of variability.
  9. Commercial Forestry on Signal Hill and Lion's Head, Cape Town

    Item type: Journal Article • Journal: South African Forestry Journal
    The history of afforestation with alien tree species on Signal Hill and Lion's Head, which form part of the Table Mountain Nature Reserve, Cape Town, was reconstructed. The natural vegetation comprises mostly West Coast Renosterveld which is considered the most...
  10. Soil factors affecting tree growth and root development in a citrus orchard

    Soil factors affecting tree growth and root development in a citrus orchard

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Tree- and root-growth parameters correlated well with a number of soil properties Useful relationships were established between unconfined penetrometer resistance, air capacity (at FWC), tree growth and root development.
