  1. 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...
  2. 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...
  3. 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...
  4. <em>Pinus</em> saw timber tree optimisation in South Africa: a comparison of mechanised tree optimisation (harvester/processor) versus current manual methods

    <em>Pinus</em> saw timber tree optimisation in South Africa: a comparison of mechanised tree optimisation (harvester/processor) versus current manual methods

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Both Cut to Length (CTL) and Full Tree/Tree Length (FT/TL) ground-based systems are used to harvest pine in South Africa. The fully mechanised CTL system is the most recently introduced system in South Africa. One of the reasons for the...

    Comparison of wood, fibre and vessel properties of drought-tolerant eucalypts in South Africa<xref ref-type="fn" rid="F0000"/>

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Three drought-tolerant eucalypt genotypes have been investigated for a broad spectrum of properties to provide a basis for comparison on their suitability for various end-uses. The genotypes included were a Eucalyptus grandis × E. camaldulensis hybrid, E. gomphocephala and E...
  6. 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...
  7. Voluntary intake of several planted pastures by sheep and an assessment of NDF and IVDOM as possible predictors of intake

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The aim was to study the quality and quantity of pasture selected by sheep on various planted pastures. A further aim was to assess NDF and IVDOM as easy measurable parameters for use in equations to predict intake. Pasture samples...
  8. Utilization of <em>Lolium multiflorum</em> by sheep 1. Influence of dry matter content and correlated factors on voluntary intake

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The intake by young sheep of Lolium multiflorum cv. Midmar (ryegrass) with dry matter (DM) contents of between 10.2% and 20.5% was studied. Intake was measured on pasture, while at the same time herbage was cut and fed either fresh...
  9. Die invloed van triadimenol en karboksien op ontkieming en opbrengs van koring

    Die invloed van triadimenol en karboksien op ontkieming en opbrengs van koring

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die koleoptielgroei van ses koringkultivars waarvan die saad behandel is met triadimenol en karboksien is onder gekontroleerde toestande gemeet. Onder veldtoestande is twee kultivars wat met dieselfde saadbehandelingsmiddels behandel is, by twee plantdieptes vergelyk. Met triadimenol is korter koleoptiellengtes verkry...
  10. Comparison of cotton (<em>Gossypium hirsutum</em> L.) yield and fibre properties over locations and seasons

    Comparison of cotton (<em>Gossypium hirsutum</em> L.) yield and fibre properties over locations and seasons

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The cotton breeding program in the Republic of South Africa is conducted at the localities Loskop, Upington and Vaalharts. Preliminary results from breeding trials indicated that a finer but more mature fibre could be produced at Vaalharts as compared to...
