  1. Wood anatomical and chemical properties related to the pulpability of <em>Eucalyptus globulus</em>: a review

    Wood anatomical and chemical properties related to the pulpability of <em>Eucalyptus globulus</em>: a review

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Eucalyptus globulus is one of the most important hardwood species used by the pulp and paper industry due to its high pulp yield, high wood density, excellent fibre quality and good handsheet properties. However, the wood is a highly variable...
  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. 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...
  5. 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...
  6. 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...
  7. The effect of date of planting on the fibre properties of four cotton cultivars grown under irrigation

    The effect of date of planting on the fibre properties of four cotton cultivars grown under irrigation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effects of date of planting on the fibre properties of four cotton cultivars, Acala 1517–70, Albar 70C, Deltapine 5826 and Albacala CS-2, were investigated under irrigated conditions over a 3-year period near Groblersdal. Six dates of planting at fortnightly...
  8. Provisional assessment of quality components in lucerne (<em>Medicago sativa</em>) and white clover (<em>Trifolium repens</em>) using a near infrared reflectance spectrophotometer

    Provisional assessment of quality components in lucerne (<em>Medicago sativa</em>) and white clover (<em>Trifolium repens</em>) using a near infrared reflectance spectrophotometer

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A near infrared reflectance spectrophotometer (NIRS) with tilting filters was calibrated for the determination of the forage quality components, crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF), in vitro organic matter digestibility (IVOMD), dry matter (DM) and...
  9. The effects of environment on the relationship between cotton fibre properties and yarn characteristics

    The effects of environment on the relationship between cotton fibre properties and yarn characteristics

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Cotton fibre samples from three different localities were commercially processed into 15 and 30 tex ring spun yarns and 20, 30 and 50 rotor spun yarns. Multiple regression analyses were used to relate yarn tenacity and irregularity to the different...
  10. Registration of cotton (<em>Gossypium hirsutum</em> L.) cultivars Letaba, NIK2 and OR19

    Registration of cotton (<em>Gossypium hirsutum</em> L.) cultivars Letaba, NIK2 and OR19

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Letaba, NIK2 and OR19 were released for commercial cultivation in the R.S.A. in 1989. Letaba has potential as a dryland cultivar in the Springbok Flats and northern Natal. NIK2 is intended for cultivation under irrigation in the same areas and...
