  1. The function of regreening in yellow female <em>Leucadendron</em> (Proteaceae)

    The function of regreening in yellow female <em>Leucadendron</em> (Proteaceae)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    What do female Leucadendron stand to gain by regreening their involucral leaves rather than discarding them after flowering? Regreening of involucral leaves could contribute to the carbon budget and/or protect the developing cone-shaped inflorescence during seed development. This was determined...
  2. Die wiskundige simulering van koolhidraattranslokasie in natuurlike grasveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die groeifunksies benodig vir die simulasie van produksie van ‘n Themeda triandra‐grasveld met behulp van die PUTU 11 simulasiemodel is ontwikkel. Vir die ontwikkeling van die model is die veldproduksiedata van die 1980/81 groeiseisoen gebruik waarna dit suksesvol, vir drie...
  3. Influence of temperature during the preceding growth period of lucerne on its regrowth at different temperatures

    Influence of temperature during the preceding growth period of lucerne on its regrowth at different temperatures

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    One-year-old lucerne (Medicago sativa L. cv. ‘Vernal’) plants were grown to first flower through three cuttings in three temperature regimes, H (33°C day/24°C night), W (27718°C) and C (21712°C), to ascertain the influence of temperature preceding defoliation on subsequent growth...
  4. Tolerance of six Namaqualand pioneer species to saline soil conditions

    Tolerance of six Namaqualand pioneer species to saline soil conditions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Saline soils pose a great problem to reclamation of mined areas in arid regions. Experiments were carried out in order to determine the tolerance of six Namaqualand pioneer species to varying levels of salinity. Both perennial and ephemeral species were...
  5. Seasonal variations in carbohydrate content of <em>Carica papaya</em> plants

    Seasonal variations in carbohydrate content of <em>Carica papaya</em> plants

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Monthly samples were collected of roots, stems, petioles and leaf blades of clonal female ‘Honey Gold’ papaw (Carica papaya L.) plants, in the cool subtropical Pietermaritzburg area, to study any seasonal variations in carbohydrate content of this tropical plant which...
  6. The effect of defoliation environment on primary growth allocation and secondary tiller recruitment of two bunchgrasses

    The effect of defoliation environment on primary growth allocation and secondary tiller recruitment of two bunchgrasses

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Compositional shifts of bunchgrass species in the Southern Tall Grassveld in response to different combinations of non-selective mowing and burning appear to reflect differences in growth strategy among species, but there are few studies of South African grasses designed to...
  7. Effects of herbivory on above- and below-ground biomass partitioning in two arid-zone dwarf shrubs

    Effects of herbivory on above- and below-ground biomass partitioning in two arid-zone dwarf shrubs

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Biomass partitioning by arid-zone dwarf shrubs between above- and below-ground fractions could be influenced by plant adaptations to herbivory. The response of potted Indigofera spinosa and I. cliffordiana to heavy and moderate top defoliations, compared to non-defoliated controls, was investigated...
  8. Wood supply and forest regeneration consequences of integrated log allocation in western Kenya

    Wood supply and forest regeneration consequences of integrated log allocation in western Kenya

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The present system of log sales from softwood plantations in Kenya is by stumpage to single product mills. This harvesting system leads to pulping of large diameter logs while allocation of small diameter logs to sawmills is a major cause...
  9. Water use efficiency in South African <em>Eucalyptus</em> plantations: A review

    Water use efficiency in South African <em>Eucalyptus</em> plantations: A review

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The relation between rainfall and Eucalyptus stem growth is investigated using data recorded at three ICFR espacement trials in kwaZulu-Natal. These data show that, for a given rainfall amount, large differences in stem growth may occur at different sites. The...
  10. Commercial Fishing Rights Allocation in Post-apartheid South Africa: Reconciling Equity and Stability

    Commercial Fishing Rights Allocation in Post-apartheid South Africa: Reconciling Equity and Stability

    Item type: Journal Article • Journal: African Journal of Marine Science
    The fundamental policy and regulatory framework for a post-apartheid dispensation to manage commercial fisheries in South Africa was put in place with the publication of the White Paper on Marine Fisheries Policy in 1997, and the enactment of the Marine...
