  1. <em>In Vitro</em> Propagation of <em>Eucalyptus radiata</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    In vitro propagation of Eucalyptus radiata is described. Low rates of in vitro plant multiplication were achieved with most. tested E. radiata clones on Nitsch & Nitsch (1967) medium (NN-67), supplemented with indole butyric acid. (IBA), kinetin (KIN) and 6-benzyl...
  2. 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...
  3. Performance of exotic tree species planted for poverty alleviation in Lesotho

    Performance of exotic tree species planted for poverty alleviation in Lesotho

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The people of Lesotho are among the poorest in the southern African region. The country is located in the Drakensberg mountains where winters are bitterly cold. Rural communities depend on woodfuels and cow dung for heating and cooking. Since the...
  4. Influence of Soil Organic Matter Content on the Responsiveness of <em>Eucalyptus grandis</em> to Nitrogen Fertiliser

    Item type: Journal Article • Journal: South African Forestry Journal
    It is widely recognised that the inherent nitrogen (N) mineralisation capacity of a soil is directly related to the organic matter content. Consequently, in estimating the N requirements of Eucalyptus grandis at planting this mineralisation potential must be taken into...
  5. The Relationship between Soil Water Status, Rainfall and the Growth of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Available soil water is recognised as the main factor influencing the growth of commercial plantations in southern Africa. This is of strategic importance as successive rotations of demanding species such as Eucalyptus grandis may be depleting the soil water reserves...
  6. Litterfall and Nutrient Release in Mature <em>Pinus radiata</em> in the South-western Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    Fast-growing plantations of conifers have replaced areas of mediterranean shrubland in the south-western Cape. This study arises from the need to quantify the impacts of major changes in primary productivity, litterfall, and nutrient cycling in terms of the site utilisation...
  7. Field Application of Carbosulfan for the Protection of Eucalypt Transplants from Termite Attack

    Item type: Journal Article • Journal: South African Forestry Journal
    Three trials were set up to test five different field application rates of 10% carbosulfan to protect eucalypt transplants from termite attack. A standard nursery treatment was also included in the trials.
  8. Comparison of <em>Eucalyptus grandis</em> Provenances and Seed Orchards in a Frost Frequent Environment

    Item type: Journal Article • Journal: South African Forestry Journal
    An international provenance trial of Eucalyptus grandis was established in southern Florida in 1980 and measured for growth and frost-tolerance through 8,8 years. The trial compared 20 Australian provenances 1) among themselves and 2) with seed orchard stock from Florida...
  9. 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...
  10. The Use of Roots to Test N, P and K Deficiencies in <em>Eucalyptus</em> Nutrition

    Item type: Journal Article • Journal: South African Forestry Journal
    Bioassays have been developed which can provide diagnostics of the nutritional status of trees. They measure the flux of N, P or Rb for K into roots from standard solutions where the rate of influx is inversely related to nutrient...
