  1. 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...
  2. 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...
  3. <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...
  4. 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.
  5. 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...
  6. 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...
  7. 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...
  8. Stimulation of Bud Production in <em>Eucalyptus globulus</em> by Paclobutrazol Application

    Item type: Journal Article • Journal: South African Forestry Journal
    Trunk injection of paclobutrazol (Clipper) significantly increased the bud crop on 7-year-old Eucalyptus globulus (Labill.) seed orchard trees, within one year of application. This is the first reported stimulation of reproduction to occur, with eucalypts, in the season of application...
  9. 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...
  10. The Effects of Phosphorus and Dolomitic Lime on the Production and Volumetrical Conversion Factors of <em>Eucalyptus grandis</em> Wood

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of phosphorus and dolomitic lime applications on the stacked wood volume, dry wood weight and form, bark and stacking factors of Eucalyptus grandis Hill ex Maiden trees are presented. The rates of phosphorus (0 kg, 200 kg and...
