  1. Determining Transpiration from <em>Pinus patula</em> Shoots—A Comparative Evaluation of the Cut-Shoot Method and Two Null-Balance Diffusion Porometers

    Item type: Journal Article • Journal: South African Forestry Journal
    The cut-shoot method and two types of small-chambered null-balance diffusion porometer were evaluated for suitability in studies of stomatal conductance and transpiration in Pinus patula. In the course of the cut-shoot evaluation, excised shoots were found to transpire at a...
  2. Evidence of Induced Nutrient Deficiency in Pine Plantings on Previously Cropped Lands

    Item type: Journal Article • Journal: South African Forestry Journal
    Widespread establishment failures of Pinus species have recently occurred on agricultural land acquired for commercial forestry in South Africa. These include about 10 000 ha of previously tilled soils in the north-eastern Cape belonging to Mondi Forests. A lettuce (Lactuca...
  3. The Genetic Control of Ring Width, Wood Density and Tracheid Length in the Juvenile Core of <em>Pinus patula</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Controlled crosses were made between six Pinus patula Schiede & Deppe plus trees selected in plantations. Six full-sib families and two commercial checks were planted in randomised complete block thrice-replicated progeny tests at two sites in Zimbabwe. At 7,5 years,...
  4. Modelling Diameter and Height Distributions through Dispersion Statistics in Even-aged Pine Plantations

    Item type: Journal Article • Journal: South African Forestry Journal
    Diameter and height distribution recovery, in combination with standlevel projection modelling, is generally used in Southern Africa for predicting growth and yield in even-aged pine plantations. A different approach for modelling diameter and height distributions for five pine species commercially...
  5. A Field Demonstration of the Effect on Streamflow of Clearing Invasive Pine and Wattle Trees from a Riparian Zone

    Item type: Journal Article • Journal: South African Forestry Journal
    Two portable weirs were used to quantify changes in streamflow following clearfelling of a dense stand of self-sown Pinus patula and Acacia mearnsii along a riparian zone on Kalmoesfontein, a SAPPI forest plantation south-east of Lydenburg, Eastern Transvaal. The weirs...
  6. Basic Density, Tracheid Length and Strength Properties of Juvenile and Mature Wood of <em>Pinus patula</em> Grown in Tanzania

    Item type: Journal Article • Journal: South African Forestry Journal
    More than 70% of Tanzanian plantations consist of conifers, 60% of which are Pinus patula plantations. Juvenile wood is one of the most important sources of variability.
  7. Prescribed under-canopy burning in <em>Pinus patula</em> plantations of the Mpumalanga highveld: The effects of fire on tree growth

    Prescribed under-canopy burning in <em>Pinus patula</em> plantations of the Mpumalanga highveld: The effects of fire on tree growth

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The effect of controlled undercanopy burning on tree growth has been studied under 16-year-old Pinus patula trees in Mpumalanga. Three fire intensity treatments and a control "no-burn" treatment, were applied to 1 ha plots. Average fuel depth was 42cm with...
  8. Root volume and raising period affect field performance of <em>Pinus patula</em> cuttings in South Africa

    Root volume and raising period affect field performance of <em>Pinus patula</em> cuttings in South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The propagation of pines through cuttings has become a commercial means of rapidly multiplying improved genetic material for operational use in forestry companies. Cuttings of pines are produced entirely in containers in South Africa. Containers, however, can negatively affect plant...
  9. Post establishment survival of <em>Pinus patula</em> in Mpumalanga, one year after planting

    Post establishment survival of <em>Pinus patula</em> in Mpumalanga, one year after planting

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Recent evidence indicated that the pathogen Fusarium circinatum might be contributing significantly to post-planting mortality. Consequently, sixteen experimental sample plots, widely distributed over many localities in Mpumalanga, were established over two growing seasons to quantify the extent of pest and...
  10. The effects of ontogenetic maturation in <em>Pinus patula</em> – Part II: Hedge cycling and field performance

    The effects of ontogenetic maturation in <em>Pinus patula</em> – Part II: Hedge cycling and field performance

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Early studies suggest that the juvenile period, during which favourable rooting can be achieved from Pinus patula seedling hedges, may be as short as 2 years from the date of sowing. If the effects of hedge maturation cannot be delayed,...
