  1. Growth, Yield and Timber Density of Short Rotation Coppice Stands of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of timing initial coppice reductions, number of reductions and final number of shoots per stool on growth and yield of Eucalyptus grandis are described. The basic data were obtained from three experiments situated in different climatic zones of...
  2. Improving harvester estimates of bark thickness for radiata pine (<em>Pinus radiata</em> D.Don)

    Improving harvester estimates of bark thickness for radiata pine (<em>Pinus radiata</em> D.Don)

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Harvesters estimate bark thickness primarily from diameter over bark (DOB) and use it to estimate log volume and value. Harvester bark thickness estimation errors can reduce returns through poor bucking optimisation and out-of-specification logs. Radiata pine bark thickness data from...
  3. Genetic control of wood density and bark thickness, and their correlations with diameter, in pure and hybrid populations of <em>Eucalyptus grandis</em> and <em>E. urophylla</em> in South Africa

    Genetic control of wood density and bark thickness, and their correlations with diameter, in pure and hybrid populations of <em>Eucalyptus grandis</em> and <em>E. urophylla</em> in South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Tree diameter under and over bark at breast height (dbh), wood density and bark thickness were assessed on samples from control-pollinated families of Eucalyptus grandis, E. urophylla, E. grandis × E. urophylla and E. urophylla × E. grandis. The material...
  4. Effect of weeding and fertilisation on bark thickness and stem form of seven pine species on a low-elevation site at Usutu, Swaziland

    Effect of weeding and fertilisation on bark thickness and stem form of seven pine species on a low-elevation site at Usutu, Swaziland

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    On a low-elevation site at Usutu alternative species to Pinus elliottii, the species recommended in the past for such sites, were planted to evaluate growth differences. At rotation age, destructive stem profile analyses were conducted on some of the trees...
  5. Bark thickness and bark volume of <em>Pinus patula</em> in South Africa

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    In South Africa, tree volume tables and volume functions are usually based on the under bark stem volume. Many forest management studies, however, give the estimated over bark volume, in which case equations are required that estimate bark volume and...
  6. Seasonal Fluctuations and Diversity of Bark and Wood-boring Beetles in Lowland Forest: Implications for management Practices

    Item type: Journal Article • Journal: South African Forestry Journal
    The phenology and diversity of wood-living beetles attacking Cedrela mexicana, Khaya nyasica and Milicia excelsa were observed for one year with weekly window-flight-trap collections. A total of 150 species (10 known to be common pests of timber) were collected, most...
  7. Pine litter as substrate for propagation of vegetable transplants in trays

    Pine litter as substrate for propagation of vegetable transplants in trays

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The study evaluates the potential of pine litter for use as a substrate in the propagation of vegetable transplants in trays. Sub-optimum pH and electrical conductivity of pine litter were addressed by incorporating 10% feedlot manure by volume. The water...
  8. Progress and problems in rooting clonal <em>Carica papaya</em> cuttings

    Progress and problems in rooting clonal <em>Carica papaya</em> cuttings

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Carica papaya (L) is one of the few fruit crops that is still propagated commercially by seed. In the cool subtropical Pietermaritzburg area, a female clone ‘Honey Gold’ has been vegetatively propagated, by rooting leafy cuttings, for over 40 years...
  9. Effect of pine bark goat manure medium on seedling growth and N, P, K concentration of various vegetables

    Effect of pine bark goat manure medium on seedling growth and N, P, K concentration of various vegetables

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Pine bark compost is the medium of choice for seedling growers in South Africa due to its availability, low cost and good physical properties. However, it is acidic, has low electrical conductivity (EC) and nutrient content such that fortification and...
  10. A breeding strategy for <em>Acacia mearnsii</em> (black wattle) in South Africa

    A breeding strategy for <em>Acacia mearnsii</em> (black wattle) in South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The black wattle breeding programme that has served the wattle bark industry ofSouth Africa for the past five decades putlittleemphasis on improvingthe yield and quality ofthe timber, as timberwas not the product ofimportance. Today the timber is as important, ifnot...
