  1. A single dominant <em>Ganoderma</em> species is responsible for root rot of <em>Acacia mangium</em> and <em>Eucalyptus</em> in Sumatra

    A single dominant <em>Ganoderma</em> species is responsible for root rot of <em>Acacia mangium</em> and <em>Eucalyptus</em> in Sumatra

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Ganoderma root rot is the most serious disease affecting commercially planted Acacia mangium in plantations in Indonesia. Numerous Ganoderma spp. have been recorded from diseased trees of this species and to a lesser extent Eucalyptus, causing confusion regarding the primary...
  2. The Application of Inorganic Fertilisers to Conditioned <em>Pinus radiata</em> Prior to Lifting as a Means of Improving Root Growth Capacity

    Item type: Journal Article • Journal: South African Forestry Journal
    A modified root growth capacity technique was used to evaluate the effect of the application of different types and quantities of fertilisers on the root growth capacity (RGC) of conditioned Pinus radiata seedlings. The experiment indicates that 0,05 g N...
  3. Root Systems of Some Southern Cape Indigenous Forest Trees

    Item type: Journal Article • Journal: South African Forestry Journal
    Root system form of forest trees were investigated and classified in the southern Cape indigenous forests. Windfalls of some of the dominant canopy species were inspected. Root systems were opened up by mechanical excavations. Tree species displayed the following general...
  4. 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...
  5. Root-shoot Growth Periodicity in <em>Ocotea bullata</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Periodicity in leaf fall, and in the growth of roots and shoots of Ocotea bullata was studied. Leaf fall of canopy trees was measured to establish the natural phenological pattern of mature trees. Shoot growth was measured on potted plants...
  6. Grazing of <em>raphanus sativus</em>. L (Japanese Radish)<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The performance of young woolled sheep was markedly better when grazing Japanese radish early in winter, when more leaf was available .Continuous grazing resulted in better performance than rotational or zero grazing.
  7. Soil factors affecting tree growth and root development in a citrus orchard

    Soil factors affecting tree growth and root development in a citrus orchard

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Tree- and root-growth parameters correlated well with a number of soil properties Useful relationships were established between unconfined penetrometer resistance, air capacity (at FWC), tree growth and root development.
  8. Die invloed van die beskikbaarheid van nutriënte en ontblaringsbestuur op die produksie van <em>digitar1a Eriantha</em> variëteit <em>Eriantha</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die invloed van verskillende peile van stikstof (N), fosfaat (P) en kalium (K) op die produksie en kwaliteit van Digitaria eriantha var. eriantha is in sandkultuur ondersoek. Verder is daar ook gekyk na die invloed van drie intensiteite van ontblaring...
  9. Relations between soil factors and herbage yields of natural grassland on sandy soils in the south‐eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Forty systematically‐placed observation points were established in a 1.5‐ha area of floristically unifoim veld in which productivity varied spatially. At each point grass yields were determined by harvesting quadrats at eight‐week intervals during the growing season, and the volumetric water...
  10. Aluminium uptake sites in the primary root of <em>Zea mays</em> L.

    Aluminium uptake sites in the primary root of <em>Zea mays</em> L.

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Histochemical studies of the chronological sequence involved in the uptake of Al by the primary root of Zea mays L., cv. TX 24, showed the primary sites of Al uptake to be the peripheral cells of the root cap and...
