  1. 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...
  2. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    Part 4 of the series of papers concerning the regeneration of Pinus radiata deals with characteristics of the planting stock. Such studies are motivated by the necessity of evaluating different planting stock alternatives for a variety of operational environments. This...
  3. The Effect of Site Preparation and Tending on the Growth of <em>Pinus radiata</em> in the Southern Cape: Five Year Results

    Item type: Journal Article • Journal: South African Forestry Journal
    This paper details the latest results of site preparation and tending experiments in Pinus radiata on regenerated sites, on both Kruisfontein Plantation in the Southern Cape District of the Western Cape Forest Region and Blueliliesbush Plantation in the Tsitsikamma Forest...
  4. Theaflavin values of various tea clones and selections grown in the northern Transvaal

    Theaflavin values of various tea clones and selections grown in the northern Transvaal

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Different grades of black tea of several clones and selections from a tea estate in the northern Transvaal were tested for theaflavin (TF) content. In the pekoe dust (PD) grade there were no significant differences in TF values. In the...
  5. The inheritance of drought resistance characteristics in grain sorghum seedlings

    The inheritance of drought resistance characteristics in grain sorghum seedlings

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A factorial crossing method was used to study the inheritance of and the relationship between characteristics which are related to drought resistance in grain sorghum seedlings. The potential for improving drought resistance in grain sorghum seedlings was verified by the...
  6. The inheritance of seedling growth rate in grain sorghum

    The inheritance of seedling growth rate in grain sorghum

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The inheritance of growth rate in grain sorghum seedlings was studied in two factorial crossing systems. The presence of both additive and dominance genetic variation was indicated. The additive gene effects played a greater role. At least three genetic factors...
  7. Suitability of two types of plastic covering on mini-tunnels for paprika seedling production in warm areas

    Suitability of two types of plastic covering on mini-tunnels for paprika seedling production in warm areas

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A trial was conducted at the ARC-Roodeplaat Vegetable and Ornamental Plant Institute to determine the difference between the two types of plastic (clear and opaque) used as covering for mini-tunnels during paprika (Capsicum anuum L.) seedling production. Two cultivars (PapriKing...
  8. Effect of soil nutrient status on severity of seedling diseases and root rot of sorghum (<em>Sorghum bicolor</em>)

    Effect of soil nutrient status on severity of seedling diseases and root rot of sorghum (<em>Sorghum bicolor</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The hybrid NK283 was subjected to a range of nutrient element concentrations to determine their effect on predisposition of sorghum to seedling diseases and root rot. Emergence was not affected by soil nutrient status. Similarly N, P and K did...
  9. Effect of chemical seed treatment on the germination and seedling vigour of canola (<em>Brassica napus</em> var. <em>oleifera</em>)

    Effect of chemical seed treatment on the germination and seedling vigour of canola (<em>Brassica napus</em> var. <em>oleifera</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Incubation studies were conducted to determine effects of two chemical seed treatments (Cruiser & SA-combination) on the germination and seedling vigour of canola (cv. Varola 44) seed. Germination percentages of the Cruiser and SA-combination treated seeds were not significantly reduced...
  10. Effect of chemical seed treatment on the germination and seedling growth of canola under different soil conditions

    Effect of chemical seed treatment on the germination and seedling growth of canola under different soil conditions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Studies in a temperature controlled greenhouse were conducted to determine if phytotoxic effects of chemical seed treatments found in incubation studies also have an effect on the germination- and seedling vigour of canola (cv Varola 44) seed planted in simulated...
