  1. Isolation, identification and molecular characterisation of an isolate of <em>Zucchini yellow mosaic virus</em> occurring in KwaZulu-Natal, South Africa

    Isolation, identification and molecular characterisation of an isolate of <em>Zucchini yellow mosaic virus</em> occurring in KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Zucchini yellow mosaic virus (ZYMV) is an economically important virus infecting cucurbits and has a worldwide distribution. In the Republic of South Africa, ZYMV has been reported as a major limiting factor to cucurbit production. The aim of this study...
  2. The ‘suitcase hypothesis’: Can entrainment of meroplankton by eddies provide a pathway for gene flow between Madagascar and KwaZulu-Natal, South Africa?

    The ‘suitcase hypothesis’: Can entrainment of meroplankton by eddies provide a pathway for gene flow between Madagascar and KwaZulu-Natal, South Africa?

    Item type: Journal Article • Journal: African Journal of Marine Science
    Similarities in the marine fauna found off the coasts of southern Madagascar and KwaZulu-Natal Province (KZN), South Africa, led to the development of the ‘suitcase project,’ with the aim of establishing whether eddies that form off southern Madagascar may package...
  3. Financial Decision Criteria and Real Price Changes

    Item type: Journal Article • Journal: South African Forestry Journal
    General price indices such as the Consumer Price Index (CPI) or the Production Price Index (PPI) represent the weighted average of prices of a large number of goods and services. Such price indices therefore cannot accurately measure the changes in...
  4. Determination of the Long-term Profitability of Forestry Projects

    Item type: Journal Article • Journal: South African Forestry Journal
    A planned forestry project which appears to be profitable for one rotation will not necessarily be profitable in the long term. It can change to an unprofitable project after a number of profitable rotations. Sustained profitability will depend on the...
  5. 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...
  6. Chemical Evaluation of Leaf Fibre Residues from Tropical Tree Legumes—a Wealth in Social Perspective

    Item type: Journal Article • Journal: South African Forestry Journal
    Leaf fibre residues obtained as a by-product during bulk extraction of leaf protein meal from three tropical forest trees viz. Albizzia procera Benth., Dalbergia sisso Roxb. and Delonix regia Raf. were analysed for their chemical and mineral composition. The fibres...
  7. Towards a method of assessing the veld condition of the valley bushveld in the Eastern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Currently, no technique is available for assessing the condition of Valley Bushveld in the Eastern Cape. The objective of this investigation was to develop a method of scoring bushveld according to its productive condition. It was established, through principal component...
  8. Die produksie van smutsvingergras in die wes‐transvaal<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die produksie van Smutsvingergras (Digitaria eriantha) is in yerskeie proewe in die Hoëveldstreek, op Potchefstroom, in die verlede bepaal. Hierdie proewe is oor ‘n lang periode op verskillende grondsoorte en met verskillende bemestingspeile uitge‐voer. Alle resultate is saamgevoeg en met...
  9. A gradient analysis of grassed mountain catchments in the natal Drakensberg

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An indirect gradient analysis was carried out on vegetation and environmental data from the Mdedelelo Wilderness Area of Cathedral Peak State Forest in Highland Sourveld. Vegetation ordination axes were correlated with environmental variables deduced to have influenced species‐composition. Altitude proved...
