Effect of cultivar, seedling age and leaf clipping on establishment, growth and yield of pearl millet (Pennisetum glaucum) and sorghum (Sorghum bicolor) transplants
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: S. Mapfumo --- Department of Crop Science, Zimbabwe C. Chiduza --- Department of Agronomy, Faculty of Science and Agriculture, South Africa E.M. Young --- , UK F.S. Murungu --- Department of Agronomy, Faculty of Science and Agriculture, South Africa P. Nyamudeza --- , ZimbabweThis study explored the viability of intensifying pearl millet and sorghum production through use of nurseries and transplanting to address the problem of poor stand establishment. The experiments were carried out over two seasons, the 1999/2000 and 2000/2001 seasons in... -
Selection of Corymbia citriodora for pulp productivity
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: JT Brawner --- , Australia R Meder --- , Australia M Dieters --- School of Land, Crop and Food Sciences, Australia DJ Lee --- , AustraliaEvaluation of a series of spotted gum (Corymbia citirodora) progeny trials, established in the subtropical region of Queensland, Australia, was undertaken to provide information for the development of advanced-generation breeding populations suitable for pulp production. Measurements of growth at two... -
Effects of oil pollution on aquatic macroinvertebrate assemblages in Gabon wetlands
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: MR Vinson EC Dinger J Kotynek M DethierMacroinvertebrate assemblages from uncontaminated and contaminated sites in the Gamba Complex (Gabon) were compared, the latter sites having been subjected to ongoing oil spills since the 1970s. Vegetation communities surrounding the sites included savannah, shrub–scrub, palm forest, gallery forest and... -
Dietary strategies to treat hyperhomocysteinaemia based on the biochemistry of homocysteine: a review
Item type: Journal Article • Journal: South African Journal of Clinical Nutrition • Authors: C. Nienaber-Rousseau --- Centre of Excellence for Nutrition, PotchefstroomHyperhomocysteinaemia is implicated in various diseases, including cardiovascular disease and cancer. Several conditions influence the concentration of homocysteine (Hcy), including demographic, genetic and lifestyle factors. With regard to the latter, dietary components may be manipulated as Hcy can be remethylated... -
Contribution of forest floor fractions to carbon storage and abundance patterns of arbuscular mycorrhizal fungal colonisation in a tropical montane forest
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: V Jeyanny --- Forest Plantation Programme, Malaysia MH Ahmad Husni --- Faculty of Agriculture, Malaysia B Siva Kumar --- Faculty of Agriculture, Malaysia K Wan Rasidah --- Forest Plantation Programme, Malaysia WC Suhaimi --- Forest Plantation Programme, MalaysiaForest floor carbon stocks, which include different components of litter, hemic and sapric materials, have not been empirically quantified in tropical montane forest, although they influence soil carbon (C) pools. To date, the contribution of arbuscular mycorrhizae in C sequestration... -
Tipping the scales: how fire controls the balance among functional groups in Angolan grasslands
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Paulina Meller --- , Germany Raquel Frazão --- , Germany Fernanda Lages --- , Angola Norbert Jürgens --- , Germany Manfred Finckh --- , GermanyFire plays an important role in the ecology of tropical grasslands globally. However, detailed studies comparing the response of plant functional groups to fire seasonality, and thus phenological timing, are scarce from humid Afrotropical grasslands. Such information, however, is crucial... -
