  1. Absence of the 1BL/1RS chromosome translocation in the Kavkaz-derived wheat cultivar Tugela

    Absence of the 1BL/1RS chromosome translocation in the Kavkaz-derived wheat cultivar Tugela

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The South African bread wheat (Triticum aestivumL) cultivar Tugela (Kavkaz/Jaral'S') is highly resistant to stem rust caused by Puccinia graminis Pers. f. sp. tritici Eriks. & Henn. Based on pedigree analysis and infection types, it has previously been assumed that...
  2. Sucrose synthesis and translocation in <em>Zea mays</em> L. during early growth, when subjected to N and K deficiency

    Sucrose synthesis and translocation in <em>Zea mays</em> L. during early growth, when subjected to N and K deficiency

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    By omitting N and K either separately or in combination from the rooting medium, a nutrient stress condition was created with the aim of ascertaining whether sucrose synthesis or its translocation was linked to nutrient availability (N, K) in young...
  3. The effects of a water treatment residue on grain yield and nutrient content in seeds of common dry beans (<em>Phaseolus vulgaris</em> L. cv. Ghadra) grown in a dystrophic soil

    The effects of a water treatment residue on grain yield and nutrient content in seeds of common dry beans (<em>Phaseolus vulgaris</em> L. cv. Ghadra) grown in a dystrophic soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This glasshouse study investigated the grain yield and nutrient content of seed of common dry beans (Phaseolus vulgaris L. cv. Ghadra) grown in a dystrophic sandy soil treated with 0, 50, 100, 200 and 400 g kg−1 water treatment residue...
  4. Impact of water stress on growth reserves and re-growth of <em>Themeda triandra</em> (Forssk) following defoliation

    Impact of water stress on growth reserves and re-growth of <em>Themeda triandra</em> (Forssk) following defoliation

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The influence of water stress and defoliation on the concentration of total non-structural carbohydrates (TNCC) and water-soluble protein (WSPC) as growth reserves after defoliation were determined in the indigenous C4 semi-arid grass species Themeda triandra during three growth stages (vegetative,...
  5. The effects of fences and lions on the ecology of African wild dogs reintroduced to Pilanesberg National Park, South Africa

    The effects of fences and lions on the ecology of African wild dogs reintroduced to Pilanesberg National Park, South Africa

    Item type: Journal Article • Journal: African Zoology
    Wild dogs have been eradicated from most of South Africa. However, a large number of smaller isolated reserves offer the potential for metapopulation conservation management of this species through continued translocations among reserves. Wild dogs were released into the Pilanesberg...
  6. Phylogeography of oribi antelope in South Africa: evolutionary versus anthropogenic panmixia

    Phylogeography of oribi antelope in South Africa: evolutionary versus anthropogenic panmixia

    Item type: Journal Article • Journal: African Zoology
    The increased rate of human-driven change is a major threat to biodiversity. Although there is sufficient evidence to suggest that species notably alter their ranges, facilitation of such movement for larger vertebrate species often places burdens on management agencies. Oribi...
