  1. Impact of seed burial depth on the emergence and growth of annual forage legumes

    Impact of seed burial depth on the emergence and growth of annual forage legumes

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The importance of evaluating the tolerance of forages to deeper seed burial is often overlooked. Therefore, this study evaluated the effects of increased seed burial depth on the emergence, vigour and early seedling growth of annual forage legume cultivars in...
  2. Selenium addition affects early seedling growth of <em>Medicago polymorpha</em> and <em>Trifolium subterraneum</em>, but not seed germination: a preliminary study

    Selenium addition affects early seedling growth of <em>Medicago polymorpha</em> and <em>Trifolium subterraneum</em>, but not seed germination: a preliminary study

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Little information regarding the effects of selenium addition on germination and early growth of annual leguminous forage crops exists. This study therefore evaluates the effects of selenium addition on the germination and early seedling growth of two annual forage legume...
  3. Seasonal variation of grassland basal cover

    Seasonal variation of grassland basal cover

    Preliminary results of a long‐term study of seasonal variation in grassland basal cover are presented. Seasonal stability appears to have been taken for granted but has not yet been shown experimentally. The experimental area is situated in the National Botanic...
  4. Morphology and ultrastructure of glandular and nonglandular trichomes on the leaves of <em>Athrixia phylicoides</em> (Asteraceae)

    Morphology and ultrastructure of glandular and nonglandular trichomes on the leaves of <em>Athrixia phylicoides</em> (Asteraceae)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Athrixia phylicoides is one of many plants from the Asteraceae family used as a traditional herbal medicine. Pharmacological evaluation of leaf extracts confirmed that the plant has anti-inflammatory, antihypertensive, narcotic and analgesic properties. The medicinal properties of plants are often...
  5. KWANTITATIEF EN/OF KWALITATIEF: DIE BEGRONDING VAN TAALADVIES?

    KWANTITATIEF EN/OF KWALITATIEF: DIE BEGRONDING VAN TAALADVIES?

    Item type: Journal Article • Journal: South African Journal of Linguistics
    Die gebrekkige tradisie van kwantitatiewe navorsing in 'n gebruikskundige omgewing lei dikwels daartoe dat algemene advies oor die gebruik van taalverskynsels, soos dié van die passiefkonstruksie byvoorbeeld, aan gebruikers gegee word.
  6. ON AN ELLIPTIC BOUNDARY VALUE PROBLEM ARISING IN MAGNETOHYDRODYNAMICS

    ON AN ELLIPTIC BOUNDARY VALUE PROBLEM ARISING IN MAGNETOHYDRODYNAMICS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Results are derived concerning the spectral properties of an elliptic boundary value problem arising in the mathematical theory of magnetohydrodynamics which are of basic importance for the further development of this theory.
  7. 'n Semantiese representasie (SR) van enkele Duitse plekname (PN) in sintaktiese verband

    'n Semantiese representasie (SR) van enkele Duitse plekname (PN) in sintaktiese verband

    Item type: Journal Article • Journal: South African Journal of Linguistics
    Plekname, dus ook Duitse plekname, kan as taaltekens onderskei word wat uit enige of verskillende sintaktiese kategoriee of rededele kan bestaan. Hulle vertoon onder andere sekere grammatiese betekenisse soos morfosintaktie-se relasies en het relevansie in 'n semanties-pragmatiese konteks waarvan die...

    Møller, A. Pape. 2000. Sexual selection and conservation: a Paleartic-African perspective. Ostrich 71 (1): 361
  9. Self-adjoint fourth order differential operators with eigenvalue parameter dependent boundary conditions

    Self-adjoint fourth order differential operators with eigenvalue parameter dependent boundary conditions

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We consider the eigenvalue problem y (4)(λ,x) − (gy′)′(λ,x) = λ 2 y(λ,x) with separated boundary conditions B j (λ)y = 0 for j = 1,…,4, where g ∈ C 1[0, a] is a real valued function, B...
  10. Delays in presenting for tuberculosis treatment associated with fear of learning one is HIV-positive

    Delays in presenting for tuberculosis treatment associated with fear of learning one is HIV-positive

    Item type: Journal Article • Journal: African Journal of AIDS Research
    A cornerstone of tuberculosis (TB) control is early diagnosis and treatment. The first hurdle that prospective TB patients must overcome is to present at a public health clinic for treatment. The Global Plan to Stop TB addresses the new challenges...
