  1. Bark removal for medicinal use predisposes indigenous forest trees to wood degradation in Zambia

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    Bark harvesting for medicinal purposes has become widespread in Zambia, mainly due to the high levels of poverty among the population. The injury caused to trees leads to wood deterioration as a result of insect damage and fungal infection. This...
  2. Germination of <em>Pterocarpus angolensis</em> DC. and evaluation of the possible antimicrobial action of the phloem sap

    Germination of <em>Pterocarpus angolensis</em> DC. and evaluation of the possible antimicrobial action of the phloem sap

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The Transvaal teak (Pterocarpus angolensis) is being over utilised in its natural habitat, although it is a protected tree in South Africa, Swaziland and Namibia. The phloem sap of this species has several traditional, medicinal uses and the wood is...
  3. <em>In vitro</em> shoot multiplication and rooting from seedling explants of <em>Pterocarpus angolensis</em> in Zambia

    <em>In vitro</em> shoot multiplication and rooting from seedling explants of <em>Pterocarpus angolensis</em> in Zambia

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Pterocarpus angolensis is a savanna tree species growing mostly in the southern part of Africa. Exploitation for its medicinal and commercial uses has led to diminishing of wild populations. Developing reliable in vitro protocols for propagation would enable mass production...
  4. The effect of the colonisation extent of arbuscular mycorrhizal fungi on the growth of pot grown <em>Pterocarpus angolensis</em> seedlings

    The effect of the colonisation extent of arbuscular mycorrhizal fungi on the growth of pot grown <em>Pterocarpus angolensis</em> seedlings

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The effect of the level of arbuscular mycorrhizal fungi (AMF) colonisation on the growth of Pterocarpus angolensis was studied. Mycorrhizal infected seedlings, showing either good or poor growth, under the same environmental conditions (temperature, humidity, light level) were analyzed for...
  5. Heritability of shoot die-back and root biomass in sixteen <em>Pterocarpus angolensis</em> (Fabaceae) half-sib families from Malawi, Namibia and Zambia

    Heritability of shoot die-back and root biomass in sixteen <em>Pterocarpus angolensis</em> (Fabaceae) half-sib families from Malawi, Namibia and Zambia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The experiment was conducted to ascertain narrow-sense heritability (h 2) and the family-within-provenance variation in shoot die-back, taproot length and root biomass of half-sib Pterocarpus angolensis families from Malawi, Namibia and Zambia. Provenances differed significantly in shoot die-back for both...
  6. Phenotypic variation among five provenances of <em>Pterocarpus angolensis</em> in Zimbabwe and Zambia

    Phenotypic variation among five provenances of <em>Pterocarpus angolensis</em> in Zimbabwe and Zambia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The feasibility of utilising morphological markers for determining existing provenance variation in the African savanna tree Pterocarpus angolensis was assessed. Five provenances were used: Mtao, Gokwe, Nyazura, Chesa (Zimbabwe) and Kapirimposhi (Zambia). Two weeks after germination, seedlings were inoculated with...
  7. RAPD markers demonstrate genetic diversity in <em>Pterocarpus angolensis</em> from Zimbabwe and Zambia

    RAPD markers demonstrate genetic diversity in <em>Pterocarpus angolensis</em> from Zimbabwe and Zambia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Understanding the availability, extent and apportionment of genetic variability in natural populations of the southern African savanna tree Pterocarpus angolensis can provide reliable information on the evolutionary history and phylogenetic relationships of P. angolensis populations. This information will aid strategies...
  8. Distribution and status of the desert-dwelling giraffe (<em>Giraffa camelopardalis angolensis</em>) in northwestern Namibia

    Distribution and status of the desert-dwelling giraffe (<em>Giraffa camelopardalis angolensis</em>) in northwestern Namibia

    Item type: Journal Article • Journal: African Zoology
    The population density and distribution of desert dwelling giraffes was estimated in three study areas in the Hoanib River catchment, northwestern Namibia. Giraffe population densities (0.01 giraffe/km2) were equal to the lowest recorded in Africa with population numbers fluctuating over...
  9. Comparison of the effects of mechanical scarification and gibberellic acid treatments on seed germination in <em>Pterocarpus angolensis</em>

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    Pterocarpus angolensis is a savanna tree species growing mostly in the miombo and undifferentiated woodlands found in the southern and central parts of Africa. Exploitation for its medicinal and commercial uses has led to a diminishing of wild populations. Artificial...
  10. Half-sib family variation in shoot and root traits of seedlings of <em>Pterocarpus angolensis</em> (family: Fabaceae; syn. Papilionaceae)

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    Phenotypic and genetic variation in shoot and root traits occurs between half-sib families from Malawi. Heritability was high for shoot height and root collar diameter (h 2 ≤ 0.90) while that for shoot and root traits was low to moderate...
