  1. <em>In Vitro</em> Propagation of <em>Eucalyptus radiata</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    In vitro propagation of Eucalyptus radiata is described. Low rates of in vitro plant multiplication were achieved with most. tested E. radiata clones on Nitsch & Nitsch (1967) medium (NN-67), supplemented with indole butyric acid. (IBA), kinetin (KIN) and 6-benzyl...
  2. Micropropagation <em>of Eucalyptus radiata ssp. radiata</em> Using Explants from Mature and Coppice Material

    Item type: Journal Article • Journal: South African Forestry Journal
    Nodes from young field-grown coppice regrowth and branches of a mature tree of Eucalyptus radiata ssp. radiata were cultured on a MS medium containing BA and NAA. BA at 0,5 mg/ℓ and NAA at 0,01-0,1 mg/ℓ were most effective in...
  3. Effect of Anti-Fungal Agents on <em>In Vitro</em> Cultures of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Young, small shoot explants of E. grandis were multiplied in the presence of 0,5 and 1 g/ℓ benomyl, 0,25 and 0,5 g/ℓ chlorothalonil, 0,36 and 0,72 g/ℓ propamocarb hydrochloride and 0,002 5 g/ℓ Amphotericin B. The multiplied shoots were then...
  4. Strategies for the selection of uncontaminated <em>Eucalyptus</em> explants for shoot multiplication in a temporary immersion system (RITA<sup>®</sup>) in a commercial laboratory

    Strategies for the selection of uncontaminated <em>Eucalyptus</em> explants for shoot multiplication in a temporary immersion system (RITA<sup>®</sup>) in a commercial laboratory

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The potential high yields of Eucalyptus shoot multiplication achieved with a temporary immersion culture system such as RITA® are compromised by losses caused by microbial contamination particularly bacteria, characteristic of the explants used to initiate the cultures. Disinfection of the...
  5. <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...
  6. Analysis of differences in field performance of vegetatively andseed-propagated <em>Eucalyptus</em> varieties II: vertical uprooting resistance

    Analysis of differences in field performance of vegetatively andseed-propagated <em>Eucalyptus</em> varieties II: vertical uprooting resistance

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The aim of this study was to establish whether roots of micropropagated Eucalyptus grandis× E. nitens differ in their vertical uprooting resistance and architecture when compared with those of macropropagated E. grandis× E. nitens and seed-propagated E. grandis and E...
  7. Analysis of differences in field performance of vegetatively and seed-propagated <em>Eucalyptus</em> varieties I: survival and leaf gas exchange

    Analysis of differences in field performance of vegetatively and seed-propagated <em>Eucalyptus</em> varieties I: survival and leaf gas exchange

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The aim of this study was to compare survival rates and leaf gas exchange of micro- and macro-propagated Eucalyptus grandis × E. nitens, and seed-propagated E. grandis and E. nitens, at a site in Hilton, KwaZulu-Natal, South Africa, where the...
  8. <em>In vitro</em> biomass accumulation of calli and root enhancement of <em>Leucas aspera</em> (Willed) Linn. under stress conditions

    <em>In vitro</em> biomass accumulation of calli and root enhancement of <em>Leucas aspera</em> (Willed) Linn. under stress conditions

    Leucas aspera is a high value medicinal plant in India, Java, Mauritius and Philippines. The effects of plant growth regulators effects on in vitro callus biomass accumulation and root enhancement were assessed using leaf and stem explants. Leaf and stem...
