In Vitro Propagation of Eucalyptus radiata
Item type: Journal Article • Journal: South African Forestry Journal • Authors: D. G.M. Donald --- Department of Forest Science, Republic of South Africa D.J. Newton --- Department of Forest Science, Republic of South AfricaIn 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... -
Micropropagation of Eucalyptus radiata ssp. radiata Using Explants from Mature and Coppice Material
Item type: Journal Article • Journal: South African Forestry Journal • Authors: S.H. Chang --- Department of Forestry, RSA D. G.M. Donald --- Department of Forestry, RSA G. Jacobs --- Department of Horticulture, RSANodes 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... -
Effect of Anti-Fungal Agents on In Vitro Cultures of Eucalyptus grandis
Item type: Journal Article • Journal: South African Forestry Journal • Authors: M.P. Watt --- Department of Biology, South Africa B.A. Gauntlett --- Department of Biology, South Africa F.C. Blakeway --- Department of Biology, South AfricaYoung, 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... -
Strategies for the selection of uncontaminated Eucalyptus explants for shoot multiplication in a temporary immersion system (RITA®) in a commercial laboratory
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: M. P. Watt M. Banasiak T. Nicholson B. McAlisterThe 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... -
In vitro shoot multiplication and rooting from seedling explants of Pterocarpus angolensis in Zambia
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: Exildah Chisha-Kasumu AdamH. Price Steve WoodwardPterocarpus 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... -
Analysis of differences in field performance of vegetatively andseed-propagated Eucalyptus varieties II: vertical uprooting resistance
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: MEO Mokotedi --- School of Biological and Conservation Sciences, Biological Sciences Building, South Africa MP Watt --- School of Biological and Conservation Sciences, Biological Sciences Building, South Africa NW Pammenter --- School of Biological and Conservation Sciences, Biological Sciences Building, South AfricaThe 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... -
Analysis of differences in field performance of vegetatively and seed-propagated Eucalyptus varieties I: survival and leaf gas exchange
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: MEO Mokotedi --- School of Biological and Conservation Sciences, Biological Sciences Building, South Ring Road, Westville Campus, South Africa MP Watt --- School of Biological and Conservation Sciences, Biological Sciences Building, South Ring Road, Westville Campus, South Africa NW Pammenter --- School of Biological and Conservation Sciences, Biological Sciences Building, South Ring Road, Westville Campus, South AfricaThe 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... -
In vitro biomass accumulation of calli and root enhancement of Leucas aspera (Willed) Linn. under stress conditions
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Masilamani Sri Devi --- Department of Biotechnology, India Krishnamoorthy Vinothini --- Department of Biotechnology, India Pandian Arjun --- Department of Crop Sciences, South Africa Sudharshan Sekar --- Department of Biotechnology and Food Technology, South Africa Vuyo Mavumengwana --- Department of Biotechnology and Food Technology, South AfricaLeucas 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... -
Clonal microplant production of Corymbia maculata: effect of chemical sterilisation, plant growth regulator, gas exchange, activated charcoal and lighting
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Letícia Vaz Molinari --- Federal University of Lavras, Brazil Denys Matheus Santana Costa Souza --- Federal University of Lavras, Brazil Maria Lopes Martins Avelar --- Federal University of Lavras, Brazil Sérgio Bruno Fernandes --- Federal University of Lavras, Brazil Douglas Santos Gonçalves --- Federal University of Lavras, Brazil Dulcinéia de Carvalho --- Federal University of Lavras, Brazil Laura Ribeiro Atala --- Federal University of Lavras, Brazil Gilvano Ebling Brondani --- Federal University of Lavras, BrazilCorymbia maculata stands out for its resistance to biotic and abiotic stress and for its high-density wood, which is ideal for sawmills, sleepers, posts, firewood and charcoal. In vitro culture techniques can be used for large-scale clonal microplant production, given...
