In vitro propagation of Scilla natalensis planch.
In South Africa, large quantities of Scilla natalensis are harvested from wild populations and sold as traditional medicine, which is reducing the density, distribution and genetic diversity of wild populations. The ...

Eucomis (Family Hyacinthaceae) are deciduous geophytes with long, narrow leaves and erect, densely packed flower spikes. The bulbs are greatly valued in traditional medicine for the treatment a variety of ailments, and ...
A taxonomic reassessment of the subtribe Asciepiadinae (Asclepiadaceae) in Southern Africa : Vol. 2.
This study extends an earlier M.Sc. research project on the narrow-leaved species of the genus Asclepias L. (30 species) to cover the entire subtribe Asclepiadinae sensu K. Schum. in southern Africa- (182 species in 23 ...
Population genetics of the striped-mouse, Rhabdomys Pumilio (Sparrman, 1784)
The striped-mouse, Rhabdomys pumilio, is widely distributed throughout southern Africa within a variety of habitats and rainfall regimes. It is found at sea level in the Eastern and Western Cape regions and at altitudes ...
Comparision of two promoters driving transgene expression in water-stressed sugarcane.
For the expression of transgenes in plant cells, appropriate promoter sequences have to be introduced upstream of the gene to ensure efficient transcription. Tissue- or signal-responsive promoters are in high demand in ...
Vitamin B-6 deficiency : biochemical and physiological changes with special emphasis on zinc status
Abstract available on PDF file.
The development of in vitro rooting systems for cold-tolerant Eucalyptus grandis x nitens clones and the assessment of the hydraulic efficiency of roots produced by in vitro vs. cutting propagation.
Hybrid clones of the fast-growing Eucalyptus grandis and cold-tolerant E. nitens (GN clones) have been identified by the South African Forestry Industry as being highly suitable for plantations in cold-dry marginal areas. ...
