The role of fire in bush encroachment in Ithala Game Reserve.
The increase of woody vegetation (also known as bush or shrub encroachment) in savannas has become of global concern to conservationists and rangeland managers alike. Bush encroachment has been associated with a decrease ...
Some invetsigations on the responses to desiccation and exposure to cryogenic temperatures of embryonic axes of Landolphia kirkii.
Landolphia kirkii is scrambling shrub forming an integral part of the flora along the coastal areas of north-eastern South Africa. The non-sustainable harvesting of fruit as food source, by monkeys and rural communities ...
In vitro regeneration and secondary metabolites in cyrtanthus species.
Perennial geophytes form part of the diversified flora in southern Africa. The traditional medicinal system, integrates various plant components in the treatment of diverse ailments. In South Africa, bulbs are part of the ...
Development of strategies towards the cryopreservation of germplasm of Ekebergia capensis Sparrm. : an indigenous species that produces recalcitrant seeds.
The conservation of germplasm of indigenous plant species is vital not only to preserve valuable genotypes, but also the diversity represented by the gene pool. A complicating factor, however, is that a considerable ...
A comparative study of the plant ecology of three estuaries : Mgeni, Mhlanga and Mdloti.
The vegetation of the Mgeni Estuary, Mhlanga Estuary and Mdloti Estuary was analysed according to the Braun-Blanquet phytosociological method using quadrats of 4m2 and 25m2 in area placed subjectively and the Point-Centred ...

Tulbaghia (Alliaceae) is a genus of plants with medicinal, ornamental and nutritive value. Different plant parts such as roots, bulbs, leaves and flowers are used in the treatment of a variety of conditions. The bulbs of ...
The interaction between endophytic Fusarium species and Eldana saccharina (Lepidoptera) following in vitro mutagenesis for F. sacchari tolerance to control the borer in sugarcane.
Eldana saccharina is a major pest in the South African sugar industry. Stalk damage by this borer and infection of bored tissue by opportunistic fungi result in loss of biomass and sucrose content, respectively. Amongst ...
Effects of some of the procedural steps of cyropreservation on cryo-recalcitrant zygotic embryos of three amaryllid species producing desiccation-sensitive seeds.
Cryopreservation is the most promising method for the long-term conservation of germplasm of plants producing desiccation-sensitive seeds. While such seeds are generally termed recalcitrant in the context of conventional ...
