Above-ground allometry, biomass and nutrient content of acacia mearnsii across four ages and three sites in the Kwazulu-Natal Midlands.
(2005)Acacia mearnsii (black wattle) is one of the few tree crops of which both timber and bark are utilised, with branches sometimes being collected for fuel wood. There is a great potential for nutrient loss from plantations ... -
Alkaloids of Catha Spp.
(2001)The levels of the psychoactive alkaloids S-(-)-cathinone and its primary metabolite cathine, consisting of the diastereomers (+) -norpseudoephedrine and (-)- norephedrine were determined in Catha edulis (Vahl) Forssk. ex ... -
Aluminium-induced gene expression in sugarcane roots.
(2002)Due to the increasing prevalence and severity of Al phytoxicity in certain regions of the South African sugar industry, a research programme has been initiated at SASEX to elucidate the molecular mechanisms by which ... -
Analysis of historical flowering data, investigations into aspects of pollen biology and selected biotechniques to complement sugarcane breeding in South Africa.
(2016)Abstract available in PDF file. -
Another culture of Solanum genotypes.
(1995)Being the third most cultivated crop in South Africa, potatoes are of great economic importance. As potatoes originated from cooler areas in the world, they do not easily adapt to South African conditions. The main ... -
Anti-inflammatory and anti-bacterial activity of South African Erythrina species.
(2000)An investigation was undertaken to determine whether Erythrina species indigenous to South Africa contained the same type of compounds as Erythrina species not found in South Africa and to determine whether they displayed ... -
The application of microsatellites to sugarcane parentage determination and varietal identification.
(2002)The use of microsatellite markers has matured and become commonplace for plant genome analyses and is now poised for widespread practical application in sugarcane. Sequence Tagged Microsatellite Site (STMS) amplification ... -
Aspects of avian thermal physiology and frugivory of indigenous and invasive fruits in South Africa.
(2014)Indigenous and invasive plants have long been recognised as an important food source for avian frugivores worldwide. It has been suggested that seed germination success can vary amongst avian and plant species and that ... -
Aspects of seed propagation of commonly utilised medicinal trees of KwaZulu-Natal.
(1996)Due to over-exploitation of commonly-used medicinal plants, mainly from KwaZuluNatal, because of ever-increasing human population growth, many of the useful medicinal plants are becoming depleted in their natural habitats. ... -
Aspects of the influence of temperature on the desiccation responses of seeds of Zizania palustris (Wild rice)
(1996)Seeds of wild rice (Zizania palustris var. interior) have been reported to show highest survival when dehydrated at 25 QC. It has also been reported that axis cells sustained least damage at this drying temperature. In ... -
Aspects of the invasion of southern tall grassveld by Aristida junciformis subsp. junciformis Trin. et Rupr.
(1998)Aristida junciformis subsp. junciformis Trin. et Rupr. is an indigenous, densely tufted, evergreen perennial grass associated with the degeneration of grasslands over large areas of South Africa. More than two hundred ... -
Aspects of the role of cytokinins in adventitious root formation.
(1996)The initiation and development of adventitious roots in cuttings are highly complex processes, influenced by both endogenous and exogenous factors. These vary from the environmental factors prior to the striking of the ... -
Aspects of the structure and functioning of the vegetation of the Hlatikulu Vlei.
(1996)Hlatikulu Vlei, situated in the foothills of the Natal Drakensberg, is one of the priority wetlands in KwaZulu-Natal, occupying an area of 733 Hectares. The importance of Hlatikulu Vlei lies in its functions to store ... -
Bark in traditional healthcare in KwaZulu-Natal, South Africa : usage, authentication and sustainability.
(2002)Healthcare in South Africa is polarised between western and traditional African systems of therapy. The latter is consulted by the majority of the population and therefore plays an integral role in the delivery of healthcare ... -
Biochemical and biophysical indicators of chilling tolerance in some species of Eucalyptus.
(1993)Although Eucalyptus species are indigenous to Australia, they have been successfully cultivated in South Africa, where they are mainly used in the mining and paper industries. With the explosion in these industries it ... -
Biochemical and ultrastructural changes associated with chilling injury in soybean seeds during imbibition.
(1996)Biochemical and ultrastructural changes associated with chilling injury (CI) in soybean seeds imbibed at 5°C and 25°C were investigated. Soybean seed germination appeared to be affected by chilling temperatures and initial ... -
Biological nitrogen fixation (acetylene reduction) associated with blue-green algal communities in the Mgeni estuary mangrove swamp.
(1987)Nitrogen fixation of blue-green algae associated with Avicennia marina (Forssk.) Vierh. pneumatophores and wet and dry surface sediments were investigated in the Mgeni Estuary mangrove swamp by means of the acetylene reduction ... -
Bioprospecting the flora of southern Africa : optimising plant selections.
(2005)Focused procedures which streamline and optimise plant prioritisation and selection in bioprospecting have the potential to save both time and resources. A variety of semiquantitative techniques were assessed for their ... -
Character variation and a cladistic analysis of the genus Lachenalia Jacq.f. ex Murray (Hyacinthaceae:Massonieae)
(2005)Morphological variation and a cladistic analysis of the large, endemic Southern African genus Lachenalia Jacq.f. ex Murray (Hyacinthaceae: Massonieae) is presented. Its close taxonomic relationship with the small endemic ... -
