An investigation into the potential of faecal sludge for plant production.
(2012)Abstract available in PDF file. -
An investigation of plants used in South Africa for the treatment of hypertension.
(1998)In most countries, as many as 15 to 25% of the adult population have raised blood pressure. People with hypertension, and even those with mild elevation of blood pressure, are at an increased risk of cardiovascular disease, ... -
Investigation of the processes involved during the photoinhibition of Zea mays L. seedlings.
(1990)It has been proposed that the protective systems (photorespiration, the anti-oxidant system and non-radiative energy dissipation) alleviate or reduce photoinhibitory damage under high light conditions. To investigate the ... -
Investigations into the responses of axes of recalcitrant seeds to dehydration and cryopreservation.
(2002)Achieving long-term storage of germplasm is critical for the conservation of plant biodiversity. Seed storage practices require that degradative reactions causing ageing be limited. By reducing the water content, cytoplasmic ... -
Investigations on the biological effects of smoke-water and smoke-derived compounds in agriculture and horticulture.
(2015)Abstract available in PDF file. -
Isolation and characterisation of senescence-related genes in carnations.
(1995)Senescence has been the subject of many studies, with the ultimate goal of increasing longevity of cut flowers, and for insight into the process of ageing. Senescence in the carnation is a complex phenomonen involving ... -
Leaf ultrastructural studies of Avicennia marina in response to salinity under natural conditions.
(2007)In Richards Bay Harbour, the mangrove Avicennia marina exhibits a distinct natural productivity gradient. The fringe site, which is regularly inundated twice daily by tides, supports luxuriant adult A. marina trees that ... -
Lipid peroxidation and ageing in seeds of cabbage and soya bean.
(1986)It has been suggested that lipid peroxidation is involved in the loss of seed vigour, although many attempts to examine the relationships between lipid peroxidation and seed vigour have proved equivocal. Studies were ... -
Lipid peroxidation and ageing in seeds of Glycine Max.
(1990)Six different lots of soya beans (Glycine max (L.) Merr.) were examined. Seed hydroperoxide levels were highly correlated with viability, but not with moisture contents. It was proposed that moisture contents may exert a ... -
Mating systems, insect pollination and chemical ecology of grassland Protea species (Proteaceae)
(2012)Major transitions between vertebrate and insect pollination systems have occurred many times during the angiosperm radiation and are associated with evolutionary modifications in floral traits. In the large ancestrally ... -
Mechanisms of desiccation tolerance in cryptogams.
(2002)In this study adaptations of bryophytes and lichens to desiccation stress were examined. The aim was to test whether desiccation tolerance in the selected species is constitutive or if desiccation tolerance could be ... -
Medicinal properties and growth of Merwilla natalensis.
(2003)Merwilla natalensis (Planchon) Speta is ranked as one of the most commonly sold medicinal plants at most of the informal medicinal plant markets found throughout South Africa. The increasing demand for medicinal plants ... -
Medicinal properties and micropropagation of Cussonia species.
(2000)Cussonia species (commonly known as Cabbage trees) are indigenous to South Africa and are used in traditional medicine to treat an assortment of diseases. Due to their attractive growth form, they are assets in ... -
The micromorphological and essential oil status of the foliar secretory structures of Ocimum obovatum E. Mey. ex Benth. subsp. obovatum (Lamiaceae)
(2011)Ocimum obovatum E. Mey ex Benth. var. obovatum is a traditionally used medicinal plant that grows along the KwaZulu-Natal coast and the western Cape of South Africa. The plant is noted for its hair restoration properties, ... -
Micromorphology and phytochemistry of the foliar secretory structures of Stachys natalensis Hochst. and development of an in vitro propagation protocol.
(2014)Many members of the genus Stachys have been used as ornamental plants, or as edible foods and, in a number of cultures, as traditional medicine. One such species, Stachys natalensis Hochst., is a perennial, straggling shrub ... -
Micropropagation and medicinal properties of Barleria greenii and Huernia hystrix.
(2009)The crisis of newly emerging diseases and the resistance of many pathogens to currently used drugs, coupled with the adverse side-effects of many of these drugs have necessitated the continuous search for new drugs that ... -
Micropropagation and secondary metabolites of Sclerocarya birrea.
(2009)Sclerocarya birrea (marula, Anacardiaceae) is a highly-valued indigenous tree in most parts of sub-Saharan Africa because of its medicinal and nutritional properties. The marula tree is adapted to the semi-arid conditions ... -
Micropropagation of Acacia mearnsii (de willd)
(1999)Multiple shoots were produced from nodal explants of thirty-day-old in vitro grown seedlings and from pretreated three, five- and nine-month-old greenhouse grown Acacia mearnsii plants, respectively. Explants were ... -
Micropropagation of date palm (Phoenix dactylifera L.) and papaya (Carica papaya L.)
(2000)Date palms (Phoenix dactylifera L.) and papayas (carica papaya L.) are two commercially important plantation crops. Their economic potential in South Africa and worldwide is increasing. However, due to disease, pests and ... -
Micropropagation of tulbaghia species.
(2011)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 ...
