Micropropagation of Brunsvigia undulata F.M. Leight.
Many South African medicinal plants face the threat of over-collection for use in traditional medicines. Many bulbous plants suffer as the whole plant is removed from the wild so that the bulb may be used for medicine. ...
Effect of nutrients and smoke solutions on seed germination and seedling growth of Tropical Soda Apple (Solanum viarum).
(Weed Science Society of America., 2011)
Solanum viarum, commonly known as tropical soda apple (TSA), is native to Brazil and Argentina but has become a harmful weed in many countries with tropical climates. This study was conducted to reassess the seed biology ...
Cadmium induces hypodermal periderm formation in the roots of the monocotyledonous medicinal plant Merwilla plumbea.
(Annals of Botany Company., 2010)
Background and Aims. Merwilla plumbea is an important African medicinal plant. As the plants grow in soils contaminated with metals from mining activities, the danger of human intoxication exists. An experiment with plants ...
Micropropagation and pharmacological evaluation of Boophone disticha.
Boophone disticha (L.f.) Herb is one of the most widely distributed bulbous species in southern Africa. Of Africa’s many bulbous plants, it is widely known for its poisonous and medicinal properties. It is of considerable ...
Stress related responses in soybean.
Environmental stresses such as drought, salinity and low temperature have been major selective forces throughout plant evolution and are important factors which limit crop plant distribution and agricultural productivity. ...
Alkaloids from three South African Crinum species.
The alkaloid content of three Crinum species namely C. bulbispermum, C. macowanii and C. moorei was investigated. The ethanolic extracts of C. bulbispermum yielded seven compounds. The new alkaloids 8α-ethoxyprecriwelline, ...
The effect of charcoal on tissue morphogenesis in vitro.
The effect of activated charcoal, autoclaving and culture media on sucrose hydrolysis in tissue culture media was investigated. Activated charcoal acidified an aqueous sucrose (5%) solution and culture media by about 1 ...
Breeding systems of some cold tolerant eucalyptus species.
Seasonal flowering times for Eucalyptus nitens, E. dunnii, E. smithii, E. macarthurii and E. grandis were evaluated in clonal grafted orchards located at the Shaw Research Centre (SRC) in KwaZulu-Natal, South Africa. ...
