The performance and rooting of eucalyptus grandis x nitens cuttings.
(2007)Hybrid clones of Eucalyptus grandis and E. nitens (GN) have consistently been shown to be suitable for planting in cold, dry, marginal plantation sites, where they exhibit high yields and superior pulp properties. However, ... -
Pharmacological activities of selected South African medicinal plants.
(2011)The use of traditional medicine is a popular practice in South Africa especially among rural dwellers due to several reasons such as availability of natural products, cultural beliefs, preference of natural products to ... -
Pharmacology and phytochemistry of South African plants used as anthelmintics.
(2009)Traditional medicine in South Africa is part of the culture of the people and has been in existence for a long-time. Although animal components form part of the ingredients used, plant material constitutes the major ... -
Pharmacology and phytochemistry of South African traditional medicinal plants used as antimicrobials.
(2009)Among all the major infectious human diseases, gastro-intestinal infections caused by microbial pathogens are a major cause of morbidity and infant death in developing countries, largely due to inadequate sewage disposal ... -
Phytochemical and pharmacological investigations of invasive Chromolaena odorata (L.) R.M. King & H. Rob. (Asteraceae).
(2015)Chromolaena odorata (L.) R.M. King & H. Rob. (Asteraceae) is an invasive weedy scrambling perennial shrub native to the Americas that has proven to be a significant threat to both natural and semi-natural ecosystems as ... -
Phytosociology of the Namib Desert Park, South West Africa.
(1976)The geology, topography, soils and climate of the Namib Desert Park south of 23 S. Lat. are described briefly. The vegetation was investigated using the techniques of the Zurich - Montpellier school of phytosociology. ... -
Plant growth regulators and somaclonal variation in Cavendish banana (Musa AAA cv. Zelig)
(2004)Cavendish bananas are the most important sub-group of all bananas. They includes more than 30% of the global banana production and almost all bananas exported are of the Cavendish type. This sub-group is also an important ... -
Pollination and breeding systems of alien invasive plants in KwaZulu - Natal in South Africa.
(2001)According to Baker (1955), success of plant invasions can be attributed to autogamous breeding systems and generalist pollination systems. A test of Baker's rule was carried out on 19 invasive alien plant species in ... -
Pollination and evolution of the genus Mystacidium (Orchidaceae)
(2002)The morphology, anatomy and pollination biology of Mystacidium Lindl., a small, epiphytic genus of orchids, was investigated within a phylogenetic context. Morphological and anatomical studies were carried out in order ... -
Polyamines in Ecklonia maxima and their effects on plant growth.
(2012)Kelpak®, a seaweed concentrate (SWC) prepared from the brown seaweed Ecklonia maxima (Osbeck) Papenfuss, improves overall plant mass and fruit yield in a variety of crops. The main active principals isolated from Kelpak® ... -
The potential of hot water treatments for curtailing seed-associated mycoflora.
(1995)The consequences of toxigenic fungi associated with stored seed have stimulated these investigations aimed at developing treatments to minimise this mycoflora, without significantly reducing seed quality or viability. ... -
The potential use of sugarcane varieties for the identification of genetic markers.
(1996)The use of genetic markers that are linked to specific traits in sugarcane has the potential to increase the efficiency of the selection of improved varieties. Conventionally, markers are identified by analysing the ... -
Production and physiological responses of Italian ryegrass and white clover grown in mono cultures and mixed stands.
(1993)The aim of this study was to test the hypothesis that ryegrass and clover, when grown under optimal conditions in mixed stands, interact in response to available light energy. with other resources non-limiting, pasture ... -
