Bepaling van die fisiologiese gesondheid van akkerbome (Quercus robur) in Potchefstroom
(North-West University (South Africa), 2022)Trees in an urban setting, such as the exotic Oak trees (Quercus robur L.) in Potchefstroom (North West province, South Africa), provide several ecosystem services on individual tree, street and city level. Since urban ... -
Effect of glyphosate applications on growth responses of various glyphosate tolerant maize hybrids
(North-West University (South Africa), Potchefstroom Campus, 2016)Glyphosate is a highly effective non-selective, broad-spectrum, post-emergence herbicide used to control a broad spectrum of grasses and broad-leaf weeds. Glyphosate was initially largely used as a burn-down herbicide to ... -
Effects of the invasive annual grass Lolium multiflorum Lam. on the growth and physiology of a Southern African Mediterranean-climate geophyte Tritonia crocata (L.) Ker. Gawl. under different resource conditions
(North-West University, 2007)Little is known of the physiological and biochemical mechanisms underlying competitive interactions between alien invasive grasses and native taxa, and how these are affected by resource supply. Consequently, this study ... -
The impact of different industrial related abiotic stresses on maize photosynthesis
(North-West University (South Africa), Potchefstroom Campus, 2015)During the past few decades, a sharp rise in industrial activity in the mineral rich Highveld region of South Africa has been seen. Together with this increase in industrial activity, an accompanying increase in urbanization ... -
Limitation of photosynthetic carbon metabolism in South African soybean genotypes in response to low night temperatures
(North-West University, 2008)Soybean (Glycine max (L.) Merr.) is a key source of protein for humans and animals, but is unfortunately chilling sensitive. A single episode of low night temperature (dark chilling) is sufficient to inhibit pod formation ... -
Physiological response of the succulent Augea capensis (Zygophyllaceae) of the southern Namib desert to SO2 and drought stress
(North-West University, 2006)The main aim of this study was to investigate the effects of water availability and SO2 pollution, imposed separately or simultaneously, on the photosynthetic metabolism of Augea capensis Thunb., a succulent of the Namib ...
