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 ... -
The effect of elevated glutathione reductase and superoxide dismutase activities in stressed transgenic tobacco.
(1996)Life as we know it would be impossible in the absence of oxygen. However, too much oxygen can be toxic to the aerobic organisms which depend on it for their very existence. This apparent paradox arises as a result of ... -
The effect of H2O2 on the photosynthetic biochemistry of Pisum sativum.
(1990)To study the short-term effect of hydrogen peroxide on plant metabolism aminotriazole (2 mM), a catalase inhibitor was applied through the transpiration stream of pea seedlings and the gas exchange characteristics, ... -
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 ... -
Studies of transgenic tobacco plants containing Escherichia Coli glutathione reductase.
(1996)Glutathione reductase (GR) and superoxide dismutase (SOD) enzymes are thought to play an important role in the plant chloroplast antioxidant system. Tobacco plants transformed with E. coli glutathione reductase and ... -
The use of a virtual world to address misconceptions held by students regarding photosynthesis and respiration.
(1998)In an effort to contribute to the improvement of Matric Biology education, a survey was conducted in 1996 and 1997 of Matric pupils and first year students at several tertiary institutions, in order to identify those topics ...
