(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 ... -
Crinum moorei : propagation and secondary metabolite production in vitro.
(2002)As an alternative to conventional methods of vegetative propagation, micropropagation attracts much attention, because the levels of multiplication are increased, somaclonal variation is limited and disease-free material ... -
Cultivation of Combretum bracteosum (Hochst.) Brandis.
(2001)In maximizing South Africa's floral diversity, plant propagators have begun exploiting the rich array of indigenous plants, especially those with horticultural potential. Plants previously unavailable to the professional ... -
Cytokinins and the germination of Tagetes minuta L.
(2003)Tagetes minuta L. is a weedy herb that has been a rich source of fragrant oils, used as in the perfume and flavour industry. T. minuta achenes germinate erratically under field conditions. However, at the optimal germination ... -
Differential gene expression in germinating and thermoinhibited achenes of Tagetes minuta L.
(2003)When imbibed at their optimum germination temperature of 25°C, achenes of Tagetes minuta L. germinate over a period of approximately 48 h. At temperatures of between 35°C and 39°C, the achenes do not germinate but enter ... -
The effect of charcoal on tissue morphogenesis in vitro.
(2000)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 ... -
