Propagation of Coleonema album (Thunb.) Bartl. & J. C. Wendl. : a horticultural and medicinal plant.
Coleonema album is a South African green treasure, endemic to the Cape region and hard to find in other parts of the country. It is ranked among the most highly utilized medicinal plants at present. The plant extracts ...
Studies on factors influencing viability after cryopreservation of excised zygotic embryos from recalcitrant seeds of two amaryllid species.
Recalcitrant unlike orthodox seeds do not show a sharp border between maturation and germination and remain highly hydrated and desiccation-sensitive at all developmental and post-harvest stages. In contrast with ...
Polyamines in Ecklonia maxima and their effects on plant growth.
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® ...
In vitro studies and phytocompound analysis in Lessertia frutescens (Fabaceae)
The cancer bush (Lessertia frutescens L.) is an important leguminous perennial native to southern Africa and has been used for centuries in traditional medicine by the continent’s diverse cultural groups. Like many other ...
Physiological and molecular characterization of habituated and non- habituated soybean callus lines (Glycine max (L.) Merr cv. Acme)
A cytokinin habituated soybean callus has been isolated, utilizing the cytokinin soybean bioassay. The habituated callus line was subsequently characterized with a non-habituated callus line in relationship to levels ...
Seed dormancy and germination in Protea compacta R.Br. and Leucadendron daphnoides Meisn.
The germination responses of seed to a wide variety of treatments showed that both the pericarp and the embryo contribute to the dormant condition in Protea compacta. Germination can be improved to a greater or lesser ...
The morphology and chemical composition of the trichomes of Withania somnifera (Solanaceae)
For centuries, plants have been used in the cosmetic, culinary and medicinal industries. Recently however, the use of plants in the medicinal industry has increased due to the widespread awareness of the harmful effects ...
The use of growth kinetics in the development of a predictive model for the growth of Eichhornia crassipes (Mart.) Solms in the field.
Abstract available in PDF file.
Growth characteristics of three Eucalyptus clonal hybrids in response to drought stress : the underlying physiology.
Previous research by Drew et al. (2009) on a SAPPI dendrometer trial, in northern KwaZulu-Natal, South Africa, yielded growth results for two Eucalyptus grandis clones (termed E. grandis x urophylla (GU) and E. grandis x ...
Towards developing effective decontamination procedures for in vitro culture of embryonic axes excised from recalcitrant seeds.
Control of seed-associated micro-organisms is vital in reducing losses of plants of economic importance. Recalcitrant seeds being metabolically active and able to be stored only under conditions of high relative humidity ...
