Physiological and molecular characterization of habituated and non- habituated soybean callus lines (Glycine max (L.) Merr cv. Acme)
(1998)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 ... -
Physiological aspects of shoot growth regulation in juvenile and adult Citrus sinensis (L.) Osbeck.
(1982)As the requirements for more efficient and economical crop production emerge, so the need for a better understanding of plant growth and development is felt. It is especially the need to understand means by which man may ... -
The physiology of flowering with contributions by in vitro techniques.
(1987)Abstract cannot be copied from pdf document. -
The physiology of pinus patula seedlings in response to water stress and the implications for plantation regeneration in South Africa.
(2008)Pinus patula Schiede ex Schlect. & Cham. is the most widely planted softwood species for both pulpwood and saw timber in the South African forestry industry. High mortality of this species, often in excess of 20%, following ... -
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. ... -
A plant ecological survey of the Umfolozi Game Reserve, Zululand.
(1972)A landscape unit approach based on use of airphotos was used for investigation of Deciduous Acacia Woodland in the Reserve. The approach was useful for indicating that a quantity of as few as 531 samples could be suitable ... -
The plant ecology of seasonally flooded areas of the Pongolo River Floodplain, with particular reference to Cynodon dactylon (L.) Pers.
(1982)The impounding of the waters of the Pongolo river, upstream of its floodplain on the Mocambique coastal plain, may adversely affect the functioning of the floodplain system. A multidisciplinary study of the functioning ... -
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 ... -
Pollination and geographical divergence in flower colour of the drosera cistiflora species complex, or 'how the snotrosie got its colours'.
(2019)The question of floral colour diversity among congeneric plants has intrigued evolutionary biologists since Lamarck—yet remains a hot topic amid the varied groundbreaking ecological insights that emerge to this day. I ... -
Pollination of Plectranthus L'Her. (Lamiaceae) along the Eastern seaboard of southern Africa.
(2009)Pollination data is provided for a third of the Plectranthus species in southern Africa. In the largest genus of Lamiaceae in the region (53 species), 18 were studied, plus two species of allied genera (Pycnostachys ... -
Pollination, floral deception and evolutionary processes in Eulophia (Orchidaceae) and its allies.
(2009)Orchids provide a model system for addressing evolutionary and ecological questions both because of their species diversity, and because the packaging of their pollen into pollinia facilitates the estimation of male and ... -
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 bulk segregant analysis and RAPD technology for identification of molecular markers linked to traits in sugarcane.
(1998)The objective of the present study was to investigate the potential use of bulk segregant analysis (Michelmore et al., 1991) as a method to rapidly identify genetic markers linked to traits in sugarcane. Four bulked DNA ... -
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 ... -
Proline biosynthesis in transgenic soybean plants.
(2000)Plants have evolved numerous strategies for the adaptation to drought. Although many investigations reported on the potential value of proline accumulation during environmental stress, it is still unknown whether or not a ...
