Lizeth Swart Thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Agriculture at the University of Stellenbosch Supervisor: Prof. P. W. Crous Decem ber 1999 Stellenbosch University https://scholar.sun.ac.za DECLARATION 1, the undersigned, hereby declare that the work contained in this thesis is my own original work and has not previously in its entirety or in part been submitted at any university for a degree. SIGNATURE: DATE: Stellenbosch University https://scholar.sun.ac.za PATHOGENS ASSOCIATED WITH DISEASES OF PROTEA, LEUCOSPERMUM ANDLEUCADENDRONSPP. SUMMARY The manuscript consists of six chapters that represent research on different diseases and records of new diseases of the Proteaceae world-wide. The fungal descriptions presented in this thesis are not effectively published, and will thus be formally published elsewhere in scientific journals. Chapter one is a review that gives a detailed description of the major fungal pathogens of the genera Protea, Leucospermum and Leucadendron, as reported up to 1996. The pathogens are grouped according to the diseases they cause on roots, leaves, stems and flowers, as well as the canker causing fungi. In chapter two, several new fungi occurring on leaves of Pro tea, Leucospermum, Telopea and Brabejum collected from South Africa, Australia or New Zealand are described. The following fungi are described: Cladophialophora proteae, Coniolhyrium nitidae, Coniothyrium proteae, Coniolhyrium leucospermi,Harknessia leucospermi, Septoria prolearum and Mycosphaerella telopeae spp. nov. Furthermore, two Phylloslicla spp., telopeae and owaniana are also redecribed. The taxonomy of the Eisinoe spp.

SOME FACTORS INFLUENCING THE SUDDEN DEATH SYNDROME IN CUT FLOWER PLANTS A thesis presented in partial fulfilment of the requirements for the degree of Master of Horti cultural Science at Massey University Clinton N Bowyer 1996 11 ABSTRACT Soil/root mixes from plants with the Sudden Collapse Syndrome of cut flower plants were tested for Phytophthora infection using a lupin (Lupinus angustifolius) baiting technique. Boronia heterophylla and Leucadendron 'Wilsons Wonder' root samples both caused the lupin seedlings to exhibit symptoms of Phytophthora infection. The efficacy of phosphorous acid (Foschek® 500 at 1000 ppm and 2000 ppm) and a combination of phosphorous acid and an additional product (Foschek® 500 and C408 at 1000/200 ppm and 2000/400 ppm) in controlling Phytophthora cinnamomi root infections of L 'W ilsons Wonder', B.heterophylla and B. megastigma rooted cuttings was compared with fosetyl­ AI (Aliette® 80 SP at 1000 ppm and 2000 ppm) under conditions of high disease pressure. The fungicides were applied as a root drench 7 days prior to the roots being inoculated by a split wheat technique and the effect of the fungicides and their concentrations on the rate of plant mortality was measured. The results were species dependent.

  • The Functional Role of Birds As Pollinators in Southern Cape Fynbos
    The functional role of birds as pollinators in southern Cape fynbos. Kellyn J. Whitehead A thesis presented in fulfilment of the academic requirements for the degree of Masters of Science in Ecological Sciences At the University of KwaZulu-Natal, Pietermaritzburg, South Africa January 2018 1 ABSTRACT Nectarivorous birds, particularly sunbirds, are important pollinators of plants in the Cape Flora of South Africa, being responsible for pollinating approximately 5% of plant species. However, interactions between plants and nectarivorous birds in the eastern part of the Cape Floristic Region have not received much attention. This study focussed on two putatively bird-pollinated plant species found within the Nature’s Valley area, namely Kniphofia uvaria and Chasmanthe aethiopica. The breeding systems were determined for each species and, due to their patchy population distribution, potential Allee effects on plant fecundity were also tested for. Flowering phenology in the area was also examined to test for associations between flowering of bird-pollinated plant species and the temporal presence of nectarivorous birds. Selective exclusion experiments showed that sunbirds were the main pollinators of K. uvaria and C. aethiopica – fruit set and the number of viable seeds were much higher for untreated (open control) individuals where birds could visit flowers freely, compared to caged individuals which only allowed for insect visitation. Very few seeds developed when plants of the two species were bagged to exclude all pollinators, indicating that the species are not capable of autonomous self-fertilization. Fruit and seed set were determined for patches of K. uvaria and C. aethiopica in order to test for potential Allee effects.

  • Kirstenbosch NBG List of Plants That Provide Food for Honey Bees
    Indigenous South African Plants that Provide Food for Honey Bees Honey bees feed on nectar (carbohydrates) and pollen (protein) from a wide variety of flowering plants. While the honey bee forages for nectar and pollen, it transfers pollen from one flower to another, providing the service of pollination, which allows the plant to reproduce. However, bees don’t pollinate all flowers that they visit. This list is based on observations of bees visiting flowers in Kirstenbosch National Botanical Garden, and on a variety of references, in particular the following: Plant of the Week articles on www.PlantZAfrica.com Johannsmeier, M.F. 2005. Beeplants of the South-Western Cape, Nectar and pollen sources of honeybees (revised and expanded). Plant Protection Research Institute Handbook No. 17.

  • The Potential of South African Indigenous Plants for the International Cut flower Trade ⁎ E.Y
    Available online at www.sciencedirect.com South African Journal of Botany 77 (2011) 934–946 www.elsevier.com/locate/sajb The potential of South African indigenous plants for the international cut flower trade ⁎ E.Y. Reinten a, J.H. Coetzee b, B.-E. van Wyk c, a Department of Agronomy, Stellenbosch University, Private Bag, Matieland 7606, South Africa b P.O. Box 2086, Dennesig 7601, South Africa c Department of Botany and Plant Biotechnology, University of Johannesburg, P.O. Box 524, Auckland Park 2006, South Africa Abstract A broad review is presented of recent developments in the commercialization of southern Africa indigenous flora for the cut flower trade, in- cluding potted flowers and foliages (“greens”). The botany, horticultural traits and potential for commercialization of several indigenous plants have been reported in several publications. The contribution of species indigenous and/or endemic to southern Africa in the development of cut flower crop plants is widely acknowledged. These include what is known in the trade as gladiolus, freesia, gerbera, ornithogalum, clivia, agapan- thus, strelitzia, plumbago and protea. Despite the wealth of South African flower bulb species, relatively few have become commercially important in the international bulb industry. Trade figures on the international markets also reflect the importance of a few species of southern African origin. The development of new research tools are contributing to the commercialization of South African plants, although propagation, cultivation and post-harvest handling need to be improved. A list of commercially relevant southern African cut flowers (including those used for fresh flowers, dried flowers, foliage and potted flowers) is presented, together with a subjective evaluation of several genera and species with perceived potential for the development of new crops for the florist trade.
