    Aspalathus and Podalyria legumes balance acquisition of phosphorus and nitrogen for growth in nutrient poor fynbos soils
    (2015) Maistry, Pravin Mark; Chimphango, Samson B M; Muasya, A Muthama; Valentine, Alex J
    Legume species nodulate and grow successfully in the Core Cape Subregion, a Mediterranean-climate ecosystem with fynbos vegetation found on infertile soils. The physiological mechanisms enabling tolerance of low availability of phosphorus (P) are yet to be reported in Cape legume species such as Aspalathus linearis and Podalyria calyptrata; species that demonstrated traits typical of plants from nutrient poor soils. In the three research chapters of the thesis, it was anticipated that low P supply would limit plant growth and increase expression of traits for P acquisition.

    Phosphorous requirement of indigenous N-fixing legumes and rhizobial diversity in the low P soils of the Cape floristic region, South Africa
    (2010) Maistry, Pravin Mark; Here, Text
    Soils of the Cape Floristic Region (CFR) vary in phosphorous (P) availability and legume species tend to be distributed in specific edaphic habitats. Eighteen indigenous CFR legume species were grouped as high-P, low-P, Pgeneralist and unclassified plants, by associating their distribution with soil [P] in the CFR. It was hypothesized that the low-P group would be superior N2-fixers than the high-P group at low P supply.
