  1. The development of a leaf tensilmeter for <em>in situ</em> measurement of leaf tensile strength

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The development of a portable leaf tensilmeter for the in situ measurement of leaf tensile strength is described. Tensile strength is determined by the distortion of strain gauges on modified stripping pliers which are used to break leaf blades. The...
  2. Proximate composition of carob cultivars growing in South Africa

    Proximate composition of carob cultivars growing in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Five carob (Ceratonia siliqua L.) cultivars grown in South Africa were analysed for proximate and polyphenol composition as well as for mineral, amino and fatty acid content. Carob pods from the five cultivars were obtained from two locations in the...

    For both the lecturer and the student the operating of the microcomputer should not offer any problems. Seeing that programming takes a long time, authoring packages can be used. Authoring packages are not implemented in this study because of the...
  4. Gastric evacuation time and digestive enzyme activity in abalone <em>Haliotis midae</em> fed a formulated diet

    Gastric evacuation time and digestive enzyme activity in abalone <em>Haliotis midae</em> fed a formulated diet

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Gut evacuation time and enzyme activity were monitored over 46 h in juvenile Haliotis midae fed a formulated diet. Gut fullness peaked 6 h after feed was offered and returned to pre-feeding levels within 24 h. Enzyme secretion began with...

  6. The effect of age on the reproductive output of the abalone pest <em>Terebrasabella heterouncinata</em> (Polychaeta: Sabellidae: Sabellinae)

    The effect of age on the reproductive output of the abalone pest <em>Terebrasabella heterouncinata</em> (Polychaeta: Sabellidae: Sabellinae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    High levels of infestation by the polychaete Terebrasabella heterouncinata on cultured abalone may be attributed to elevated levels of fecundity in comparison with conspecifics in their natural habitat. It is not, however, known if a high reproductive output is sustained...
