Application of Partial Least Squares regression to relate tastiness of boiled potatoes to chemical and physical tests
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Marie F. Smith --- , South Africa Christine S. Leighton --- , South Africa Liesl Morey --- , South Africa Hettie C. Schönfeldt --- , South AfricaPartial Least Squares regression (PLS) was used to understand the relationship between 15 sensory attributes of potatoes boiled in their skins as dependent variables (Y), and six objective (chemical and physical) measurements as the independent variables (X). The ARC-Sensory Analysis... -
Ecology of diplostomid (Trematoda: Digenea) infection in freshwater fish in southern Africa
Item type: Journal Article • Journal: African Zoology • Authors: Andri Grobbelaar --- Department Zoology and Entomology, South Africa Liesl L. Van As --- Department Zoology and Entomology, South Africa Hennie J.B. Butler --- Department Zoology and Entomology, South Africa Jo G. Van As --- Department Zoology and Entomology, South AfricaThe complex life cycles of most trematode parasites include three hosts. The first intermediate host is a snail, the second is normally a teleost fish and a piscivorous bird serves as the definitive host. Lymnaeid snails are most likely to... -
Pathology of eyes and brain of fish infected with diplostomids, southern Africa
Item type: Journal Article • Journal: African Zoology • Authors: Andri Grobbelaar --- Department Zoology and Entomology, University of the Free State, South Africa Liesl L van As --- Department Zoology and Entomology, University of the Free State, South Africa Jo G van As --- Department Zoology and Entomology, University of the Free State, South Africa Hennie JB Butler --- Department Zoology and Entomology, University of the Free State, South AfricaOnly a few reports exist on diplostomid metacercariae found in southern African fish and even less information is available on the pathology associated with these infections. During surveys conducted in December 2008 and August 2010, different fish species were collected... -
Propagation of Hypoxis hemerocallidea by inducing corm buds
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Motiki M Mofokeng --- Agricultural Research Council–Roodeplaat, Vegetable and Ornamental Plants, South Africa Riana Kleynhans --- Department of Horticulture, South Africa Lesego M Sediane --- Agricultural Research Council–Roodeplaat, Vegetable and Ornamental Plants, South Africa Liesl Morey --- Agricultural Research Council–Biometry, Corporate Office, South Africa Hintsa T Araya --- Agricultural Research Council–Roodeplaat, Vegetable and Ornamental Plants, South AfricaAfrican potato is facing rapid decline of wild populations due to large-scale harvesting, necessitating efficient means of propagation. Propagation of African potato is difficult due to seed dormancy and the species does not naturally propagate easily from corms. This study... -
Hierarchical ranking of Urochloa mosambicensis (Bushveld herringbone grass) and Urochloa panicoides (Herringbone grass) competitiveness in four soil environments
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Maryke Craven --- Agricultural Research Council–Grain Crops, South Africa Patrick T Mokoena --- Agricultural Research Council–Grain Crops, South Africa Marlene M van der Walt --- Agricultural Research Council–Grain Crops, South Africa Liesl Morey --- Agricultural Research Council–Biometry, South Africa Anna EJ Saayman du Toit --- Agricultural Research Council–Grain Crops, South AfricaKnowledge of the competitive ability of weeds provide a better understanding of the requirements for weed control. The competitive ability of Urochloa mosambicensis (Hack.) Dandy. (Bushveld herringbone grass) and U. panicoides P. Beauv. (Herringbone grass) was investigated during 2017/18 in... -
Soil carbon stock assessment using depth and spatial models on afforested arable lands
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Trevan Flynn --- , Czech Republic Liesl Wiese --- , South Africa Andrei Rozanov --- , South AfricaThe change from grasslands and natural shrubs to afforested arable land has a major impact on soil organic carbon (SOC) stocks. Grasslands are known to be SOC sinks as seen in the Chernozems of North America, Eurasia and South Africa... -
