The use of acid Polyacrylamide gel electrophoresis to determine the effect of locality of growth on the protein profiles of barley, wheat and honeybush tea

Autor: O. T. de Villiers, M. Bosman

Publikováno v: South African Journal of Plant and Soil. 14:131-136

Acid Polyacrylamide gel electrophoresis (A-PAGE) of proteins was used to identify different spring wheat cultivare, barley cultivars and Cyclopia species. Experimental conditions for the extraction of the proteins from single kernels as well as corre

Identification of Cyclopia species (‘Heuningbostee’) using Polyacrylamide gel electrophoresis

Autor: J H De Lange, O. T. de Villiers, M. Bosman

Publikováno v: South African Journal of Plant and Soil. 14:54-57

Protein banding patterns of seed obtained by sodium dodecyl sulphate Polyacrylamide get electrophoresis (SDS-PAGE) or acid polycrylamide gel electrophoresis (A-PAGE) were used to distinguish between different Cyclopia species (‘heuningbostee’). A

Evaluation of proline accumulation as an indicator of drought tolerance in spring wheat cultivars

Autor: P. D. R. Van Heerden, O. T. de Villiers

Publikováno v: South African Journal of Plant and Soil. 13:17-21

The aim of this study was to evaluate proline accumulation as an indicator of drought stress and drought tolerance in spring wheat cultivars (Triticum aestivum L.) grown in the Western Cape. Drought stress was induced in whole plants and leaf discs i

Analysis of the HMW glutenin subunit composition of wheat cultivare by SDS-PAGE

Autor: M. Bosman, O. T. de Villiers

Publikováno v: South African Journal of Plant and Soil. 13:1-4

The composition of the high-molecular weight (HMW) glutenin subunits of 13 wheat cultivars grown in the Western Cape was determined using Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate (SDS-PAGE). The molecular weight o

Extraction and electrophoretic separation of proteins from leaves of scions and rootstocks of Vitis cultivars

Autor: E W Le Grange, O. T. de Villiers

Publikováno v: South African Journal of Plant and Soil. 13:42-46

Proteins were extracted and separated by SDS-PAGE from leaves of scions and rootstocks of different Vitis cultivars. Banding patterns were used to identify the different cultivars after extraction of the proteins with a medium containing Tris-HCI (0.

Quality response of spring wheat cultivars to post-anthesis water stress intensity

Autor: O. T. de Villiers, G. A. Agenbag

Publikováno v: South African Journal of Plant and Soil. 12:45-49

The effect of different intensities of water stress imposed during the first three weeks of grain filling were determined on the protein content, protein composition and bread volume of three spring wheat cultivars. Water stress was induced by wateri

Physiological response of spring wheat cultivars to post-anthesis water stress intensity

Autor: O. T. de Villiers, G. A. Agenbag

Publikováno v: South African Journal of Plant and Soil. 12:27-31

Wheat crops produced under dryland conditions in the winter rainfall belt of South Africa are often subjected to water stress. To study the effect of water stress on the spring wheat cultivars Nantes, Palmiet and SST 66, an experiment was conducted i
