Differential responses of resistant and susceptible groundnut genotypes at cellular level to Ditylenchus africanus
Jordaan, Anine; Steenkamp, Sonia; McDonald, Alexander Henrique; De Waele, Dirk Gaby Marthe Albert (Brill Academy Publishers, 2011)Ditylenchus africanus causes cellular breakdown in pod tissue of susceptible groundnut cultivars. The histopathology of this nematode on a resistant genotype was studied using light microscopy and compared with the ... -
Host suitability of selected South African maize genotypes to the root-knot nematode species Meloidogyne incognita race 2 and Meloidogynejavanica: a preliminary study
Fourie, Hendrika; Ngobeni, G.L.; McDonald, Alexander Henrique; Mashela, P.W. (Scientific Publishing (NISC), 2011)Thirty-one commercial maize (Zea mays L.) hybrids and open-pollinated varieties (OPV's) were screened in separate greenhouse trials with a resistant inbred line MP712W as reference genotype for host suitability to Meloidogyne ... -

Sampling variation in the quantification of fumonisins in maize samples
Janse van Rensburg, B.; Flett, B.C.; McLarren, N.W.; McDonald, Alexander Henrique (Scientific Publishing (NISC), 2011)Fumonisins produced by F. verticillioides and F. proliferatum cause mycotoxicoses in horses, swine and rats and have been associated with oesophageal cancer in humans. Accurate measurement of mycotoxins is essential for ...
