Screening for DIMBOA (benzoxazinone) concentration among South African inbred maize lines and sorghum cultivars
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C. Malan --- , J.H. Visser --- Department of Botany, H.A. van de Venter --- Department of Botany,Twenty-seven popular South African inbred maize lines, four commercial maize cultivars, two sweet corn cultivars and two grain sorghum cultivars were screened by means of a rapid, semi-quantitative method to determine DIMBOA concentration. Significant differences were found between inbred lines... -
Growth responses of inbred maize lines with high and low DIMBOA (benzoxazinone) contents to atrazine
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C. Malan --- , J.H. Visser --- Department of Botany, H.A. van de Venter --- Department of Botany,The growth response of five inbred maize lines with high and low DIMBOA content were compared in the presence of 3 and 12 ppm atrazine. A growth-promoting effect of atrazine on roots, mesocotyls and coleoptiles was observed in dark-grown seedlings... -
Qualitative estimation of atrazine, hydroxyatrazine and 6-methoxy-2-benzoxazinone (MBOA) in maize plants
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C. Malan --- , Republic of South Africa J.H. Visser --- Department of Botany, Republic of South Africa H.A. van de Venter --- Department of Botany, Republic of South AfricaA rapid and simple method for the extraction and quantification of the herbicide atrazine, the atrazine hydroxylating agent in maize plants DIMBOA, and the hydroxylated product hydroxy-atrazine, is described. These substances were quantified by means of HPLC techniques, employing a...
