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... -
Relationship between DIMBOA content and atrazine tolerance in maize
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C. Malan --- , Republic of South Africa M.R. le Court de Billot --- , Republic of South AfricaData of two independent studies are presented to illustrate the relationship between DIMBOA content of maize inbreds and their tolerance to atrazine. Polynomial regression curves best described this relationship. R-squared values of 0,48 and 0,87 between DIMBOA content and tolerance...
