Competition for light and space and allelopathy are well known factors responsible for the weed suppressive potential of cereals. During her studies, Antje Reiss focused on the identification of the relative contributions of competition and allelopathy to the overall weed suppressive effect of the winter cereals wheat, triticale and rye. In order to measure allelochemicals in the root zone, Antje Reiss developed a non-destructive sampling method called silicone tube microextraction for the recovery of phytotoxic compounds belonging to the group of benzoxazinoids. The new research findings form the precondition for the implementation of novel breeding programmes focusing on the development of cultivars with increased weed suppressiveness.

The PhD degree was completed at the Department of Agroecology, Crop Health, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
