AbstractThe purpose of this study was to determine if the creosotebush contains an inhibitor which may be a contributing factor to the invasion of creosotebush on grassland. Aqueous extracts from creosotebush plant material, of relatively high concentration, significantly reduced the germination of black grama caryopses, prevented the development of radicles and significantly reduced plumule growth of both black grama and bush muhly. The extract was not inhibitory to germination or seedling growth of creosotebush.
