Abstract

Seeds of Striga asiatica (L.) Kuntze were induced to germinate with a stimulant from host exudates in the presence of a water-soluble germination inhibitor extracted from Striga seeds. Germination obtained was dependent upon the relative concentrations of stimulant and inhibitor present in the germination medium. The inhibitor had no effect on radical elongation of Striga seeds that germinated in its presence.
