Stimulation of <i>Striga asiatica</i> (Witchweed) Seed Germination by 6-Substituted Purines

Abstract

Kinetin [6-(2-furfuryl) aminopurine] and certain other 6-substituted aminopurines stimulated germination of seed of Striga asiatica (L.) Kuntze. Optimum concentration for most active compounds was in the range of 5 to 25 mg/lit. Derivatives which showed high activity possessed an adenine nucleus with a phenyl, benzyl, phenethyl, or furfuryl radical substituted on the amino group.
