Fresh seed of four Vernonia anthelmintica (L.) Willd. selections were ( 1 ) untreated (N), ( 2 ) water soaked overnight (S), ( 3 ) soaked overnight followed by removal of pericarp (SP), or ( 4 ) soaked overnight followed by removal of pericarp and seedcoat (SPS). The SP treatment increased germination, but many abnormal seedlings resulted, probably due to seedcoat damage during dehulling. A considerable increase in germination followed the SPS treatment. Average shoot length of resulting seedlings approached that of the few normal seedlings after N and S treatments. The factor(s) inhibitory to the germination of fresh vernonia seed is associated with the seedcoat.
