Dehulling and Seed Germination in Vernonia Anthelmintica (L.) Willd.1

Abstract

Abstract

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.
