Abstract：A somatic embryogenesis exprimental system derived from the callus of young inflorescence of Digitaria sanguinalis(L) Scop. has been established in Vitro. A prresumed sequence of developmental stages from the callus to somstic embryos at globular stage,pearshaped stage,cotyledon differentiation stage, plumular sheath differentiation stage and mature stage was observed. And heart-shaped embryo that is unique to dicotyledon was also found. This offers an embryological evidence to the origin of the monocot from the dicotyledon.
