Abstract

Direct somatic embryogenesis was successfully achieved from immature leaves of cassava (Manihot esculenta Crantz) cultured on induction medium containing 2,4-dichlorophenoxyacetic acid or naphthaleneacetic acid. Changing the duration of induction or changing plant growth regulators resulted in differences in regeneration of somatic embryos or adventitious shoots. The results showed that auxin was a key factor for inducing embryogenic cells. The embryogenic cells were mainly induced within 4–12 days. Only if the embryogenic cells were induced, the auxin enhanced formation of somatic embryo whereas 6-benzylaminopurine stimulated development of adventitious shoots. Histological examinations supported the conclusion.
