Abstract: The common calluses derived from roots of Angelica sinensis were treated with phytohormones and different kinds of organic adjuvants with various concentrations to induce embryogenic callus. The phytohormones obviously affected embryogenic callus induction and the process of globular, heartshaped, torpedo and cotyledon stages. They could emerge from both inside and surface of calluses. In the developmental process, the embryoid still kept in contact with the base of callus from which it arose.

Key words: Angelica sinensis (Oliv.), Diels, Phytohormone, Embryogenic callus, Embryoid
