Abstract: It is important to study somatic embryogenesis in vitro for the yielding of garlic, which is mainly propagated by vegetations. The paper described the different factors affecting on garlic embryogenesis. It might be enhanced by a higher concentration of Vitamin B1 and reductive nitrogen, but inhibited by endotoxin of cell. Another, the problems in this area had been discussed, and it was necessary to study on cellular and molecular biological mechanism of embryogenesis, set up suspension culturing system and investigate the variant of somatic embryoes.
