摘要：
The formation of globular, heart‐shaped and torpedo‐shaped embryoids was initiated in a cell suspension culture of differentiating celery callus. Sections of these embryoids were examined for cell differentiation. Sections were also taken from plantlets, seedlings and mature plants. No cell differentiation was seen in the globular and heart‐shaped stages but cell differentiation and tissue organization were present at the torpedo stage. The structure of the plantlet was simpler than that of the seedling but this may have been due to the conditions in the culture flask. Both plantlet and seedling leaf showed comparable levels of organization. It is concluded that biochemical development in the embryoid may be related to the onset of cell differentiation.
