[Wheat androgenic embryoids and calli: data of scanning electron microscopy]

The surface of wheat androgenic embryoids and calli at different developmental stages was studied using SEM. The embryoids were already characterized by regular cell divisions at the early developmental stages, while the calli were represented by irregular cell conglomerates. This trend was preserved during further development of androgenic structures. SEM studies of the surface of so-called secondary embryoids confirmed these observations.
