The ability of scutellum to initiate callus decreased with the increase of embryo age. The scutellia of 3-week or more old embryos couldn't produce any callus but secrete alpha amylase, and absorb, transform, and transfer nutrients from the endosperm. Transfer cells were observed before the establishment of conducting system. The differentiation and formation of adventitious root and shoot could be from either organogenesis or embryoids. The formation sequence of root and shoot primordia were not consistent
