OBSERVATIONS ON MORPHOLOGY AND CYTOLOGY OF EMBRYOIDS DERIVED FROM CALLUS OF MAIZE

Kuo Chung-shen Lu Wen-liang (Institute of Botany,Academia Sinica)  
Observations on the callus sections showed that most embryoids were pro- duced from surface layer cells of the callus and a few embryoids from inside layers of the callus.The initial cell of the embryoids possessed denser protoplasm and larger nucleus than the others cells did.The developmental sequence of the initial cell was similar to that of the zygotic embryos.First division gave rise to two daughter cells,the basal cell and termi- nal cell.The basal cell was able to divide or not divide again and changed into the suspen- sor,The terminal cell first divided longitudinally and then transversely into four cells.As the four cells further divided the embryo was formed properly.The embryoids possessed mono-,di-or polycotyledons.The production of the embryoids from a callus was not syn- chronous.So embryoids of different development stages could be found on the same callus.
