Traditional paraffin sectioning method,iron alumhaematoxylin hematoxylin and PAS method were utilized in order to observe the embryo and endosperm development of Ceratoides.arborescens.The results indicated that the embryo development of Ceratoides.arborescens was the Chenopodiad type;the zygote formed a liner four cells proembryo and similar T type four cells proembryo;the style of endosperm development was the Nuclear type.Abnormal development phenomenon is observed in later globular embryo,normal divisions was not undergene,the embryo grew at elliptoid.The nutrition of embryo development came from the amylose of nucellus tissue,endosperm and so on.Taking the nutrition supplyment into account,it can be concluded that abnormal embryo was not caused by insufficient nutrition.This phenomenon may be one reason of embryo abortion in Ceratoides.arborescens.
