Abstract: The development of the embryo of Zizyphus jujuba Mill. conforms to the Asterad type. The transverse division of the zygote results in the formation of the terminal and basal cells. The basal cell of the two-celled proembryo divides transversely first and contributes to the suspensor and a minor part of the embryo proper in further development. The terminal cell first divides vertically and the divisions in various ways contribute to almost all parts of the embryo proper. The endosperm development is of the nuclear type. Three stages may be divided as follows: the free nuclear stage, the wall formation stage and the stage in which the disorganization of the endosperm cells takes place rapidly. The developments of the embryo and endosperm are well correlated. Thus the morphological development of the embryo may be used as an indicator to tell the development stage of the endosperm. The adequate stage for endosperm culture is in the wall formation stage.
