| 摘 要： | The processes about pollination, fertilization and embryo development of Chinese Date ‘Wu-he-zao‘ (ziziphus jujuba) were observed by means of lightmicrocope combining histochemical dyeing and fluorescent technique. The results were summarized as follows:The pollen grains germinated on the stigma at the 4th hour after pollination. On the 5th day after pollination,the primary endosperm nucleus formed, and the zygote formed on the 6th day. The double fertilization of Wu-he-zao was the type premitotic syngamy. The first division of the zygote took place after a dormancy for about 6 - 7 days. The proembryonal development of Wu-he-zao belonged to the Solanad type. The development of the endosperm belonged to the nuclear type.
