摘　　要：对水稻Ｃ１００１成熟种子进行形态解剖观察和各发育时期胚珠细胞胚胎学观察。获得以下结果：Ｃ１００ｌＡ×Ｃ１００１Ｂ的杂种后代种子中存在低频率的双胚。珠心细胞形成的不定胚是水稻Ｃ１００１的主要无融合生殖类型，另一可能来源是反足细胞。Ｃ１００１的小花中还存在多子房现象。去雄套袋隔离膨大的子房中，有的干瘪，有的饱满，里面充满液体空腔，少数真正结实。Anatomical observations and embryological studies were conducted for rice material C1001.The results showed that twin-embryos existed at a very low frequency in hybrid caryopse of C100lA×C1001 B.The major type of apomixis in rice C1001 is adventitious embryo which originated from nucellar cell.Its apomixis may originate from antipodal cell.Multiovary exist in a single flower.Most of the expanded ovaries after emasculation and isolation gradually shriveled or became empty.Only few could set seed.
