Abstract: Based on scanning electron microscopic observation,the surface feature of embryogeny process and the morphology of the various components that make up the embryo were described(Fig.1, Fig.3—3,5). The chaotic naming of the various components of the rice embryo was reviewed and checked. Thus, the wrong description of rice embryo morphology was found, for example,Juliano considered coleoptile or lateral-scale as epiblast(Fig.4-4, Fig.6-1); Yung and Kiyochika mistook the lateral scale as ventral scale(Fig.4-2); and in two Chinese translation books of Japanese the lateral scale was mistaken as coleoptile(Fig.4-1); etc. In this paper a new revised scheme of the structure of rice embryo and the naming of its structural components was proposed(Fig.7).

Key words: Oryza sativa, Embryo, Morphology

摘要： 本文根据扫描电镜观察,时稻胚发生过程及胚表面构件的形态作了描述,并对文献中存在的稻胚结构构件名称的混乱情况进行了查核。从而发现历来稻胚形态描述上与事实不符之处,如广为流传的 Juliano 论文中的图将胚芽鞘和侧鳞误以为外胚叶;容启东、星川清亲等将侧鳞误为腹鳞;《水稻的生长发育》和《稻的生长》等的中译本,则将侧鳞误为胚芽鞘等等。本文还提出了胚的结构及各构件的合理命名。
