胚状体是植物组织培养中起源于一个非合子细胞,经过胚胎发生和发育过程形成的胚状结构。它具有分化频率高、繁殖速度快的特点。自1958年 Steward 等人用胡萝卜细胞悬浮培养获得胚状体以来,在国际上引起了广泛的注意。近20年,用离体培养方法已经在34科、75属、117种植物中诱导产生了胚状体。1978年我国广西柳城甘蔗研究所又从单子叶植物甘蔗的体细胞中,诱导产生了胚性细胞团,它能连续继代增殖胚状体。但在 Embryoid bodies are embryoid-like structures that originate from a non-zygotic cell in plant tissue culture and are formed during embryogenesis and development. It has a high frequency of differentiation, breeding speed characteristics. Since Steward et al. Obtained the embryoid body by carrot cell suspension culture in 1958, it has attracted a great deal of attention in the world. In the last 20 years, embryoid bodies have been induced in 34 families, 75 genera and 117 species using in vitro culture methods. In 1978, Guangxi Liucheng Sugarcane Research Institute induced the generation of embryogenic cell mass from the somatic cells of monocotyledon sugarcane, which could continuously subculture and proliferate embryoid body. But in
