The results indicated that the treatment of irradiation restrained the growth and differentiation of protocorm, especially to roots.The LD50 is 67.23Gy, because the protocorm is a integrate embryoids and higher tolerance was found. Ploidy analysis showed that most of aberrant seedlings go with the change of DNA and they were not euploid. When the plants trearted by irradiation, some of aberrant seedlings appeared stem forfication, and leaves appeared chlorophyll-deficient or green-white.,probably due to some genes' expression or closing.

endoderm:内皮层

中胚层细胞通过胚孔或原沟进入胚胎内部,沿着内皮层(endoderm)以阿米巴虫的方式向前延伸,并聚集在发育的前肠两边,形成两个分隔的团聚体. 两个团聚体形成双层管状物. 该管的内壁变成内心膜,外壁变成肌肉性的心肌. 当内胚层具备前肠沟的形式时,

primitive endoderm:原始内胚层
