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.
结果表明：辐照处理对种胚原球茎的生长和分化有抑制作用，尤其是对根的抑制更为明显；由于种胚原球茎的完整性好，耐受性强，其辐照半致死剂量(LD50)为67.23Gy；流式细胞分析表明，大多数外部形态发生改变的植株其细胞内DNA的倍性发生了改变，出现相当多的非整倍体；此外，辐照产生的变异苗出现茎分叉、叶片缺绿或白绿相间等现象，可能是由于某些基因的表达与关闭引起的。

protocorm：原球茎
通常先形成原球茎(Protocorm)随后再发育成一棵小植株. 原球茎是兰花较原始程度的非常幼小的芽,再生能力强,可切割分离不断增殖,从而形成大量遗传一致的材料. 采用分生组织繁殖的另一个优点是再生植株通常不含病毒.
