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。

结果表明，最适合长白舌唇兰原球茎和类原球茎诱导的培养基为N6+TDZ0.05mgL^(-1)+NAA0.01 mgL^(-1)+KT0.50 mgL^(-1)，诱导率为92.5%；最适合凹舌兰原球茎和类原球茎诱导的培养基为N6+TDZ0.05 mgL^(-1)+KT0.50 mgL^(-1)，诱导率为98%；长白舌唇兰类原球茎萌发为完整植株的最佳培养基为N6+IAA0.01 mgL^(-1)，萌发率为96%；凹舌兰类原球茎萌发为完整植株的最佳培养基为N6+IAA0.01 mgL^(-1)+GA30.01 mgL^(-1)，萌发率为94.5%。

The dry seeds of Dendrobium nobile and Pleione maculata were cultured on MS, B5 and KC liquid media for inducing protocorms, and the protocorms were subcultured on MS, KC and B5 solid media to study the growth of protocorm differentiation seedlings in the different medium.

方法］将石斛兰和秋花独蒜兰的干种子培养于MS、B5、KC液体培养基上，诱导原球茎形成，再将原球茎培养于MS、KC及B5固体培养基中，研究原球茎分化苗在不同培养基上的生长发育情况。

The increment of 6-BA concentration can increase the protocorm propagation obviously. And the matching of high concentration of 6-BA and low concentration of NAA is more suitable for the protocorm propagation of C. grandiflorium. 6-BA at the concentration of 1.5 mg/L was most favorable for protocorm induction and differentiation.

结论］6-BA浓度的增加，可明显提高原球茎的增殖，高浓度6-BA与低浓度NAA的配比较适合大花蕙兰的原球茎增增殖；6-BA在1.5 mg/L时最有利于原球茎的诱导分化。

The phenomenon of vitrification could restore significantly after culture 2 or 3 generations in the culture medium without hormone. The differentiation ability of protocorm restored and the state of plant growth was consistent with the formal protocorm. It could continue applying to the manufacture of tissue culture.

玻璃化类原球茎在无植物生长调节剂培养基中经2~3代恢复培养后，数量下降到0.84%，玻璃化现象可得到明显恢复，恢复后的类原球茎的分化能力和植株生长状态与正常类原球茎一致，无变异现象发生，可继续应用于组培生产。

Oncidium on 15 hrs light period and night break treatments exhibited heavier fresh and dry weights, lower total soluble sugar content in pseudobulb because nutrient translocated for inflorescence development, however water content was no significantly different. After treatment of 9 hrs and 12 hrs light period, the total soluble sugar content in pseudobulb of Oncidium was higher than other treatments because of consuming less nutrient transfered from pseudobulb due to poor inflorescence development and the quality of inflorescence also showed worse.

以15小时电照周期处理与暗期中断处理之植株乾鲜重较重，含水量则无明显差异，而假球茎内的全可溶性糖含量则较其他处理组低，因为花序发育时，假球茎内的碳水化合物转移到花序，以提供花序发育所需之养分。9小时电照周期处理组与12小时电照周期处理组方面，因为其花序品质较差，消耗的养分较少，故其假球茎内的全可溶性糖含量较高。

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.
