The purpose of this study was to establish an efficient and stable gene transfer system for Phalaenopsis via pollen tube pathway. For this purpose, the growth and development of ovary and megaspore mother cell in Phalaenopsis was microscopically examined.

本研究主要是以花粉管法进行蝴蝶兰之基因转殖，希望建立效率高且稳定的转殖系统，以应用於蝴蝶兰育种。

The development of anther and ovule followed the finish of the flower organ initiation. Pollen mother cells and well developed microsporagium wall occurred when the diameter of the bud reached about 3.0 mm, and the archesporial cell which played the role of megaspore mother cell formed in ovule when the diameter of the bud reached about 3.5 mm.

花药及胚珠的发育与花器官的形态发生之间有明显的连续性，当花蕾直径为3.0 mm左右时花粉母细胞及完整的花粉囊壁形成，直径达到3.5 mm左右时胚珠中出现孢原细胞的分化，它直接起大孢子母细胞的功能。

In first stage,from the beginning of pollination to megaspore tetrad,pollen tubes grow axially,passing through gynostemium to the ovary and from proximal placenta along ovary wall develop upward.

花粉在柱头上萌发和生长后，花粉管沿着花柱一直延伸到子房，进入胚囊释放精细胞，实现精卵结合，这就是亲和受精过程[1]。

Meiosis of pollen mother cells of t he mutant and its receptor(line 814527) were observed.

对该不育变异体和受体花粉母细胞减数分裂过程进行观察。

Meiosis of pollen mother cells of the mutant and its receptor(line 814527) were observed.

对该不育变异体和受体花粉母细胞减数分裂过程进行观察。
