中文摘要
本研究利用液體培養中的體胚發生，進行新鐵砲百合(Lilium formolongi hort.)大量繁殖。新鐵砲百合”諾利庫拉”品種由試管內實生苗鱗片，扦插於含0.1 mg/l NAA、90 g/l Sucorse的MS培養基，誘導癒合組織。癒合組織細胞液體培養的最適條件為，細胞接種量為3.0 g/20 ml，培養於含0.1 mg/l NAAmg/l與Sucorse 30 g/l的MS培養基，每培養四週細胞鮮重可以倍增。液體培養可得到大量小細胞團，經透明法與埋蠟切片觀察，有完整的表皮與封閉的微管束，具有體胚的結構。液體培養之細胞移至0.1 mg/l Kinetin、0.1 mg/l NAA與Sucorse 30 g/l的MS培養基，有最高的胚芽轉換率76.67 %。1 g的癒合組織細胞在培養一年後可以得到1.16×105個植株。再生的植株染色體倍數2n=24，與母本相同，定植後能正常開花。液體培養之細胞於氣舉攪拌與Super Spinner生物反應器培養，均因剪應力而造成細胞褐變死亡。
由種子直接誘導五個新鐵砲百合與1個台灣百合（L. formosanum wall.）的胚性癒合組織，6個百合品種中有4品種得到共9個具有良好再生能力的細胞系，可以在液體培養中不但得到分離的細胞團塊，且植株再生能力良好，亦可利用於液體培養大量增殖。

ABSTRACT
We investigated the somatic embryogenesis on friable callus of Lilium×formolongi cv.”Norikula” in suspension culture. The in vitro bulb was developed from sowed seeds on MS basal medium supplement with 30 g/l sucrose. The meristematic callus of L.×formolongi cv.”Norikula” were proliferated from in vitro bulb scales placed on MS basal medium supplement with 0.1 mg/l NAA, 90 g/l sucrose and 0.8 % Agar. Cell suspension cultures were established for embryogenesis in MS basal medium supplemented with 0.1 mg/l NAA and 90 g/l sucrose. We obtained a lot of somatic embryos from suspension culture of meristematic callus. The structure of somatic embryo was proved by tissue anatomy.
The optimal medium for suspension culture was MS basal medium supplemented with 0.1 mg/l NAA and 30 g/l sucrose, and the cell fresh weight could be double every 4 weeks. Maximum somatic embryos regeneration ratio was achieved 76.67 % in MS basal medium supplemented with 0.1 mg/l NAA, 0.1 mg/l kinetin and 30 g/l sucrose. A total of 1.16 ×105 plants can be produces from 1 g (fresh weight) callus through somatic embryogenesis. Plantlets derived from somatic embryo were diploid (2n=24) and flowering after transfer to soil for 9 months. Cell clumps cultured in Super Spinner bioreactor and air lift stir bioreactor for mass propagation were turned brown and dead by shear stress.
6 cell-lines from 3 species of L.×formolongi were collected and 3 cell-lines from L. formosanum were collected, too. All of those cell-lines were grown well and obtained meristematic nodular callus from suspension culture.
