A Tissue Culture Protocol for Propagation of a Rare Plant, Lilium speciosum Thunb. var. gloriosoides Baker

組織培養法繁殖臺灣稀有植物-艷紅鹿子百合

摘要


艷紅鹿子百合幼花苞培植體在含3mg/12,4-D及0.25mg/1BA的MS基本培養基中三個月可以產生可繼代培養、具分化全能性的癒傷組織。將癒傷組織移植到含0.1mg/1NAA,1g/1活性碳及170mg/1Nah2PO4可以形成小鱗莖,繼而發育成為小苗。艷紅鹿子百合可藉由鱗片-小鱗莖方法在試管內以8倍/三個月的速率大量增殖,經九個月的培養,己產生六千株試管內小苗。艷紅鹿子百合組織培養幼苗移植到溫室培養具98%存活率,栽培至第二年可抽莖及開花。

並列摘要


Floret explant of a local accession of Lilium speciosum Thunb. var. gloriosoides Baker produced subculturable totipotent calli on a Murashige and Skoog basal medium with a supplement of 3 mg/I 2,4-dichlorophe- noxyacetic acid and 0.25mg/l benzyladenine. The calli were able to form bulblets, which subsequently developed into plantlets on the MS basal medium supplemented with 0.1mg/l naphthalene acetic acid, 1 g/l active charcoal and 170 mg/l NaH2PO4. The rare lily was proliferated in vitro by a scale-bulblet cycling propagation method with a multiplication rate of eight times at three-month intervals. Finally, 6000 plantlets have been produced within nine months. We established 200 plants in the greenhouse under misty conditions for a four-week period with a 98% survival rate. These plants grew well and elongated with normal flowers in the second year.
