摘要: 将玫瑰石斛组培苗叶片接种于含有不同激素的MS培养基上培养,以诱导原球茎的产生,然后将诱导出的原球茎进行增殖培养。结果显示,在MS+2.0 mg/L 2,4-D+2.0 mg/L BA+0.5 mg/L NAA的培养基上原球茎诱导效果较好,诱导率可以达到94%;原球茎在MS+1.0 mg/L BA+0.2 mg/L NAA的培养基上增殖速度较快且质地较硬、结构松散。本试验结果可为玫瑰石斛人工种子的研究提供一定的参考价值。

Abstract: The leaves of Dendrobium crepidatum tissue culture seedlings were inoculated on MS medium containing different hormones to induce the production of protocorm, and then the protocorm was cultured for proliferation.The results showed that the protocorm induction effect was better on the medium with MS+2.0 mg/L 2,4-D+2.0 mg/L BA+0.5 mg/L NAA, and the induction rate could reach 94%; the protocorm could be induced with fast proliferation, hard texture and loose structure on MS+1.0 mg/L BA+0.2 mg/ L NAA. The results of this experiment can provide some reference for the study of artificial seeds of Dendrobium crepidatum.

Key words: Dendrobium crepidatum, leaf, protocorm, artificial seed
