摘要: 本研究以西藏虎头兰种子为外植体,探讨培养基对种子胚萌发的诱导、外源激素对继代增殖、生根培养的影响,并进行移栽试验。结果表明:1/2MS对原球茎的诱导有较好的促进作用;l/2MS +TDZ 0.5 mg/L+NAA 0.1 mg/L。对芽的诱导和增殖起明显的促进作用;1/2MS +IBA 0.2 mg/L对西藏虎头兰的壮苗生根起关键性作用因素;碎树皮为栽培基质的移栽成活率达96%。试验对西藏虎头兰种苗快繁奠定了基础。

Abstract: Using the seeds of Cymbidium tracyanum L. as the explant, the effects of different medium component on induction of protocorm, and plant growth regulators on the tissue culture and rapid propagation were studied in this paper. The result showed that:1/2MS affected the induction rate of protocorm;The best Culture medium for obviously enhanced the induction and proliferation of buds was l/2MS +TDZ0.5 mg/L+NAA0.1 mg/L;The Culture medium of 1/2MS +IBA0.2 mg/L played the key role in the process of rooting and seedling growth;Culture medium selection was a critical factor greatly influencing,the survival rate reached 96% of the transplants.The study laid the foundation for rapid propagation of Cymbidium tracyanum L..

Key words: Cymbidium tracyanum L, seed;asymbiotic germination, in vitro seedling
