摘 要 ：进行了四种培养基对朵朵香(Cymbidium goeringii（Rchb.f．）Rchb.f.〕种子萌发生长影响的试验。其结果是在MS培养基上，根茎较粗壮。进行了不同成熟度种子的萌发试验，结果表明授粉后九个多月的种子已达到生理成熟。研究了激素对根茎分化出芽的影响，NAA与BA配合使用时，NAA用量高于BA，则根茎继续生长不分化出芽；NAA低于BA时，根茎分化出芽。但将芽再转入无激素或NAA于BA的培养基时，并不能促进芽生根，而是芽停止生长，芽的基部又长出根茎。

Abstract:The effect of four culture media on the germination of seeds of Cymbidium goeringii was studied. MS medium is superior to SH/2, VW and Knudson media. The peicentages of germination of seeds in different maturity were calcu- lated. About three months before the dehiscence of the capsule, the seeds are ready for germination. The effects of hormones on the differentiation of the rhizomes were studied. When the amount of NAA added to the medium is greater than that of BA, the rhizomes remain to form rhizomes; when BA is greater than NAA, the rhizomes differentiate to form buds. But, if the buds are transfered into the medium without hormone or with 10% coconut milk, the buds stop to grow and new rhizomes grow out from the basal portions of the buds.
