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高于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。 The effect of four media on the germination and growth of Cymbidium goeringii (Rchb.f.) Rchb.f. Seeds was studied. The result is MS medium, rhizome stout. Germination tests of seeds of different maturity were carried out. The results showed that the seeds of more than nine months after pollination had reached physiological maturity. The effects of hormones on the budding of rhizomes were studied. When NAA was used in combination with BA, the rhizomes continued to grow and differentiated without NAA when the NAA content was higher than that of BA. When NAA was lower than BA, rhizomes differentiated and budded. However, when the shoots were transferred to medium without hormones or NAA higher than BA, buds did not promote rooting, but the buds stopped growing and the roots of the buds grew again.
