| 摘 要： | 从野生球花石斛(Dendrobium thyrsiflorum)根系中分离到Dt1、Dt2、Dt5、Dt6、Dt7、Dt8 共6株真菌,将其接种到铁皮石斛(Dendrobium candidum)和球花石斛组培苗的根系上,定期测定石斛苗的株数、株高、叶数、新芽数等指标,并与不接种的石斛苗进行比较。试验结果表明,Dt5号和Dt8号真菌的接种效果最好,地上植株和地下根系生长均良好,株数增多、株高增加、落叶减少,新芽和新根萌发,因此它们对于石斛组培苗的成功栽培具有实际应用价值。

| Abstract: | From the roots of wild Dendrobium thyrsifoorum, six strains of orchid mycorrhizal fungi (Dt1, Dt2, Dt5, Dt6, Dt7, and Dt8) were obtained and inoculated onto the roots of tissue-cultured Dendrobium thyrsiflorum and Dendrobium candidum seedlings The growth of the seedlings inoculated with fungi was compared with that of those not inoculated. The results showed that inoculation improved growth of tissue-cultured Dendrobium seedlings and increased the number of buds and roots. And the effects of fungi Dt5 and Dt8 were better than that of the other fungi. It is of a potential value, that these two fungi are applied to Dendrobium cultivation. |
