| 摘 要： | 以浙江雁荡山×云南广南种质的杂交组合茎段为外植体,筛选出1/2MS +IBA1.0 mg·L-1+6-BA1.0mg·L-1腋芽诱导培养基与1/2MS+IBA1.5 mg·L-1+6-BA0.5 mg·L-1芽增殖培养基,在浙江、云南、广西、湖南等159个铁皮石斛野生与人工种质中应用,腋芽诱导率达94.3％,具有较好的通用性；芽增殖培养时,不同种质分化出单芽、丛芽、原球茎3种增殖途径,增殖效果存在显著差异.研究结果表明,不同种质铁皮石斛的增殖对培养基有专用性需求,开发铁皮石斛无性系繁育专用培养基具有紧迫性和重要的应用价值. |

| Abstract: | The explants were obtained from stem segments of hybrid combination of Dendrobium officinale germplasms (Zhejiang Yandang Mountain×Yunnan Guangnan). The screened culture mediums for buds induction and multiplication, which were 1/2MS+IBA 1.0 mg·L-1+6-BA 1.0 mg·L-1 and 1/2MS+IBA 1.5 mg·L-1+6-BA 0.5 mg·L-1 respectively, were applied to 159 germplasms of D. officinale from Zhejiang, Yunnan, Guangxi, Hunan, etc. The medium for axillary buds induction had universality with 94.3% induction rate. During buds multiplication, there were significant differences in proliferation effect among germplasms, and three proliferation forms i.e. single bud, multiple buds and protocorm were differentiated from different germplasms. The results showed that different germplasms of D. officinale had specific requirements for culture medium. Therefore, developing special culture medium for breeding clones of D. officinale is urgent and has important application values. |
