The present invention provides a method for breeding micropropagation of Dendrobium, protocorm of Dendrobium candidum is produced by seed induced protocorm induced protocorm, protocorm proliferation induced by high efficiency, Regeneration Shoots, shoots after rooting of regenerated plants. The regenerated plants grew to 5 6 leaves, began the acclimatization, after a week of acclimatization, the seedlings can be transplanted out of normal growth. The invention of Dendrobium protocorm by micro reproduction of protocorm like bodies, the number doubled the rapid expansion of the number of seedlings in the future, to speed up the process of rapid propagation of Dendrobium seedlings, significantly increased the reproductive efficiency of Dendrobium seedlings, the highest propagation coefficient can reach 23, thus saving a lot of manpower and material resources. The present invention provides a highly efficient breeding method for Dendrobium candidum, but also can provide reference for other orchid plant breeding.

技术介绍
石斛是兰科(Orchidaceae)石斛属Dendrobium多年生草本植物,又名黄草,也称吊兰和金铰,是一种名贵稀有的中药材,素有“千金草”、“人间仙草”之称。医学经典《道藏》中称铁皮石斛为中华九大仙草之首,民间将其称为救命仙草(孙永玉等,药用石斛丰产栽培技术.2014)。铁皮石斛Dendrobium officinale又名黑节草,俗称铁皮枫斗,为我国特有的名贵药材。东汉末年的《神农本草经》中就有应用铁皮石斛记载,《本草纲目》、《中药大词典》等我国古代多部医学著作中都有铁皮石斛入药的记载。现代生物技术分析表明,石斛含有多糖、菲类、生物碱类、氨基酸类、酚类、芴酮类、倍半萜类、香豆素及挥发油等多种药用有效成分(张光浓等.中草药,2003,34:1005-1008),多糖和生物碱是石斛兰中最重要的生物活性化合物(Yang et al.Acta Physiologiae Plantarum,2015,37:94),具有滋阴清热、清音明目、益胃生津、止痛、提高免疫力等功效。野生石斛对生长条件要 ...
【技术保护点】
一种铁皮石斛微繁殖育种方法,其特征在于包括如下步骤:1)将铁皮石斛种子接种在萌发培养基上诱导产生原球茎;2)将原球茎接种于微繁殖培养基上培养,得到类原球茎;3)将类原球茎转移到分化培养基中诱导芽苗分化,待分化的芽苗长到1cm‑2cm左右时,转移到生根培养基诱导生根,最终长成完整植株;所述的萌发培养基为基本培养基+6‑BA 0.1‑2mg/L+NAA 0.05‑0.5mg/L。所述的微繁殖培养基为1/2MS培养基或MS培养基+6‑BA 0.5‑2.0mg/L+NAA 0.1‑0.5mg/L;所述的分化培养基为1/2MS培养基或MS培养基+6‑BA 2.0‑5.0mg/L+NA ...
