| Abstract: | This research adopts the plant tissue culture technology to do a series of study of the Dendrobium pierardii, such as： the induced differentiation, shoots proliferation, seedling cultivation, rooting and transplanting The results showed that： the appropriate medium for the induced differentiation of Dendrobium pierardii is MS ＋ BA 2.0 mg / L ＋ NAA 0.2 mg / L with the differentiation rate of 69.8 percent; the proliferation medium is MS ＋ BA 3.0 mg / L ＋ NAA 0.2 mg/ L with the proliferation of cultured 60d coefficient of 4.9; the seedling medium is 1/2MS ＋ NAA 0.2 mg / L ＋ BA 0.5 mg / L ＋ banana mud 10%; the rooting medium is 1/2MS ＋ NAA 0.5 mg/ L; and when the seedlings grew up to 3- 4cm high with 5-7 footings and the root length grew up tol-2 cm, the Dendrobium pierardii was transplanted to the water, then the survival rate of them reached above 75%. |
