铁皮石斛培养的产业化研究

目的　筛选适宜的铁皮石斛不定芽增殖与生根培养基 ,选择适合继代扩繁的不定芽高度。方法　在相同培养条件下 ,不同高度的不定芽在不同的增殖与生根培养基中生长 ,对结果所产生的不同生长状况 ,进行显著性差异检验及综合分析。结果　不同高度的不定芽之间有显著差异 ,不同的增殖与生根培养基之间有显著差异。结论　铁皮石斛继代以 (1.2± 0 .1) cm高的不定芽为宜 ,增殖培养基以 MS添加 BA1.0 m g/ L、NAA0 .2 mg/ L 为佳 ,生根培养基以 1/ 2 MS添加 NAA 0 .2 mg/ L为佳。

Studies on industrialization cultivation of Dendrobium candidum

Object To optimize the fitting culture media for multiplication of adventitious bud and ra-dication of Dend robium candidum Wall. ex Lindl. and the length of adventitious bud for succesive transfer multiplication. Methods In the same culture condition, the adventitious bud with different length developed in the various culture media for multiplication and radication. Facing the different growth status, the diversity test and general analysis were carried on for them. Results There were significant difference in different length of adventitious bud, difference between the multiplication and radication of culture media. Conclusion The adventitious buds in (112𫍳) cm length are superio r fo r succesive transfer multiplication, M Sadding BA 110 mg/L, NAA 0.2 mg/L is the best media for the adventitious buds multiplication, 1/2 M S adding NAA 0.2 mg/L is the test media for radication.
