太空春石斛组培快繁黄苗现象成因初探

A preliminary probe into rapid propagation of Yellow Seedlings in Outer Space Dendrobium Nobile Tissue Culture

以太空春石斛丛生芽为试验材料,初步研究了基本培养基、激素和附加物质香蕉对黄苗现象的影响。试验结果表明:基本培养基以1/2MS培养基最适宜;激素NAA和IBA对黄苗影响差异不显著,NAA0.2mg/L较适宜;而附加物质香蕉对黄苗的影响较大,黄苗较严重。

An investigation was made into the effects of basic culture media, plant growth regulators and banana juice on yellow seedlings in outer space Dendrobium Nobile tissue culture, finding that the best media 1/2MS and NAA 0.2 mg/L were best for seedlings and banana juice could promote more seedlings to turn yellow.
