[Effect of polysaccharides content of tissue culturing seedlings on Dendrobium candidium under sound wave stimulation].

OBJECTIVE To detect the polysaccharides content of tissue culturing seedlings on Dendrobium candidium under special sound wave stimulation. METHODS The content of polysaccharides was detected by phenol-vitriol colorimetry method. RESULTS The polysaccharides content of the groups stimulated continuously for 24d was higher obviously than the content of the control groups. CONCLUSION The stimulation of the special sound wave promoted markedly the synthesis of polysaccharides in D. candidium. It may affect obviously the metabolic pathway of polysaccharides in D. candidium.
