title: [Effect of low temperature on cell synchronization division in suspension culture cells of Pinellia ternata].
abstract: OBJECTIVE
  To study the effect of low temperature on cell synchronization division in suspension culture cells of Pinellia ternata, in order to find a proper condition for cell synchronization.
  
  
  METHODS
  The loosened calli of P. ternata were used as materials. The effect of low temperature on cell synchronization division was studied and researched in suspension culture cells by the method of orthogonal experiment, the obtained experimental data was compared and analyzed through the analysis of range and analysis of variance.
  
  
  RESULTS
  After the low temperature treatment, the cell division index was increased in various degrees, among the total results, when the temperature was set at 8 degrees C for 24 hours and then recovered for 36 hours, the effect was the best, the mitotic index was significantly increased to 11.3%.
  
  
  CONCLUSIONS
  The low temperature could obviously influence the cell synchronization division in suspension culture cells of P. ternata, and the mitotic index was efficiently increased.
