title: [Metabolism in Arctium lappa L. at the primary stage of germination].
abstract: OBJECTIVE
  To investigate the metabolic changes of the seeds at the primary stage of germination in Arctium lappa.
  
  
  METHODS
  By means of electrophoresis the changes of peroxidases and soluble proteins were assayed at the primary stage of germination.
  
  
  RESULTS
  The color of some original bands was enhanced, some original bands disappeared, and some new bands were detected in peroxidase patterns during the germinating process. The color changes were the main expression in soluble protein patterns. The bands of soluble proteins changed most obviously at 96 h and 120 h after germination.
  
  
  CONCLUSIONS
  It follows that the metabolic process in the seeds of Arctium lappa at the stage of germination is complex and 96 h and 120 h after germination are the key times of metabolism.
