title: [Study on seed quality test and quality standard of Changium smyrnioides].
abstract: OBJECTIVE
  To study seed quality test methods, and provide basis for establishing seed quality standard of Changium smyrnioides.
  
  
  METHODS
  According to the seed testing regulations, the seed quality of C. smyrnioides from different producing area and in different growing years was measured.
  
  
  CONCLUSIONS
  The range of seed purity, weight per 1000 seeds, seed moisture content, seed viability were determined and the primary seed quality classification standard was established.
