title: [Study on seed quality test and quality standard of Prunella vulgaris].
abstract: OBJECTIVE
  To study seed quality test, and establish seed quality classification standard of Prunella vulgaris.
  
  
  METHODS
  The seed quality and planting quality of P. vulgaris from different population were measured and these indexes were analyzed by K-clustering.
  
  
  CONCLUSIONS
  The seed purity, 1000 seeds weight, seed moisture content, seed viability of the seed of P. vulgaris from different population were measured, and the seed quality classification standard of P. vulgaris.
