title: [Study on seed quality detection and quality standard of Belamcanda chinensis].
abstract: OBJECTIVE
  To propose the seed quality standard of Belamcanda chinensis.
  
  
  METHODS
  The seed purity, 1000-grain weight, water content, vitality, germination rate of seed of B. chinensis from different producing areas were measured, and seed characteristics were observed. Cluster analysis was used to analyze to data.
  
  
  RESULTS
  The first level seed was lustrously dark and thoroughly rounded, seed purity was above 98%, 1000-grain weight was above 28.00 g, water content was lower than 12.8%, vitality was over 90%, germination rate was over 85%. The second level seed was dark and relatively rounded, seed purity was above 92%, 1000-grainweight was above 20.00 g, water content was below 12.8%, vitality was between 70%-90%, germination rate was between 65%-85%, the third level seed was puce, seed purity was above 86%, 1000-grain weight was above 20.00 g, water content was below 12.80%, vitality was over 50%, germination rate was above 40%.
  
  
  CONCLUSIONS
  The seed purity of B. chinensis was almost above 90%, and 1000-grain weight was between 15.27 and 30.76 g. The vitality and the germination rate of B. chinensis seeds from different sources varied obviously.
