title: [Comparative research on vitality and characteristics of seeds of Achyranthes bidentata in different producing area].
abstract: OBJECTIVE
  To study the germination property of the seeds of Achyranthes bidentata from different producing area, providing foundation for choosing the better seed resources.
  
  
  METHODS
  The germination rate, germination energy, germination index, vigor and the characteristics of the seeds of A. bidentata from different producing area were compared, and the relative electric conductivity was measured. The characteristics of the seed were recorded through the Anymicro DSS YT-5M microscope digital camera, and the differences were analyzed.
  
  
  RESULTS
  Seed from Henan Boai and Hebei Anguo showed the better germination rate, germination energy, germination index and vigor.
  
  
  CONCLUSIONS
  The seeds from both Henan Boai and Hebei Anguo showed the better quality.
