[Study on seed quality test and quality standard of Platycodon grandiflorum].
OBJECTIVE
To study quality test, and establish quality classification standard of Platycodon grandiflorum.


METHODS
The seed quality and planting quality of P. grandiflorum from different producing areas and in different growing years were 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.
