Abstract
Objective: To establish the seed quality classification standard of Vaccariae Semen. Method: 34 batches of Vaccariae Semen seeds samples from different producing areas of the whole country were selected. the seed purity, 1 000-grain weight, water content and the germination rate of the seeds samples were measured. K-means analysis was applied for the date analysis. The primary seed quality classification standard of Vaccariae Semen was formulated. Result: Seed purity and seed germination rate were selected as the primary indicators, and the other indicators provide the important reference, the Vaccariae Semen seeds were classified into 3 grades. Conclusion: The quality classification standard of Vaccariae Semen seeds were initially established and it can be used as the reference standard.
