Objective:
To establish the quality classification criteria of Oldenlandia diffusa seeds.
Method:
Thirty batches of O. diffusa seeds from different provenances with different collecting time were selected. And the seed germination percentage, seed purity, weight per 1 000 grains, moisture content and seed viability were determined and analyzed through SPSS 11.0 software.
Result And Conclusion:
Seed germination percentage was selected as the main index for classification, while seed purity, weight per 1 000 grains and moisture content could be used as references. The quality classification criteria of O. diffusa seeds have been initially established.
