Abstract:
OBJECTIVETo establish the quality classification criteria of Oldenlandia diffusa seeds.
METHODThirty 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 CONCLUSIONSeed 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.
