    Abstract:
    OBJECTIVE: The aim of this study was to optimize the testing methods for seed quality, and to provide a basis for establishing seed testing criterion and quality standard of Amomum villosum. METHOD: Referring to the International Seed Testing Rules made by ISTA and Rules for agricultural seed testing, the seed quality of A. villosum from different collection areas was measured. RESULT: The samples weight of A. villosum for purity analysis were at least 500 g and for test were at least 50 g. Verification of genuineness was assayed by seed appearance comparing and weight of per hundred seeds was determined, the moisture content test was carried out by high temperature drying method (3 hours). The seeds were stored in wet sand for 20 days and then dipping in the 100 mg x L(-1) GA3 for 30 days before germination, seeds on filter papers germinated at 30/20 degrees C. The first germination-counting time was the 15th day of the test and the final time was the 50th day. Seed viability was tested by TTC method. CONCLUSION: The seed testing methods for quality items of A. villosum, including sampling, purity analysis, verification of genuineness, weight, moisture content, percentage germination and seed viability of A. villosum had been initially established.
