Abstract:
Objective: To study the quality testing method for the seeds of Silybum marianum, so as to provide the basis for the development of testing procedures and quality grading standard for the seeds of S. marianum. Methods: Refering to "The International Seed Testing Rules" and "China Crop Seed Testing Rules" to carry out the quality testing for the seeds of S. marianum. Results: The seed cleanliness was analyzed by winnowing method; The authenticity was identified by morphological appearance compared with 1000 grain weight by 1000 grain weight determination method; The germination conditions for seed germination were washed with running tap water before 2 h, the double filter paper was used as germination bed, and the seeds were incubated at 20 ℃, 8000 lx light, counting time for 4-14 d; The viability was determined by electrical conductivity method. Conclusion: The method is simple and reliable to the quality testing for the seeds of S. marianum.
