目的 研究水飞蓟种子的质量检验方法,为制定水飞蓟种子检验规程和质量分级标准提供依据.方法 参考《国际植物种子检验规程》和《中国农作物种子检验规程》的方法对水飞蓟种子的质量进行测定.结果 种子的净度分析采用风水选法;真实性鉴定采用外观形态比较;用千粒法测定千粒质量;发芽条件为在种子发芽前用自来水冲洗2 h,以双层滤纸为发芽床,在20 ℃条件下、8 000 lx光照培养,计数时间为4～14 d;用电导率法测定生活力.结论 建立研究的水飞蓟种子的质量检验方法简便可靠.

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 1 000 grain weight by 1 000 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 ℃, 8 000 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.
