摘　　要：以桑寄生种子为试材,采用相关指标测定和外观形态观测的方法,研究了桑寄生种子的百粒质量、含水量、发芽率、发芽势等指标,通过进一步的数据分析制定桑寄生种子的质量分级标准。结果表明:可将桑寄生种子的质量分为3级,一级品种纯度和净度为100%,发芽率不低于75.0%,水分不低于50.0%,百粒质量不低于60.0g;二级品种纯度和净度为100%,发芽率不低于70.0%,水分不低于40%,百粒质量不低于50.0g;三级品种纯度和净度为100%,发芽率不低于60.0%,水分小于40.0%,百粒质量小于50.0g。该方法制定出的桑寄生种子质量分级标准适用于桑寄生种子生产的质量控制。Taxillus chinensis （DC.）Danser seed was used as material, through the detection on 100-seeo weight, water content, germination rate, germinative energy of Taxillus chinensis, and observation on seed external characters, the primary seed quality classification standard of Taxillus chinensis was preliminarily formulated. The results showed that the seed quality grading of Taxillus chinensis was described as three grades. For the first grade seed, purity and clarity all were 100%, seed germination rate 〉75.0%,water content 〉50%, 100-seed weight ≥60. 0 g; for the second grade seed, purity and clarity all were 100%, seed germination rate ≥70.0% ,water content ≥40%, 100-seed weight 〉50.0 g; for third grade seed, purity and clarity all were 100 %, seed germination rate 〉60.0%, water content 〈40%,100-seed weight〈50.0 g. This quality classification standard of Taxillus chinensis could be used at the quality control standard of Taxillus chinensis.
