摘　　要：目的： 制定射干种子的质量分级标准。 方法： 通过测定不同产地的射干种子净度、千粒重、含水量、生活力、发芽率,观察种子的外部特征,使用SPSS 13.0软件,利用聚类分析方法,初步制订了射干种子的质量分级标准。 结果： 射干一级种子黑亮、圆润饱满,净度≥98％,千粒重≥28.00 g,含水量≤12.8％,生活力≥90％,发芽率≥85％;二级种子黑色、较饱满,净度≥92％,千粒重≥20.00 g,含水量≤12.8％,生活力70％~90％,发芽率65％~85％;三级种子深褐色、瘦瘪,净度≥86％,千粒重≥20.00 g,含水量≤12.8％,生活力≥50％,发芽率≥40％。 结论： 目前市场上射干种子的净度大多在90％以上,千粒重为15.27~30.76 g,但不同产地来源射干种子的生活力、发芽率差别较大。Objective ： To propose the seed quality standard of Belamcanda chinensis. Method ： The seed purity, 1 000-grain weight, water content, vitality, germination rate of seed of B. chinensis from different producing areas were measured, and seed characteristics were observed. Cluster analysis was used to analyze to data. Result ： The first level seed was lustrously dark and thoroughly rounded, seed purity was above 98%, 1 000-grain weight was above 28.00 g, water content was lower than 12.8%, vitality was over 90%, germination rate was over 85%. The second level seed was dark and relatively rounded, seed purity was above 92%, 1 000-grainweight was above 20.00 g, water content was below 12.8%, vitality was between 70%-90%, germination rate was between 65%-85%, the third level seed was puce, seed purity was above 86%, 1 000-grain weight was above 20.00 g, water content was below 12.80%, vitality was over 50%, germination rate was above 40%. Conclusion ： The seed purity of B. chinensis was almost above 90%, and 1 000-grain weight was between 15.27 and 30.76 g. The vitality and the germination rate of B. chinensis seeds from different sources varied obviously.
