摘　　要：为了研究红大戟种子检验规程,为红大戟种子质量标准的制定提供依据,参照农作物种子检验规程的方法,通过对红大戟种子扦样、净度分析、种子真实性、千粒重、含水量、发芽率、生活力等常规指标进行对比分析,找出适合红大戟种子的检验方法。结果表明,红大戟种子净度分析试样不少于0.3 g;采用外观形态观察鉴定法鉴定种子真实性,千粒法测定种子重量;131℃下烘6 h测定种子含水量,采用浓度为0.1%的TTC溶液25℃或TTC浓度0.5%,温度20~25℃条件下染色16 h测定种子生活力;种子消毒后25℃下(12 h光照/12 h黑暗)培养测定种子发芽率,发芽床为沙上。To study the seed inspection procedures of Knoxia roxburghii,and provide the basis for the formulation of seed quality standards of K.roxburghii.With reference to the method of crop seed inspection procedures,the conventional indicators such as seed sampling,purity analysis,seed authenticity,1000-grain weight,water content,germination rate,and viability were compared and analyzed to find a suitable test method for K.roxburghii seeds.The results showed that the purity analysis sample of K.roxburghii seeds was not less than 0.3 g,the seed authenticity was identified by morphological observation and identification method,and the seed weight was determined by thousand seed weight method.The seed moisture content was determined by baking at 131℃for 6 h,and the seed viability was determined by staining with TTC solution at a concentration of 0.1%at 25℃or TTC concentration of 0.5%at 20-25℃for 16 h.The seed germination rate was measured at 25°C(12h light/12h dark)after seed disinfection,and the germination bed was sand.
