对薏苡、红花、曼陀罗、尾穗苋和月见草等５种常见药用植物的种子，采用ＴＴＣ或ＢＴＢ生活力快速测定法、培养皿室内发芽率测定法、田间出苗率测定法，研究其发芽能力的差别。结果表明，除月见草外，其余４种药材种子在田间的实际出苗能力，可直接或间接地用室内发芽能力的测定来估计。
The seeds of five common medicinal plants such as Job’s tears, safflower, Datura, Amaranthus retroflexus, and evening primrose were determined by TTC or BTB viability assay, indoor germination rate test of petri dish, , To study the differences in their ability to germinate. The results showed that in addition to the evening primrose, the other four kinds of medicinal seedlings actual seedling in the field can be directly or indirectly assessed by indoor germination ability.
