Effect of Concentrated H<sub>2</sub>SO<sub>4</sub> Treatment on Seed Germination of <i>Glycyrrhiza </i><i>u</i><i>ralensis</i> Fisch

以甘草种子为材料，通过研究浓硫酸用量、处理温度和处理时间对甘草种子萌发的影响，探究促进甘草种子萌发的最佳试验处理。结果表明：随着浓硫酸含量的增加，在添加5 ml浓硫酸后，100 g种子的发芽率为94.7%。在此基础上，研究了处理时间和温度对种子发芽的影响。发现在20℃~25℃的温度下，100 g甘草种子处理120~150 min后，其发芽率可达95%以上。因此，生产中可采用该方法处理甘草种子来促进萌发，为甘草人工种植提供科学依据。Using Glycyrrhiza uralensis seeds as materials, the effects of concentrated H2SO4 content, treatment temperature, and treatment time on the germination of Glycyrrhiza uralensis seeds were studied to explore the best experimental treatment to promote the germination of Glycyrrhiza uralensis seeds. The results showed that with the increase of the content of concentrated H2SO4, the germination rate of 100 g of seeds was 94.7% after adding 5 ml of concentrated H2SO4. On this basis, the effects of treatment time and temperature on seed germination were studied. It was concluded that the germination rate of Glycyrrhiza uralensis seeds could reach more than 95% when treated at 20˚C~25˚C for 150~180 min. Therefore, this method can be used to promote the seed germination of Glycyrrhiza uralensis and provide a scientific basis for artificial cultivation of Glycyrrhiza uralensis.
