射干种子解除休眠方法的比较研究

Comparative Study on the Methods of Releasing Dormancy of Belamcanda chinensis Seeds

摘要: 射干作为一种常用中药材，其种子具有休眠特性。经去种皮种子和完整种子对照，通过高温、吲哚乙酸、赤霉素处理的方法研究对射干种子发芽率的影响。结果表明，射干种子的种皮对种子的萌发具有阻碍作用。不同处理方式对种子的影响情况不同，在高温处理下，去种皮种子与完整种子的发芽率具有明显差异。

Abstract: The seeds of Belamcanda chinensis (L.) DC. as a common Chinese medicinal herb have dormancy characteristics. The effects on seed germination rate were studied by three treatments of high temperature, indole acetic acid (IAA) and gibberellin with the dried seeds of the dehulled seeds and the intact seeds as a CK. The results showed that the seed coat of shoot-dried seeds hindered the germination of seeds, and different treatments have different effects on seed germination rate. Under high temperature treatment, the germination rate of dehulled seeds and intact seeds is obviously different.
