野生地榆种子萌发特性研究

以野生地榆（Sanguisorba officinalis）种子为试材，对其萌发特性进行了研究。结果表明：地榆种子长约2.548mm，椭球形，灰褐色至紫黑色，千粒重为2.471g；种子休眠属种壳休眠，破除休眠可采用98%浓硫酸处理，以酸蚀30min为宜，发芽率为85.33%；最适萌发温度为20℃；200mg/L赤霉素浸种发芽率达到86.67%。

The Study on the Germination of Seeds of wild Sanguisorba officinalis Linn

Using the seeds of wild Sanguisorba officinalis as experiment materials, the germination characteristic was studied in this paper. The result shows that: The seeds are about 2.548mm long, oblate, and are yellow-gray or brown-black. The weight is 2.471g per thousand-granule. The dormant character of the seeds is forcing dormancy caused by hard seed vessels. The dormancy could be broken down by 98% concentrated sulfuric acid. The most appropriate time is 30min. The highest germination rate is 85.33%. The optimum germination temperature is 20℃. When the seeds were soaked in 200mg/L GA the germination rate could reach to 86.67%.
