我国药用植物资源丰富,种类繁多。为了更好地利用发掘,有必要对一些重要药用植物进行引种驯化,变野生为家种。在引种驯化的第一步,必然涉及到种子的生物学特性,尤其是很多长在高寒山区或喜荫、速生的药用植物,其种子常因多种原因引起休眠,休眠期长达0.5～2年,即播种后要等第二年甚至第三年才能萌发,有的发芽极不整齐,对生产有一定的影响。为了掌握这一类药用植物种子休眠及萌发习性,解决发芽困难问题,以加快引种驯化的步伐,我们进行了本课题的研究,对三十多种药用植物种子的休 Medicinal plants in our country are rich in resources and varied in variety. In order to make better use of excavation, it is necessary to introduce and domestication of some important medicinal plants and to change wild animals into families. In the first step of introduction and domestication, it is bound to involve the biological characteristics of the seeds, especially in the alpine mountains or shade, fast-growing medicinal plants, the seeds often due to a variety of causes caused by dormancy, dormancy up to 0.5 ~ 2 years, that is, after sowing the second or even the third year germination, some very irregular germination, the production has a certain impact. In order to grasp the dormancy and germination habits of the seeds of this kind of medicinal plants, to solve the problem of germination difficulties and to speed up the pace of introduction and domestication, we carried out the research on this subject and studied the rest of the seeds of more than thirty kinds of medicinal plants
