自20世纪80年代中期发现离子束生物效应以来,离子注入技术已被应用于生物改良、生命起源和进化以及环境辐射生物学效应等多个研究领域。其中,在植物遗传育种、创造新种质资源方面的成果尤为突出。药用植物是中药重要的原材料之一,其遗传育种工作对提高中药材的产量和质量起着十分关键的作用。重点综述了离子束生物技术及取得成果,然后指出药用植物的研究现状,并对离子束生物技术在药用植物育种中的应用进行了展望。

Ion beam implantation technique has been applied to many research fields, such as organism improvement, life origin and evolution, and radiobiological effect of the environment, since the mutagenic effects of ion beam had been discovered at the mid of 1980′s. Especially ion beam biotechnology has obtained outstanding result in introducing plant breeding and creating new germplasm resources. Medicinal plant is one of basic materials of traditional Chinese medicinal materials, which has direct relationship with the quality and curative effects of medicines. Therefore, their genetic breeding plays a very important role in the improvement of the yield and quality of traditional Chinese medicinal materials. In this paper, ion beam biotechnology, its obtained results, and present status of research on medicinal plants are expounded. Moreover, the prospects of its application to the medicinal plant breeding are pointed out.
