摘　　要：简述了植物组织培养方法与离子束辐射相结合这一新诱变技术的研究进展,从原理、操作步骤、分子机理等诸方面对该方法进行了阐释。该诱变技术具备传统辐射诱变技术所不具备的优势,从而能够为利用无性繁殖技术进行后代繁衍的植物提供新的育种思路。与此同时,使用该方法还能够开展植物组织细胞的传能线密度(Linear energy transfer,LET)生物学效应的研究,从理论上及实践上进一步优化该技术。About a new mutation breeding method which combines plant tissue culture technique with heavy ion beam irradiations were discussed in this paper with the principles, operation steps, molecular mechanisms, etc. The mutation methoddeveloped a few advantages coming from plant tissue culture, which can produce offspring by asexual ways. Meanwhile, using this method, the study of biological effects of high energy particles with different linear energy transfer values on plant tissues or cells can be explored and optimized in theory or practice.
