摘  要:
植物诱变技术是指利用外界因素加快物种遗传变异,在短期内获得有利用价值的突变体,为培育新种质、新品种及基因功能的研究等创造条件。相对于自然的选择,诱变技术具有高频率、广突变、周期短等特性。主要论述了常用的化学诱变、物理诱变、空间诱变和生物诱变等诱变手段,并详细介绍了上述诱变技术的诱变机理、生物学效应、常用的诱变方式及其在植物应用中的研究现状。针对现行各种诱变技术的不足提出了今后努力的方向。

摘  要:
Plant mutagenesis technology is using external factors to accelerate species variation and acquire some valuable mutants in the short period. This technology has been an important tool for new materials breeding, variety cultivation and gene function research. Compared with the natural selection, plant mutagenesis technology has more advantages, such as a higher mutant frequency, larger mutation range and shorter mutation period. This paper mainly introduces the mutational mechanism and biological effects of chemical, physics, space, biology mutagenesis, and their research progress of applications in plant in detail. Also some disadvantages of these technologies are mentioned and good suggestions for future development are proposed.
