化学诱变提高植物抗逆性的研究进展
Chemical Mutagenesis in Improving Plant Stress Resistance
摘要
Abstract
Chemical mutagenesis is a traditional breeding technique in improving plant resistance to cold,drought,salt,alkali and etc.,which is favored by breeders.Plant tissue culture technology is an effective way to achieve rapid reproduction of cell or plantlet.Combing these two technologies,the mutation frequency can be improved greatly and the range of plant genetic variation would be expanded.In recent years,the combination of chemical mutagenesis and biotechnology has shown a positive prospect in the resistance breeding,and has important practical significance for breeding new crop varieties.This paper mainly reviews the characteristics of chemical mutagenesis,the mutagenesis mechanism and application methods of chemical agents[mainly ethyl methane sulfonate(EMS)and sodium azide(NaN3)],mutagenesis efficiency and its influencing factors.And the applications of chemical mutagenesis in plant stress resistance breeding are also introduced.关键词
