摘　　要：利用激光微束,并选用适当的功率密度可将小冰麦异附加系花粉细胞染色体切割成2～3个片段,这个技术的建立为激光微束应用于染色体片段DNA微克隆及基因定位提供可能。By using the laser microbeam with a certain power density the chromosomes of pollen mother cells of allo-addition line of wheat with Agropyron intermedium can be cut into 2-3 segments. The establishment of this technique provides the possibility to make use of the laser microbeam in cloning of DNA and locating of genes.
