摘　　要：应用ＹＡＧ倍频激光器对中华大蟾蜍受精卵、四细胞期胚胎、囊胚期胚胎分别进行照射。实验结果表明：用激光微束照射胚胎能产生各种畸形胚；激光对蟾蜍不同时期胚胎的影响不同；激光对胚胎发育能产生抑制作用；胚胎死亡率与所用激光微束能量密度密切相关。Applying YAG double-frequency laser microbeam resp ectively irradiated fertilized eggs,4-cell-stage,blastula stage embryos of Bufo bufo gargarizans.The experimental results show that:using laser micr obeam irradiated embryo,abnormal embryos are formed,and the effects on laser irr adiated different stage embryos of Bufo bufo gargarizans are differe nt.The inhibition in emb ryonic development may be produced by laser irradiation.The mortality of the emb ryos is closely ralated to energy densities of the laser beam.
