Rice embryos(Oryza,sativa L.cv.Zhen Shan 97)were irradiated with N_2laser at λ=0.3371μm and Nd:glass laser at λ=1.06μm in different dosages(e.g.30 min.60 min and 9 pulse,15 pulse)respectively.The change of DNA synthesis rate of embryos inthe early germinating period at 25°C were analysed with(~3H-TdR)incorporation method.The results indicated that the unschedule DNA synghesis were found in the embryos whichwere irradiated either by 30 min and 60 min of N~2 laser or 9 pulse and 15 pulse of Nd:glass laser

The results indicated that the unschedule DNA synghesis were found in the embryos whichwere irradiated either by 30 min and 60 min of N ~ 2 laser or 9 pulse and 15 pulse of Nd: glass laser
