Abstract: The seed of wheat (Triticum asstivum) and rice (Oryza sative) had been irradiated with different doses (0,10KR, 20KR, 30KR) of 60Co ?-ray before sowing. The experiment indicated that the growth of radicles and leafs were inhibited by irradiation, but, no effect of 60Co ?-ray on coleo-ptile growth were showed at seedling stage. The germination of seed both in wheat and rice were not affected by irradiation. The experiment also showed that the inhibition effect on growth is much more in early stage of seedling than that in old stage.The results of analysis by peroxidase isozymes were illustrated in Fig4and Fig5 (a, b). There were differences in the zymograme patterns of the peroxidase isozymes of radicle between the irradiated and non-irradited seeds of wheat and rice. There were two cathode bands in zymograme of radicle with ?-ray more than of non-irradiated.However, there was no obvious difference on Peroxidase leaf. According to above, it seems there are no relative between the changes of morphogenesis structure and peroxidase isozymes.

Key words: Peroxidase isozymes, Cathode, Wheat, Rice
