The effects of radiation dosages of ~ 60Co-γ-ray on physiological index of the Aloe were studied. The results showed that: the content of starch irradiated by γ-ray of 10 Gy was highest and byγ-ray of 20Gy,lowest among all treatments. The content of protein in the irradiation with γ-ray was highest; the content of sucrose and rate radioactivity of SOD, POD and CAT in the irradiation with γ-ray of 20Gy were highest. There was a good positive correlationships between rate radioactivity of PPO and the dosages of ~ 60Co-γ-ray.
