In order to explore the effects of iodine on seed germination of rice, the seed of early indica rice Zhongzao 39 were soaked under 8 concentrations of iodine. The results showed that low concentration of iodine solution （0.0001%~0.001%） could greatly improve the activity of rice seeds, reduce the time of 50% germination and mean germination time，and improve the synchronicity and germination rate. It is very important to study the action mechanism of iodine on seed priming of rice.
