were abandoned three months after strobilation, these podocysts can still germinate. These podocyst were treated in three conditions, including feeding and aeration, and only aeration, only feeding. The rate of podocyst germination were 69.08%, 48.83% and 34.90%, respectively. According to the results, aeration significantly promoted the podocyst germination of , and the rate of podocyst germination with feeding was higher than that of no feeding group. As a strategy to for passing through adverse conditions, podocysts germination was more important to the asexual reproduction progress by podocyst. When dissolved oxygen content was not the limiting factor for the podocyst germination in this experiment, turbulence current by aeration eight be the main factor to promote prodocyst germination, which was the same as the turbulence current made by zooplankton to some extent. Although the prodocyst of can not eat any food, some secretions in vitro by food may be a motivator to induce the prodocyst germination of , which is same as the turbulence current by aeration. The mechanism of prodocyst germination of needs further researches
