摘要：Laboratory populations of three strains of Brachionus calyciflorus Pallas (Qingdao, Wuhu, and Guangzhou strains) collected respectively from River Huanghe, River Changjiang and River Zhujiang basins of China were cultured at 20°C 25°C, and 30°C with 3.0x10 6 cells/ml of Scenedesmus obliquus to investigate their resting egg productions. There were significant effects of both temperature and strain, independently and in interaction on resting egg production. The resting egg productions of the rotifers at 20°C and 25°C were not significantly different, but were lower than those at 30°C. Resting egg productions of the Qingdao and Wuhu strains were not significantly different, but were higher than that of the Guangzhou strain. The total production of fertilized mictic females depended on the production of total females and the mixis and fertilization rates. Among all the strain-temperature combinations, the resting egg productions of the Wuhu and Qingdao strains at 30°C were the highest (1202.33±102.50 and 1258.67±403.45 ind./10ml/12d, respectively).
