Effects of food concentration on the duration of reproductive period and the formation of mictic female in different strains of freshwater rotifer Brachionus calyciflorus
食物浓度和品系对萼花臂尾轮虫生殖期历时和混交雌体形成的影响

Strain is one of the most important internal factors which determine the micitc female formation and resting egg production in rotifers. Studies on the differences of mictic female formation among different rotifer strains not only can accumulate material for demonstrating the role of genetic factors in determining micitc female formation but also are important for selecting suitable rotifer strains for the mass production of resting eggs. In this study, the effect of food concentration(2.0, 5.0, 8.0 and 11...
