title: [Effects of cumulative parthenogenetic generation and age of amictic female on the reproduction of rotifer Brachionus calyciflorus].
abstract: Effects of cumulative parthenogenetic generation and age of amictic female on mictic female production and fecundity of the rotifer Brachionus calyciflorus were studied by means of individual culture. The results showed that percentage of total mictic females produced by the parental females in each of four generations increased with the increasing generations. More mictic females were produced from younger maternal amictic females. Amictic offspring from older mothers produced more mictic daughters. There was no significant effect of the cumulative parthenogenetic generation on the mean number of eggs produced by amictic females per life cycle, and no significant effect of the age of amictic female on the mean number of eggs produced by the offspring of amictic female.
