The circadian rhythm of mating-reactivity in Paramecium bursaria was investigated to clarify its adaptability to reversed light-dark cycle as well as to light-dark cycles at various period. Paramecia cultured with lettuce extract inoculated with food bacteria were killed with ammonium sulfate in mating reactive state by an auto-killing apparatus every 2 hours and tested its mating reactivity by mixing with living tester cells. The following results were obtained: the phase of rhythm was reversed in 2 to 3 day time and the period was changed between 12 and 36 hrs. These results are discussed and compared with those of other animals previously reported. |
