Insect photoperiodism: the "T experiment" as evidence for an hourglass mechanism

    Abstract:

    "T experiments" demonstrate that the clock controlling termination of larval diapause in Ostrinia nubilalis is an hourglass mechanism that measures 8 hours of darkness. Circadian oscillations are not involved in photoperiodic time measurement in this species.

    Biological Clocks and Seasonal Responses

    The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
