Seasonal Changes in the Circadian Rhythm of Gas Released from Harvested Cucumbers

Vegetables and fruits are known to have long-lasting biological reactions even after harvesting. Volatile components may be released as a response stimulation or injury. We measured the concentrations of volatiles from cut surfaces cucumbers their harvest analyzed relationship between time were gas concentrations. The results showed that indicate circadian rhythm. previously reported rhythm was 6 hours per cycle in summer, i.e., vernal equinox autumnal equinox, 24 winter, autumn equinox. emitted cucumber sections more detail this paper found rhythms differ among spring, seasons. one 8 mixed 12 autumn.
