| photoperiod | <ecology> Recurring cycle of light and dark periods. The natural photoperiod is approximately 24 hours, and the ratio of light to dark hours slowly changes over the course of a year. In controlled experiments, the photoperiod is usually (but not necessarily) retained at 24 hours, and the light:dark ratio is typically constant. (09 Oct 1997) |

| photoperiodism | <biology> Events triggered by duration of illumination or pattern of light/dark cycles: often the wavelength of the illuminating light is important as for example in control of circadian rhythm in plants. See: phytochromes. (18 Nov 1997) |

Response of an organism to the relative duration of dark and light periods. In plants, photoperiodism may affect flower or seed development, vegetative growth, formation of bulbs and tubers, leaf shape, character and extent of branching, abscission (dropping of vegetative growth, ie, protective seed sheath) and leaf fall, root development, dormancy, and death.
