    • The response of plants to periods of day/night is termed photoperiodism.
    • Some plants require the exposure to light for a period exceding a well-defined critical duration known as long day plants, whereas others must be exposed to light for a period less than this critical duration before the flowering is initiated in them, known as short day plants.
    • The plants in which there is no correlation between exposure to light duration and induction of flowering response; such plants are called day-neutral plants.
    • The site of perception of light/dark duration are the leaves.
    • There is a hormonal substance, which migrates from leaves to shoot apices for inducing flowering only when the plants are exposed to the necessary inductive photoperiod.
