Detailed explanation-1: -The response of a plant to change in relative length of day and night is called photoperiodism.
Detailed explanation-2: -Photoperiodism is the response to changes in daylength that enables plants to adapt to seasonal changes in their environment. The best studied example of photoperiodism in plants is flowering, but other responses to daylength include bud dormancy and bulb or tuber initiation.
Detailed explanation-3: -The relative length of day and night is known as photoperiod. Some plants need to be exposed to sunlight for a particular duration of time to induce flowering. This is the reason behind the seasonal blooming of flowers.
Detailed explanation-4: -Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower-switch to reproductive mode-only at certain times of the year.
