Answer :
The developmental response to relative lengths of light and dark periods is known as Photoperiodism.
Photoperiodism is the physiological response of an organism to the length of night, or periods of darkness. It is found in plants and animals. Plant photoperiodism can also be defined as the developmental response of plants to the relative lengths of light and dark periods.
Photoperiodism is the response to changes in day length that allows 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.
