Photoperiodism
The shortening length of day causes deciduous plants to shead their leaves and prepare for winter. Also day length can bring plants into flower and fruit.
It is called photoperiodism
Photoperiodism is a mechanism that plants and animals have that reacts to the length of the night and day. It influences flowering because certain types of flowers will only bloom after long periods of darkness, while others can flower during shorter night time periods. Photoperiodism allows the plant to know what time it should flower.
This response is called, photoperiodism.

The three plant tropisms include geotropism, thigmotropism,hydrotropism and photoperiodism.
Photoperiodism is the response of the plant to daylight and darkness. For short day plants it will bloom in darkness and when darkness exceeds critical night length, for long day plants it will bloom during daylight and when darkness is less than the critical night length.
