GlossaryPhotoperiod

length of daily light exposure affecting biological processes

Photoperiod refers to the length of time each day that an organism is exposed to daylight. This period of light exposure can significantly influence biological processes such as flowering in plants, breeding cycles in animals, and even hair growth patterns in humans. Understanding photoperiod is crucial for professionals in fields like agriculture, biology, and medicine, as it helps in optimizing growth conditions and managing seasonal behaviors.
