Photoperiodism - Wikipedia
Photoperiodism is the physiological reaction of organisms to the length of light or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods.
Photoperiodism – Definition, Meaning, & Importance with Diagram
2023年2月3日 · Photoperiodism is a phenomenon that occurs in living organisms like plants and animals. It is defined as the developmental response to the length of day and night. The relative period of day and night is called photoperiod. While photoperiodism is a common occurrence in plants, animals are also found to respond to light, although differently.
Photoperiodism - an overview | ScienceDirect Topics
Photoperiodism is the ability of plants and animals to measure environmental day length (photoperiod), typically by monitoring night length. This process underlies a biological calendar. Photoperiod is inversely correlated to the nightly duration of melatonin secretion in animals.
Plants distinguish different photoperiods to independently control ...
2024年2月9日 · Daylength, or photoperiod, is a stable indicator of the season, and organisms can measure photoperiods to predict seasonal changes in climate. In plants, flowering and growth are often regulated by photoperiod, and the photoperiodic flowering pathway is well understood.
What Is Photoperiodism? - Explore The Process of Photoperiodism …
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. This type of natural phenomenon was first discovered and identified by Charles Darwin and his son Francis in the year 1880.

Photoperiod - an overview | ScienceDirect Topics
Photoperiod represents a reliable information signal for daily or seasonal changes. Photoperiod trigger physiological and biochemical changes that can increase cold tolerance, often via diapause, but not always (Tauber et al., 1986; Hodkova and Hodek, 2004).
