The length of the light period over 24 h, also named photoperiod, regulates many aspects of plant growth. For example, trees stop growing when days shorten in autumn foreseeing the arrival of cold winter. There are more examples of developmental traits regulated by changes in photoperiod, some discussed in this review.

Feb 9, 2024 · 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.
Suppose a plant that flowers throughout the spring opens its flowers every morning. The sun rises earlier in the late spring compared to the early spring (photoperiod increases in late spring). As time passes and the plant detects the changing photoperiod (technically, plants measure the length of the night rather than daylength; see above), the circadian clock would adjust such that its ...
Nov 1, 2006 · Plants that have this self-amplification mechanism of FT transcription could explain observations from classical grafting experiments (e.g. a Perilla crispa leaf that had been treated once with floral inductive photoperiod could continuously induce flowering in multiple grafts; in Xanthium, non-induced leaves from a stock induced to flower by grafting floral-induced leaves could initiate ...

Nov 12, 2008 · Summary. Photoperiod controls many developmental responses in animals, plants and even fungi. The response to photoperiod has evolved because daylength is a reliable indicator of the time of year, enabling developmental events to be scheduled to coincide with particular environmental conditions. Much progress has been made towards understanding ...

Jan 24, 2022 · The interplay between the photoperiod and the circadian clock regulates developmental processes, such as flowering, tuberization, bud setting, dormancy, and senescence, and improves the plants’ tolerance to abiotic and biotic stresses. A sudden prolongation of the photoperiod results in photoperiod stress.

What is photoperiodic response in plants?
Photoperiodism is essential for the maintenance of plant and animal fitness in temperate and arctic climates. Photoperiodism is the ability of plants and animals to use the length of day or night, resulting in modification of their activities (Bradshaw & Holzapfel, 2007; Kubota et al., 2014; Lucas-Reina, Romero, Romero, & Valverde, 2015).
