The Photoperiod: Handling and Causing Stress in Plants

Frontiers in Plant Science, 2022
The photoperiod, which is the length of the light period in the diurnal cycle of 24 h, is an important environmental signal. Plants have evolved sensitive mechanisms to measure the length of the photoperiod.

Plants Distinguish Different Photoperiods to Independently Regulate Post-Flowering Vegetative Growth and Reproductive Growth [PDF]

Plants
The post-flowering stage is critical for plant yield and seed quality. This can be influenced by the photoperiod; however, the underlying mechanisms are not clear.

Shining a Light on Patterns of Photoperiod Sensitivity in Germination and Flowering Across Latitudes, Ecosystems and Functional Traits [PDF]

Ecology and Evolution
In photoperiod sensitive plants, the timing of phenological events depends primarily on day length rather than temperature, precipitation or other environmental variables.

Identification of photoperiod as a regulator of dopamine-mediated behavior in female mice [PDF]

Neurobiology of Sleep and Circadian Rhythms
Photoperiod is the primary environmental cue that regulates changes in behavior across seasons. Previously, we have shown that photoperiod has sex-specific effects on synaptic dopamine dynamics in the nucleus accumbens (NAc).

Extended photoperiod improves growth and nutritional quality of pak choi under constant daily light integral [PDF]

Frontiers in Plant Science
Introduction and AimThe duration of light exposure each day, termed the photoperiod, is a crucial environmental cue that influence several aspects of plant physiology, including growth, development, and metabolic activity.

Photoperiod Stress in Arabidopsis thaliana Induces a Transcriptional Response Resembling That of Pathogen Infection

Frontiers in Plant Science, 2022
Plants are exposed to regular diurnal rhythms of light and dark. Changes in the photoperiod by the prolongation of the light period cause photoperiod stress in short day-adapted Arabidopsis thaliana.

Photoperiod effects in a freshwater community: Amphibian larvae develop faster and zooplankton abundance increases under an early‐season photoperiod

Ecology and Evolution, 2023
Organisms that shift their phenologies in response to global warming will experience novel photic environments, as photoperiod (daylength) continues to follow the same annual cycle.

Photoperiod Insensitivity in Pigeonpea Introgression Lines Derived from Wild Cajanus Species

Agronomy, 2022
Pigeonpea is a photoperiod-sensitive crop; therefore, the introgression of photoperiod insensitivity could increase its adaptability to new environments.

Effects of Different Photoperiods on the Growth and Nutritional Characteristics of Two Celery Cultivars in Plant Factory

Agronomy, 2023
Three different photoperiod treatments (8 h/16 h, 12 h/12 h, and 16 h/8 h of light/dark) were implemented to investigate the impact of growth, biomass, and phytochemical accumulation in two celery cultivars, namely ‘Zhangqiubaoqin’ (BQ) and ...
