Genetic dissection of photoperiod response based on GWAS of pre-anthesis phase duration in spring barley [PDF]

, 2014
Heading time is a complex trait, and natural variation in photoperiod responses is a major factor controlling time to heading, adaptation and grain yield.

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.

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.

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 ...

Effects of Seasonal Photoperiod on Growth, Lipid Metabolism, and Antioxidant Response in the Huanghe Carp (Cyprinus carpio haematopterus)

Fishes, 2023
Photoperiod is one of the most important environmental cues for organisms, and it plays a crucial role in regulating feeding, behavior, growth, and metabolism.

Determination of photoperiod-sensitive phase in chickpea (Cicer arietinum L).

Frontiers in Plant Science, 2016
Photoperiod is one of the major environmental factors determining time to flower initiation and first flower appearance in plants. In chickpea, photoperiod sensitivity, expressed as delayed to flower under short days as compared to long days, may change ...

The effect of a 24-hour photoperiod on the survival, growth and swim bladder inflation of pre-flexion yellowfin tuna (Thunnus albacares) larvae [PDF]

, 2011
The effects of two different continuous photoperiod regimes on survival, growth and swim bladder inflation of pre-flexion yellowfin tuna (Thunnus albacares) larvae were investigated. Each photoperiod regime was tested twice with a different larval cohort
