The Photoperiod: Handling and Causing Stress in Plants [PDF]
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 [PDF]
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.

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

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.

Prediction of Flowering Occurrence in Faba Bean (Vicia faba L.)
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2011 This study is about quantifying response flowering rate to temperature and photoperiod. Results indicated that the response of faba bean flowering rate is described by beta-segmented ( Barekat , Saraziri , Eraghi ) and beta-quadratic functions ( Gavi ).
