Lighting strategies for morphological and physiological characteristics of horticultural crops often focus on the proper daily light integral (DLI); however, a suitable combination of photosynthetic photon flux density (PPFD) and photoperiod at the same ...

Sensitivity of Immature \u3ci\u3eThyanta Calceata\u3c/i\u3e (Hemiptera: Pentatomidae) to Photoperiod as Reflected by Adult Color and Pubescence [PDF]
Dimorphism in color and pubescence of adult Thyanta calceata, in response to 8L:16D and 16L:8D photoperiods, resulted from an accumulation of photoperiod effects on two or more immature stages. More immature stages were receptive to 8L:16D than to 16L:8D

Prediction of Flowering Occurrence in Faba Bean (Vicia faba L.)
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 ).

Phenological Restriction of the Oryza (v3) Model [PDF]
Photoperiod sensitivity affects the rice development cycle and its flowering. Crop simulation models, such as ORYZA (v3), use equations that depend on two main parameters calibrated by the user: sensitivity to photoperiod and minimum optimal photoperiod.

Genetic dissection of photoperiod response based on GWAS of pre-anthesis phase duration in spring barley [PDF]
Heading time is a complex trait, and natural variation in photoperiod responses is a major factor controlling time to heading, adaptation and grain yield.

Mapping QTL associated with photoperiod sensitivity and assessing the importance of QTL×environment interaction for flowering time in maize. [PDF]
An understanding of the genetic determinism of photoperiod response of flowering is a prerequisite for the successful exchange of germplasm across different latitudes.

Seasonal changes in moult, body mass and reproductive condition in siskins Carduelis spinus exposed to daylength regimes simulating different latitudes [PDF]
Birds use change in daylength during the year to time events during their annual cycles. Individual Eurasian siskins Carduelis spinus can breed and winter in widely separated areas in different years.

Attainment of reproductive competence, phase transition, and quantification of juvenility in mutant genetic screens [PDF]
Plant development between seedling emergence and flowering is characterized by a series of successive qualitative phases: (1) a post embryonic photoperiodinsensitive phase, during which plants are insensitive to photoperiod; (2) a photoperiod ...

Neuronal activity regulates neurotransmitter switching in the adult brain following light-induced stress. [PDF]
Neurotransmitter switching in the adult mammalian brain occurs following photoperiod-induced stress, but the mechanism of regulation is unknown. Here, we demonstrate that elevated activity of dopaminergic neurons in the paraventricular nucleus of the ...
