The change in duration of secretion thus serves as a biological signal for the organization of daylength-dependent (photoperiodic) seasonal functions such as reproduction, behavior, coat growth, and camouflage coloring in seasonal animals.WikiMatrix WikiMatrix
The principal weather factors which modified tuber initiation and growth were temperature and radiation: daylength was relatively unimportant.springer springer
The poor production of Tegal ducks compared with that in other studies may have been related to their early onset of lay under the 16 h daylength used in the trial or to a sampling effect.springer springer
In mammals, daylength is registered in the suprachiasmatic nucleus (SCN), which is informed by retinal light-sensitive ganglion cells, which are not involved in vision.WikiMatrix WikiMatrix
Although not the only parameter, the changing length of the photoperiod ('daylength') is the most predictive environmental cue for the seasonal timing of physiology and behavior, most notably for timing of migration, hibernation, and reproduction.WikiMatrix WikiMatrix
Daylength, and thus knowledge of the season of the year, is vital to many animals.WikiMatrix WikiMatrix
It has been shown that the pattern of seasonal occurrence is largely dependant on the timing of the activity period of the adult stage and this is regulated by the combined influences of humidity, temperatures and daylength.springer springer
BANKSIANA, did not respond to daylength.springer springer
As is shown inTable 2, the increased daylength induced a marked long-day response in all varieties: haulm growth was stimulated, the growing period lengthened and both tuber number and weight increased.springer springer
The data also indicate an effect of the date of emergence, in combination with daylength and weather conditions after emergence.springer springer
Light intensity and daylength only slightly influenced sprout growth: temperature and variety were of considerable importance.springer springer
The late varieties responded more strongly to the increased daylength than did the second-early varieties.springer springer
None of the 8 species from latitudes 31‡ to 36‡ became completely dormant in a greenhouse after 5 months exposure to an average daylength of 10 1/2 hours.springer springer
The hypothalamus is responsive to: Light: daylength and photoperiod for regulating circadian and seasonal rhythms Olfactory stimuli, including pheromones Steroids, including gonadal steroids and corticosteroids Neurally transmitted information arising in particular from the heart, enteric nervous system (of the gastrointestinal tract), and the reproductive tract.WikiMatrix WikiMatrix
Twelve German varieties of potato were grown at an altitude of 1900 m in Ceylon under normal daylength (ca. 12 hr.) and under a daylength artificially increased to 18 hr.springer springer
The results based on the 7-week testicular weights indicated that quail did not respond to a phase shift in the light period but responded to an abbreviation of a previously established photoperiod.Quail responded to unnatural daylength even when the actual and relative length of the dark period increased.springer springer
