Exemples d’utilisation de PHOTOPERIOD dans une phrase

• Genetic variations may be triggered by a range of factors, including mutations in the genes responsible for the sensing of environmental cues such as photoperiod (day length) or geomagnetic fields, which birds use for navigation.
• Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions.
• But photosynthesis is not the only plant process driven by light, other processes such as photomorphology and plant photoperiod are extremely important for regulation of vegetative and reproductive growth as well as production of plant secondary metabolites.
• Wilson obliged and completed a master's degree in zoology at WSU under Farner in 1957, where he worked on the effects of photoperiod on the physiology of birds.
• Chrysanthemum was one of the plants used in experiments that led to the definitions of photoperiod and photoperiodism.
• Unlike many other root vegetables domesticated by the indigenous peoples of the Andes (ulluco, oca and mashua), yacón is not photoperiod sensitive and can produce a commercial yield in the subtropics, as well as in mountainous regions.
• Alpine plants go into vegetative dormancy at the end of the growing period, forming perennating buds with the shortening photoperiod.
• Many flowering plants (angiosperms) use a circadian rhythm together with photoreceptor protein, such as phytochrome or cryptochrome, to sense seasonal changes in night length, or photoperiod, which they take as signals to flower.
• They provide an excellent model system for the evolution of hormonal control of photoperiod and seasonal physiological and behavioral changes, sociality, biparental offspring care, and behavioral ecology.
• The branchiopod crustacean Daphnia magna parthenogenetically produces male progeny in response to a combination of three environmental factors, namely a reduced photoperiod in autumn, shortage of food and raised population density.
• The day length promotes 50% development and 50% diapause (the critical photoperiod) as the same for the initiation and termination of not developing in unchilled larvae.
• Under controlled conditions of photoperiod, temperature, and water quality, hardhead catfish display nonrandom oscillations in angular orientation of locomotive activity.
• Overexpression, results in the loss of rhythmic expression of clock controlled genes (CCGs), loss of photoperiod control, and loss of rhythmicity in LHY expression.
• Because PBAN can be produced independently of the moth's photoperiod, the circadian rhythm of pheromone production must be closely associated with PBAN release.
• Beck and James Apple worked on geographical variation and photoperiod effects on voltinism in the European corn borer (Pyrausta nubilalis).
