photoperiodic induction
Content of Hydroxycinnamic Acids and Free Auxins in Tobaccos during Photoperiodic Induction
      
rubrum plants was considered, particularly, the possibility of melatonin (N-acetyl-5-methoxytryptamin) participation in photoperiodic induction.
      
Using a direct amplification of genomic DNA from two Brassica rapa forms, we obtained two homologs of the CONSTANS gene, which controls the photoperiodic induction of flowering in Arabidopsis plants.
      
The first half of the larval development period was the most sensitive phase for photoperiodic induction.
      
Photoperiodic induction and inheritance of diapause in Pionea forficalis (Lepidoptera: Pyralidae)
      
Photoperiodic induction of diapause in the squash bug, Anasa tristis
      
Treatment of larvae also interfered with the photoperiodic induction of diapause.
      
Photoperiodic induction of reproductive diapause at 18°C was investigated in fourOrius [Heteroptera: Anthocoridae] species.Orius insidiosus (Say) displayed a long-day response with a critical photoperiod between L11:D13 and L12:D12.
      
Photoperiodic induction of larval diapause and temperature-dependent termination in a wild multivoltine bruchid,Kytorhinus sharp
      
Tidal influences on the photoperiodic induction of tetrasporogenesis in Bonnemaisonia hamifera (Rhodophyta)
      
Photoperiodic induction was affected by tides, principally by the time of day at which high and low water occurred through the spring/neap cycle.
      
1.The pupal eclosion rhythm imSarcophaga argyrostoma was compared with the photoperiodic induction of diapause in the same species.
      
An experimental and theoretical analysis of photoperiodic induction in the flesh-Fly,Sarcophaga argyrostoma
      
1.Photoperiodic induction of diapause inNasonia vitripennis andSarcophaga argyrostoma was shown to be different in a number of respects.
      
The ratek also remained close to zero when quail were exposed to 3 h photoperiods in cycles between 21 and 36 h in length, and underT30 the critical daylength for photoperiodic induction was only 1.5 h shorter than that underT24.
      
We interpret the results of these experiments as evidence for photoperiodic induction of secretion of maturation-inducing factor (MH) by the brain in the absence of the gonad.
      
Photoperiodic induction of the first and the second diapause in the bean bug, Riptortus clavatus: a photoperiodic history effect
      
Therefore, the photoperiod which had induced the first diapause affected the photoperiodic induction of the second diapause not only in the critical daylength but also in the speed of response.
      
The light sensitivity threshold for photoperiodic induction of diapause was found to be extremely low, viz.
      
Over this period circulating levels of LH increased seven-fold, indicating that photoperiodic induction had taken place in the birds.
