“…The use of artificial lighting at night (night interruption, NI) can regulate the flowering of photoperiodic species [ 13 , 14 ]. The NI breaks a long dark period to deliver photoperiodic lighting and thereby create modified long day (LD) conditions [ 15 ]. It has been reported that Cymbidium aloifolium photosynthesizes during 4 h NIs of photon fluence as low as 3–5 μmol·m −2 ·s −1 suggesting that the increased growth and earlier flowering times that occur in response to NI be attributed to an increase in net photosynthesis during this NI period [ 16 ].…”

The impact of shifts in the spectral quality of light on morphogenesis, flowering, and photoperiodic gene expression during exposure to light quality of night interruption (NI) was investigated in Dendranthema grandiflorum. The circadian rhythms of plants grown in a closed walk-in growth chamber were interrupted at night for a total of 4 h, using light-emitting diodes with an intensity of 10 μmol·m−2·s−1 PPF. The light quality of the NI was shifted from one wavelength to another after the first 2 h. Light treatments consisting of all possible pairings of blue (B), red (R), far-red (Fr), and white (W) light were tested. Plants in the NI treatment groups exposed to Fr light grew larger than plants in other treatment groups. Of plants in NI treatment groups, those in the NI-WB treatment grew the least. In addition, the impact of shifts in the light quality of NI on leaf expansion was greater in treatment groups exposed to a combination of either B and R or R and W light, regardless of their order of supply. Flowering was observed in the NI-RB, NI-FrR, NI-BFr, NI-FrB, NI-WB, NI-FrW, NI-WFr, NI-WR, and SD (short-day) treatments, and was especially promoted in the NI-BFr and NI-FrB treatments. In a combined shift treatment of B and R or B and W light, the NI concluded with B light (NI-RB and NI-WB) treatment induced flowering. The transcriptional factors phyA, cry1 and FTL (FLOWERING LOCUS T) were positively affected, while phyB and AFT were negatively affected. In conclusion, morphogenesis, flowering, and transcriptional factors were all significantly affected either positively or negatively by shifts in the light quality of NI. The light quality of the first 2 h of NI affected neither morphogenesis nor flowering, while the light quality of the last 2 h of NI significantly affected both morphogenesis and flowering.

“…in economic applications (Vince-Prue and Canham, 1983), the ecological meaning of day-length controlled phenomena have received much less attention. Physiological research itself contributed little to these fields (but see Cumming, 1961), as the unsystematic and delimited spectrum of experimental plants exhibits almost no relationship to the fields of systematics, ecology or geography.…”

“…By over-or down-expressing light receptors, it is possible to modify some characters specifically regulated by phytochromes, such as plant development, circadian rhythms, apical dominance, blossom, growth and fruit ripening, photosynthesis products partitioning, development of photosynthetic systems, transpiration control and hormone synthesis (Vince-Prue and Canham 1983;Tucker 1976;Muleo and Thomas 1993;Muleo and Thomas 1997). Several phytochromes are present in the plants, e.g.…”
