“…In various long-day cut flowers, the effects of light quality on flowering were investigated. Yoshimura et al (2002Yoshimura et al ( , 2006 used films to adjust light quality during the day and R-or FR-rich fluorescent lamps at night to demonstrate that a low R: FR ratio enhances flowering in Matthiola incana. Also, photoperiod may affect reproductive development and flowering, as well as a few other metabolic processes (Singh et al, 2015).…”

This study was carried out in the greenhouse of the Horticulture Department Nursery, College of Agriculture Engineering Sciences, Duhok University, Kurdistan region, Iraq, for the period from 1st Aug 2020 to 1st Mar 2021, to study the effect of five supplemental light (control, natural light, Incandescent 14, Incandescent 18, mixed 14, mixed 18) hours daily and three growing medium (river soil, river soil + 30% local compost, river soil + 60% local compost) on some vegetative growth and flowering of two cultivars of carnation plant. The best results (fewest days) for the number of days from planting to bud emergence, visible flower colour, and anthesis were obtained when the plants were exposed to mixed light colours or incandescent lamps for a 14-hour treatment, Also this treatments were significantly superior in the other characteristics like plant height, flower length and flower diameter compared to the control. Medium with 60% local compost significantly increased all the studied characteristics compared with other mediums. The Ormea (Red) cultivar was significantly superior to the Moonlight cultivar in all studies of characteristics and was early in day numbers for bud emergence, visible flower colour, and anthesis. All second interactions between the investigated factors had a significant influence in all studied characteristics. In addition, the triple interaction between the three factors had a significant impact on all characteristics, including the least days or fewest days to flower anthesis of the Ormea cultivar when planted on medium containing 60% local compost under incandescent 14h, which took 101.80 days compared 176.27 days, with an early reach of 74.47 days for the control. The Moonlight (white) cultivar required the fewest days, 128.93 days, for a medium containing 60% compost under mixed 14h, which needed 123.93 days, compared to the control, which required 195.87 days with an early flowering rate of 71.94 days.

“…For example, a low red:far-red ratio maintained using films that change light quality in daytime and redor far-red-rich fluorescent lamps at night promote flowering in Matthiola incana (Yoshimura et al, 2002(Yoshimura et al, , 2006, and low and high red:far-red ratios promote and retard flowering under long-day conditions in Eustoma grandiflorum (Sato et al, 2009;Yamada et al, 2008aYamada et al, , b, 2009). Far-red alone and a low red:far-red ratio promote flowering under long-day conditions with LEDs in Gypsophila paniculata (Nishidate et al, 2012), and a low red:far-red ratio also promotes flowering in Campanula carpatica (Kristinsen, 1988).…”

Characterization of Flowering-related Genes and Flowering Response in Relation to Blue Light in <i>Gypsophila paniculata</i>

The flowering response to monochromatic light and flowering-related genes underlying this response need to be characterized to efficiently use light-emitting diodes for lighting culture. The flowering response to far-red light has been well studied in long-day cut flowers, but there have been few studies investigating the response to blue light. Flowering and the expression of the G. paniculata homologs of the FLOWERING LOCUS T and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 genes (GpFT, GpSOC1) were not previously promoted in Gypsophila paniculata, an important long-day cut flower, 'Bristol Fairy' under long-day conditions with blue light. In the present study, we found that flowering was promoted in another G. paniculata 'Million Star', under long-day conditions with blue light, suggesting that there is variation in G. paniculata's flowering response to blue light. Therefore, we analyzed the expression of GpFT and GpSOC1 in the 'Million Star'. The expression of GpFT and GpSOC1 was promoted with flowering in 'Million Star' under long-day conditions with blue light in contrast to 'Bristol Fairy'. We next analyzed the G. paniculata homologs (GpFKF1, GpGI) of FLAVIN-BINDING KELCH REPEAT F-BOX 1 and GIGANTEA genes, which participate in the flowering response to blue light. GpFKF1 and GpGI amino acid sequences were well conserved; gene expression showed a diurnal rhythm with different peaks under short-day and long-day conditions, as previously observed in Arabidopsis thaliana. GpFKF1 interacted with GpGI. There were no important differences in GpFKF1 or GpGI amino acid sequences between the two cultivars. Our results suggest that variation in the flowering response to blue light is associated with GpFT and GpSOC1, rather than GpFKF1 and GpGI.

“…Yoshimura et al (2002Yoshimura et al ( , 2006 demonstrated that a low R:FR ratio promotes flowering in Matthiola incana by altering the ratios using films that change light quality in the daytime and R-or FR-rich fluorescent lamps at night. Sato et al (2009) and Yamada et al (2008aYamada et al ( , b, 2009) demonstrated that low and high R:FR ratios promote and retard flowering, respectively, in Eustoma grandiflorum under long-day conditions with some types of artificial light source.…”

A low red (R): far-red (FR) ratio is known to promote flowering of Arabidopsis and several long-day cut flowers, whereas not much information is available on the effects of single light qualities and their combinations on flowering. Therefore, the effects of light quality on the flowering of Gypsophila paniculata were investigated using light-emitting diodes (LEDs) emitting the following lights: FR, R, and blue (B). Flowering and flower budding were observed under long-day conditions with FR, while no flowering was observed under short-day conditions. Promotion of flowering and flower budding was increased under FR supplemented with R compared to FR alone. Although generally R inhibits flowering in long-day plants, a certain intensity of R, for example, the R:FR ratio between 0.23 and 0.71, may be necessary for effective promotion of flowering. In contrast, B supplementation of FR was not effective at the ratio in this study in inducing flowering and flower budding. The quality of cut flowers produced under long-day conditions with LEDs that promoted flowering was not lower than that under incandescent lamps. These results will provide basic knowledge for the development of LED bulbs as a replacement for incandescent bulbs.
