“…Roberts et al (1993) assumed that supplementary lighting using HPS containing a high R:FR ratio increased the number of axillary shoots per plant, because the influence of the high R:FR ratio on lateral branching had been reported in other plants such as chrysanthemums and tomatoes (Mortensen and Stromme 1987;McMahon et al 1991). Similar to our results, Harada and Komagata (2014) obtained increased numbers of cut flowers over 70 cm long using supplementary lighting, and they assumed that the results indicated the promotion of photosynthesis in assimilation shoots, which was based on the findings observed in a similar cultivation system (Kumazaki et al 2012). Pandy et al (2009) found that plants under CO 2 enrichment exhibited significantly increased leaf area and chlorophyll concentrations compared those grown under ambient CO 2 , resulting in a higher photosynthetic rate per leaf.…”

“…Moreover, it has been applied to improve rose plant growth, bud break, flowering bud development, vase life, flower quality, and yield in the greenhouse (Bredmose 1993;Roberts et al 1993;Fjeld et al 1994;Blom-Zandstra et al 1995;Maas and Bakx 1995;Mortensen and Gislerùd 1999;Harada and Komagata 2014). The similar benefits given by supplementary lighting have been also reported on the cultivation of horticultural crops (Gunnlaugsson and Adalsteinsson 2006;Hovi-Pekkanen and Tahvonen 2008;Pettersen et al 2010).…”

Moreover, continuous flower development may stop under unfavorable light conditions, and the flower bud may abort, resulting in a blind shoot (Horridge and Cockshull 1974;Zieslin and Moe 1985).…”

The effects of supplementary lighting with high-pressure sodium (HSP) lamps alone or in combination with carbon dioxide (CO 2 ) on the growth, yield, and flower stem quality of two rose cultivars ('Loving Heart' and 'Top Grace') were studied. Compared to natural lighting (control), supplementary lighting alone was beneficial for plant growth, and it increased plant height, stem diameter, and the number of axillary shoots. Furthermore, increases in flower stem yield (>70 cm), flower stem diameter, fresh weight, and the number of petals per flower were also observed. The combination of supplementary lighting and CO 2 significantly enhanced all of the studied parameters compared to supplementary lighting alone. Moreover, stomatal density and chlorophyll fluorescence were seemingly affected by either supplementary lighting alone or in combination with CO 2 . This is the first study to examine the beneficial effects of combined supplementary lighting and CO 2 conditions, and the resulting information is essential to rose growers and commercial production.

“…The two best linear and polynomial models for each treatment were validated using actual data. Then the error value is investigated using the Mean Absolute Percentage of Error (MAPE) and Mean Absolute Deviation (MAD) approaches, as shown by Equation ( 6) and Equation (7). The prediction data used in this validation is obtained from the model equation (Ft).…”

“…In addition to LED lamps, fluorescent lamps are commonly used in plant factories. Exposure of fluorescent lamps to the plant for an extended period can increase the productivity of roses in autumn and winter in terms of number, length, weight, and stem size [7]. However, LEDs produce the lowest heat compared to other lamps, which are more suitable for plant needs.…”

In the plant factory, plants carry out the process of photosynthesis using artificial light sources in the form of growth lights instead of sunlight. Each type of lamp will emit light with a different wavelength, so the effect on the photosynthesis process is also different. This study examines the pattern of canopy area expansion on plants in response to the light quality of artificial light in the plant factory. Canopy area of Bok choy (Brassica rapa subsp. Chinensis) plant samples for white LED dan red-blue LED treatments were measured non-destructively every two and three days using the Easy Leaf Area application. The growth data is then modeled using linear and polynomial regression. The results showed that the canopy area of the plant in the plant factory increased with the growth period. The plants exposed to red-blue LED lights grew better than plants exposed to white LED, indicating that red-blue lights supported the photosynthesis process better than white light. The regression results also show that the growth of plants in plant factories with a combination of red-blue LED lights is better in terms of MAPE (Mean Absolute Percentage Error) values. The model validation and prediction are also better using red-blue LED than white LED. Based on prediction using the best regression model, the result shows that red-blue LED as artificial light sources better support plant growth in plant factories than white LED lamps.
