“…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). Similarly, the effects of CO 2 on roses have also been well documented (Urban et Interestingly, the combination of supplementary lighting and CO 2 led to improved flower stem production and quality in Alstroemeria compared to supplementary lighting alone (Van Labeke and Dambre 1998).…”

“…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 beneficial effects of supplementary lighting on the cultivation of horticultural crops such as vegetables, fruits, and ornamental plants have been also reported (Fierro et al 1994, Gunnlaugsson andAdalsteinsson 2006;HoviPekkanen and Tahvonen 2008;Pettersen et al 2010).…”

Combined effects of supplementary light and CO₂on rose growth and the production of good quality cut flowers

et al. 2016

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.

“…Meanwhile, the MB treatment with relatively less shading had better light irradiation of the lower canopy in the reproductive stage (Fig. 3), and this improved light environment should lead to an enhancement in fruit yield (Hovi et al, 2004;McAvoy and Janes, 1988;Pettersen et al, 2010;Trouwborst et al, 2010). This hypothesis was confirmed by the significantly higher fruit development speed and both fresh and dry yield observed in MB, compared with F14.3 ( Fig.…”

Responses of Leaf Photosynthesis, Plant Growth and Fruit Production to Periodic Alteration of Plant Density in Winter Produced Single-truss Tomatoes

et al. 2017

Tomato plants in greenhouse production are often confronted with light insufficiency in the lower canopy, especially in the winter low irradiation season. In this study, periodic alteration of plant density (PD) was proposed to improve the light environment of plants' lower canopies, leaf photosynthesis, plant growth, and fruit development. These were investigated with winter cultivated tomatoes in a single-truss production system. Seedlings were transplanted to either movable or fixed cultivation benches for treatments with fixed PDs of 14.3 plants·m at mature green to red-ripe). The leaf photosynthesis rates in MB and F10 were generally significantly higher than in F14.3. F14.3 had the tallest stems, but the lowest leaf area and shoot dry weight at end of experiment, while MB and F10 were not significantly different. MB had significantly the highest total yield, while the lowest data were observed in F10. The soluble solids content was increased in MB and F10 compared with F14.3, but no significant differences in ascorbic acid content or fruit hardness were observed among treatments. Therefore, a high PD in the vegetative stage, but a relatively lower PD in the fruit development stage, was highly efficient in intensive tomato cultivation.

“…Recently in Northern Europe and Canada, supplemental lighting techniques have been developed for many plants, illuminating them plants from the top or the side by using high-pressure sodium lamps, fluorescent lamps, and light emitting diodes (LEDs) for in tomato (Gosselin et al, 1996;Gunnlaugsson and Adalsteinsson, 2006;Heuvelink et al, 2006), cucumber (Hovi et al, 2004;Hovi-Pekkanen and Tahvonen, 2008;Pettersen et al, 2010;Trouwborst et al, 2010), and sweet pepper production (Hovi-Pekkanen et al, 2006). These countries have insufficient DLI from natural light between the autumn and spring to grow such crops.…”

“…Many studies have shown the positive effects of supplemental lighting on fruit growth and yield (Gosselin et al, 1996;Hovi et al, 2004;Gunnlaugsson and Adalsteinsson, 2006;Hovi-Pekkanen and Tahvonen, 2008;Pettersen et al, 2010). Some of these studies showed the seasonal effect of supplemental lighting, i.e., that increases yields of tomato (Heuvelink et al, 2006) and sweet pepper (Hovi-Pekkanen et al, 2006) throughout the year, except from June to August.…”

We assessed the effects of light intensity (photosynthetic photon flux [PPF in µmol·m -2 ·s -1 ]) and number of irradiated leaves on photosynthesis and the fruit growth of individual tomato plants to develop supplemental LED lighting techniques for greenhouse tomato production. In Experiment (Exp.) 1, three PPF levels (P200, P500, and P1000) were applied to a post-anthesis tomato plant for three weeks, each plant pruned to have one leaf and one truss with three flowers. The fruit set and leaf and fruit dry-weight increased with increasing PPF; however, after P500 and P1000 treatments, the leaves showed signs of stress and accompanying disorders. Thus, to increase the fruit set ratio and growth rate of tomato fruits and plants, the total amount of irradiation received by each plant should be increased by increasing the number of irradiated leaves, rather than raising the PPF per leaf. For prolonged cultivation, P200 was the optimal PPF per leaf under the tested treatments. Exp. 2 used standard tomato plants with no leaves or trusses removed. We used an assimilation chamber to examine the effect of the number of leaves receiving P200 irradiation on the photosynthetic rate (Pn) per plant (above ground part). The Pn per plant in treatments where one and two leaves were irradiated by supplemental LED lighting were, respectively, 12 and 28％ higher than that in the control (only top lighting). Therefore, fruit growth and yields in tomato cultivation may be raised via acceleration of photosynthesis by increasing the number of leaves that receive P200 irradiation rather than by increasing PPF.
