“…Terfa et al (2013) also observed in their study that the area of rose leaves grown under white light with 20% BL was much smaller than the area of rose leaves grown under 5% BL. There were similar findings in the study by Ouzounis et al (2014), where the largest leaf area was observed in the rose plants in the combinations 20%B/80%R and 100%R, as compared with the combination 40%B/60%R. Dougher and Bugbee (2001) defined long-term B light doseresponse curves for leaf area in soybean and lettuce.…”

“…It is not only the existence of blue light in the spectrum but also the amount of blue light that matters. In the study by Ouzounis et al (2014) an increased blue light ratio resulted in lower heights of roses and chrysanthemums. Also, in the study by Samuolienė et al (2011) the hypocotyl was much shorter when plants were grown under red light with 10% blue light than in the combination with 5% blue light.…”

The supplementation of blue light to red light enhanced plant growth compared with the use of red alone. The aim of the study was to determine the effect of different doses of blue light on the biometric traits and photosynthesis of dill plants. The plants were grown in pots in a growth chamber. They were grown in red light (100 μmol m -2 s -1 ) and blue light (from 10 to 50 μmol m -2 s -1 ) in five combinations. Light emitting diode modules were the source of light. The plants were evaluated every 7 days during vegetation, for the first time -seven days after germination and later on the 14 th , 21st and 28 th day after germination. The share of blue light in the spectrum significantly influenced the biometric traits of the dill plants. It significantly inhibited the elongation growth of the plants and negatively affected the increase in fresh weight. A small dose of blue light (20%) had positive effect on the plants' area. The research did not reveal a simple relationship between the amount of blue light and dry weight yield. The value of physiological indexes depended both on the combination and measurement time. The plants from the combination with 30% blue light were characterised by the greatest photosynthesis intensity. An effective share of blue light in the spectrum may range from 10 to 30% in relation to red light and depends on the plant's development phase and on the result we want to achieve in the cultivation of plants.

“…Compared with monochromatic blue light or mixtures of red and blue light, the gs in cucumber leaves under red light decreased significantly (Savvides and Fanourakis, 2012). The gs of Rosa hybrida, Chrysanthemum morifolium and Campanula portenschlagiana plants increased with increments of the blue to red light ratio (Ouzounis et al, 2014). Several studies have shown that gs of plants grown (Wang et al, 2009;O'Carrigan et al, 2014;Wang et al, 2015).…”

Light quality can influence the photosynthetic characteristics, morphology and physiological processes of plants. To investigate the effects of different light qualities (white light, W; red light, R; blue light, B; mixture of red and blue light, RB) of light emitting diodes (LEDs) and white cold fluorescent lamp on the growth and morphology of fruiting mulberry plants (Morus alba L. cv. 'Longsang No.1'), fruiting mulberry plants were grown under different light qualities: W, R, B and RB of the same photosynthetic photo flux density (PPFD; 100 μmol m -2 s -1 ) for 20 d. Our results showed that stem length and leaf area of plants grown under R were the highest. However, stem length and leaf area of plants grown under B were lowest. Dry weights (DW), leaf mass per area (LMA), chlorophyll a/b ratio, soluble protein content, sucrose and starch content, and total leaf nitrogen (N) content of plants grown under R were the lowest. Net photosynthetic rate (Pn), stomatal conductance (gs), and actual photochemical efficiency of PSII (ΦPSII) of plants grown under RB were similar to plants grown under W. Net photosynthetic rate (Pn) and ΦPSII of plants grown under R and B were lower than plants grown under W and RB. Antioxidant enzymes activity of plants grown under R, RB and B were higher than plants grown under W. The number of leaf stomata, leaf thickness, palisade tissue length and spongy tissue length were the lowest in plants grown under R. The number of leaf stomata, leaf thickness and palisade tissue length of plants grown under RB and B were higher than plants grown under R. The results of this study indicate that a certain ratio of mixed red and blue LEDs light can reduce adverse effects of monochromatic red and blue LEDs light on fruiting mulberry growth and development.

“…Hernández and Kubota (2015) measured a 20% increase in Pnet in cucumber as blue light fraction increased from 10 to 80%. Ouzounis et al (2014) and Ouzounis et al (2015) reported, however, that there was no effect of blue light fraction on photosynthesis in roses, chrysanthemums and campanulas and lettuce. The results of these studies are in contrast to the spectral efficiency curves of Hoover (1937), McCree (1972) and Inada (1976), which indicate the blue light is used less efficiently in photosynthesis.…”
