Light-Emitting Diodes (LEDs) have been considered as a lighting source for plant production in vitro and/or ex vitro conditions from the points of several characteristics including lower electric cost, longer lamp life, or controlled spectral wavelength. Light
quality and intensity significantly affect growth and development of greenhouse roses, and their commercial production has been achieved by supplementary light sources with higher electric consumption such as high-pressure sodium, metal halide, and incandescent lamps applying for day-length elongation during a short day-length condition. However, few researches show that supplementary light quality and intensity provided by LEDs affect the cut rose growth under greenhouse conditions. In this study, effects of supplementary radiation by using red and blue plus red LEDs with lower electric cost compared to the
mentioned light sources on growth and yield of a single-stem rose were mentioned. A single-stem rose (Rosa spp. L., cv. ‘Revue’) was used as a plant material. Single-node cuttings of ‘Revue’ were transplanted in rock-wool cubes, and a complete nutrient solution was periodically irrigated by trickle nozzle during culture period. For 3h after sunset, 'Revue' roses were exposed by different light qualities of red (Treatment R) and blue plus red (Treatment BR, 1:1 in energy ratio) LEDs from 2nd June 2010 to 3rd April, 2011. Sodium lamps of 100 Watt (Treatment Na) and natural light treatments were considered as controls. Light intensity on the culture bed of supplementary blue (peak at 470 nm), red (peak at 630 nm), and blue plus red LEDs was maintained at four levels of 500, 1,000, 1,500, and 3,000 lux in each treatment. First harvest after transplanting was 23th September 2010. Cut flower yield per was represented by average value of five times harvests from 2nd June 2010 to 3rd April, 2011. On day 110 after LEDs exposure, fresh and dry weights per cut flower significantly increased by red and blue plus red light of 1,500 lux light intensity compared to Treatment Na of sodium lamp upplementation and natural light condition. Fresh weight was increased above 20% in Treatment R1500 or BR1500 compared to natural light or Na Treatment. Shoot length was also longer under Treatment R1500 or BR1500 than under Treatment Na, although number of nodes was no significant difference in the treatments (p<0.05). This means that stem growth is induced by node elongation rather than increasing in the number of nodes under the experimental conditions. However, there was no significant difference in average growth of five times during the supplementary period from September to April. The rose yield per increased to 45 % and 49 % under Treatment R1500 and BR1500, respectively, compared to control. Especially, inhibition under Treatment Na even though higher light intensity caused by heat from the lamps because of shorter distance among the plant, light source, and roof on domestic greenhouse structure. Effects of supplementary red and mixture radiation of 1,500 lux light intensity on significant yield increment probably due to decreasing in number of blind branches by the light supplementation.
The study was conducted to investigate effects of light emitting diodes on cut-flower production at freesia. There was not difference of growth by different light source, before flowering period. In flowering period, Green LED was reduced 8 days in 'Yvonne' and 13 days in 'Shiny Gold', respectively. Both of 'Yvonne' and 'Shiny Gold' were good result in growth after flowering at metal halide lamp. But, the number of lateral shoot was least in 'Yvonne' and plant weight was least in 'Shiny Gold' at Green LED than others treatments. New corm and cormlet weight were lowest at glow lamp. Chlorophyll content in 'Yvonne' was highest at glow lamp and those of 'Shiny Gold' was highest at green LED and glow lamp. Amount of photosynthesis in both species were highest at glow lamp. And among the LED treatments, green LED and mixed LED were highest in both species.
