  Title Effect of Supplemental Light on the Quality of Green Asparagus Spears in Winter ‘Fusekomi’ Forcing Culture Type Journal Article
  Year 2016 Publication Environment Control in Biology Abbreviated Journal Environmental Control in Biology  
  Volume 54 Issue 3 Pages (down) 147-152  
  Keywords Plants  
  Abstract Winter ‘fusekomi’ forcing culture of asparagus is becoming popular in Japan because the method can make production of asparagus possible during cold season. However, there are some problems such as color of the spear is pale, and rutin content is lower compared to spring harvest due to the low light intensity, especially in the production area which has much snow and short sunshine. The objective of this study was to clarify the effect of supplemental lighting on the yield, rutin content, sugar component (fructose, glucose, sucrose), and the color of spears. The experiments were conducted by using different irradiation time and different numbers of fluorescent lamps hanging on the tunnel poles over the cultivation bed on the winter ‘fusekomi’ forcing culture. Compared to the control, rutin content was significantly increased under supplemental lighting plots. No significant difference or negative impact was observed in sugar contents and yield on each plot. Moreover, spear color also appeared to be better under supplemental lighting than that of the control. These results suggested that supplemental lighting was effective to improve the quality of asparagus spears (such as rutin contents, spears color), especially for the production area that has low light intensity or in short day conditions.

  Title Quantified effects of artificial versus natural nighttime lighting on the Eurasian grassesBothriochloa bladhii(Poaceae) andBothriochloa ischaemum(Poaceae) and the North American grassesPanicum virgatum(Poaceae) andSorghastrum nutans(Poaceae) Type Journal Article

  Abstract Artificial nighttime lighting (light pollution) is increasing worldwide and may have undocumented consequences. In this study, we asked if artificial nighttime lighting affects the performance in monoculture of four grass species: the Eurasian Bothriochloa bladhii (Retz.) S.T. Blake (Poaceae), and Bothriochloa ischaemum (L.) Keng (Poaceae); and the North American Panicum virgatum (L.) (Poaceae), and Sorghastrum nutans (L.) Nash (Poaceae). We conducted a field pot experiment to test for the effects of artificial nighttime lighting and plant density on height, biomass, and leaf number. Height of the tallest individual per population was affected by separate interactions between species and density, light, and time. Final total biomass per individual biomass was increased under nighttime lighting, but more so at low density. Leaf number was increased by artificial nighttime lighting irrespective of species. These results suggest that artificial nighttime lighting may have previously undocumented influences on plant height, biomass, and leaf number within certain species. These findings warrant more in-depth studies into the role that artificial nighttime lighting can have on various plant species.

  Title Keeping the rhythm: light/dark cycles during postharvest storage preserve the tissue integrity and nutritional content of leafy plants Type Journal Article
  Year 2015 Publication BMC Plant Biology Abbreviated Journal BMC Plant Biol  
  Volume 15 Issue Pages (down) 92  
  Keywords Plants  
  Abstract BACKGROUND: The modular body structure of plants enables detached plant organs, such as postharvest fruits and vegetables, to maintain active responsiveness to environmental stimuli, including daily cycles of light and darkness. Twenty-four hour light/darkness cycles entrain plant circadian clock rhythms, which provide advantage to plants. Here, we tested whether green leafy vegetables gain longevity advantage by being stored under light/dark cycles designed to maintain biological rhythms. RESULTS: Light/dark cycles during postharvest storage improved several aspects of plant tissue performance comparable to that provided by refrigeration. Tissue integrity, green coloration, and chlorophyll content were generally enhanced by cycling of light and darkness compared to constant light or darkness during storage. In addition, the levels of the phytonutrient glucosinolates in kale and cabbage remained at higher levels over time when the leaf tissue was stored under light/dark cycles. CONCLUSIONS: Maintenance of the daily cycling of light and dark periods during postharvest storage may slow the decline of plant tissues, such as green leafy vegetables, improving not only appearance but also the health value of the crops through the maintenance of chlorophyll and phytochemical content after harvest.

  Title Urban park lighting as a source of botanical light pollution Type Journal Article
  Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL  
  Volume 11 Issue 3 Pages (down) 90  
  Keywords Plants  
  Abstract That paper describesthe relative impact of anartificial lighting deviceon botanical light pollution, consideringspectral power distribution (SPD in the lighting area. This impact is described by the Relative-to-Moon Photosynthesis Index (RMPI)and Induced Phytochrome Index (IPr). We found that in the case when lighting is realized by using LED luminaires instead of high-pressure sodium (HPS) or metal halide (MH) lamps, the influence of spectral light on plant vegetation process amplifies. Additionally,our research shows that estimating botanical light pollution on the basis of lamps’CCT is not the best method and that using SPD is better for this purpose.

  Title Advanced lighting technology in controlled environment agriculture Type Journal Article
  Year 2016 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology  
  Volume 48 Issue 1 Pages (down) 83-94  
  Keywords Plants; Lighting  
  Abstract There is a recent awareness of the importance of plants in our everyday lives. Light is a requirement for plants and serves two important roles. It provides energy for growth and provides information that elicits plant responses including, among others, plant shape, pigmentation, nutritional content and resistance to stress. Light is paradoxical to plants, it is a requirement however, in excess it is damaging. Plants sense and interpret light through many families of photoreceptors and through the energy state of the photosynthetic apparatus. Light emitting diodes (LEDs) are quickly replacing traditional light sources for human applications, and currently there is effort being put into tailoring these technology platforms for the plant community. Potential plant sensing pathways and the spectral effects on pigmentation and photochemistry in red lettuce are described.
