  Title Roadway Lighting’s Impact on Altering Soybean Growth – Volume 2: LED versus HPS Color Spectral Impact Type Journal Article
  Year 2018 Publication Technical Report Abbreviated Journal  
  Volume (down) FHWA-ICT-18-009 Issue Pages  
  Keywords Plants  
  Abstract The impact of roadway lighting on soybean plant growth and development, was measured in situ at three locations in the state of Illinois. These locations were situated in close proximity of each other for the purpose of evaluating whether there was a difference in the soy response to HPS roadway lighting, versus soy lit by a specific model of 4,000K LED roadway lighting. The plant data collection included the reproductive-stage, the plant moisture content, and the dried seed weight after harvest. The impact of the type of roadway lighting on the reproduction stage and normalized yield was within the modeling confidence limits at a level of 90%. Modifications are recommended to the specification for roadway lighting trespass. This will minimize the impact on soybean plants based on the two roadway luminaire designs included in this study.

  Title The efficiency of different light sources in inducing spray carnation flowering Type Journal Article
  Year 1982 Publication Scientia Horticulturae Abbreviated Journal  
  Volume (down) 18 Issue Pages 159--167  
  Keywords Plants  
  Abstract Light from Gro-lux fluorescent lamps, as a 4-h night break, was found to be more effective than incandescent light in promoting spray carnation flowering under natural daylight conditions. When the illuminations were applied for 4 h in the middle of the night, the effectiveness of a certain amount of radiant energy from incandescent light was found to be the same whether applied as intermittent or as continuous illumination.

  Title Roadway lighting's impact on altering soybean growth: Volume 1 Type Journal Article
  Year 2017 Publication Illinois Center for Transportation Abbreviated Journal  
  Volume (down) Research Report No. FHWA - ICT - 17 - 010 Issue Pages  
  Keywords plants; Lighting  
  Abstract The impact of roadway lighting on soybean plant growth and development was measured in situ at seven locations in the state of Illinois. The plant data collection included periodic height, reproductive stage, and Normalized Difference Vegetation Index (NDVI), as well as plant moisture content and dried seed weight after harvest. The periodic measurements were made at the same locations over time to determine delays in plant development. The impact of roadway lighting trespass was significant and measurable above thresholds of both horizontal and vertical illuminance as well as a combination of the two. A specification was drafted to minimize the impact of roadway lighting trespass on the soybean, and countermeasures were recommended to control the impact of lighting on the soybean.

  Title Interaction of photoperiod and temperature in flowering-control of Gypsophila paniculata L Type Journal Article
  Year 1982 Publication Scientia Horticulturae Abbreviated Journal  
  Volume (down) 16 Issue 4 Pages 385-393  
  Keywords Plants  
  Abstract Long day promotes flowering of Gysophila paniculata L cultivar ‘Bristol Fairy’. Repeated treatments with GA3 or GA4 + 7 in short days did not promote flowering. The long photoperiod is effective only at relatively high temperatures. At night temperatures below 12°C, the plants remain vegetative even in long days. Efficient artificial lighting is from incandescent lamps at 60–100 lux. Fluorescent lighting (Cool-White) is not effective. Lighting of 4 hours as a night-break or at the end of the night were equally effective, but 4 hours lighting as a day-extension was less effective. Whole-night lighting promoted flowering more than any of the 4-hour lighting regimes. Cyclic lighting of one third light in each cycle promoted flowering to the same extent as continuous lighting. Light intensity during the day has a decisive effect on flower production.

  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 (down) 15 Issue Pages 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.
