Title The Safe Distance Between Road Lighting Fixtures and Street Trees. Type Journal Article
Year 2019 Publication Journal of Landscape Research Abbreviated Journal
Volume 11 Issue 2 Pages 41-43
Keywords Plants; Planning
Abstract (up) The road lighting system and the road greening system, which are mutually interrelated and independent, are two important parts in the urban road environment Unreasonable road lighting is easy to induce light pollution and has a great negative impact on the physiology and growth of garden plants in the urban green space. In this paper; 21 kinds of common tree species in the urban green space of Zhengzhou were selected as the research object, and the photosynthetic physiological parameters of landscape trees under the TKD light source were observed using LI-6400 Photosynthesis System. This paper attempted to find the critical point for initiating photosynthesis of different types of tree species under a certain light source and then calculated the safe distance between lighting fixtures and landscape trees. The results showed that road lighting interfered with the photosynthetic physiological activities of the surveyed trees, affecting the normal dormancy of the plants at night; the sensitivity of different tree species to night lighting was different, and there were some differences in the light compensation points, so the corresponding safe distance was also different It is hoped that this study can provide a valuable reference and scientific basis for urban toad greening and lighting design.

Title Impacts of Artificial Light at Night on Biological Timings Type Journal Article
Year 2017 Publication Annual Review of Ecology, Evolution, and Systematics Abbreviated Journal Annu. Rev. Ecol. Evol. Syst.
Volume 48 Issue 1 Pages 49-68
Keywords Animals; Plants; Review
Abstract (up) The use of artificial lighting to illuminate the night has provided substantial benefits to humankind. It has also disrupted natural daily, seasonal, and lunar light cycles as experienced by a diversity of organisms, and hence it has also altered cues for the timings of many biological activities. Here we review the evidence for impacts of artificial nighttime lighting on these timings. Although the examples are scattered, concerning a wide variety of species and environments, the breadth of such impacts is compelling. Indeed, it seems reasonable to conclude that the vast majority of impacts of artificial nighttime lighting stem from effects on biological timings. This adds support to arguments that artificial nighttime lighting has a quite pervasive and marked impact on ecological systems, that the rapid expansion in the global extent of both direct illuminance and skyglow is thus of significant concern, and that a widespread implementation of mitigation measures is required.

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 83-94
Keywords Plants; Lighting
Abstract (up) 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.

Title What Has Been Thought and Taught on the Lunar Influence on Plants in Agriculture? Perspective from Physics and Biology Type Journal Article
Year 2020 Publication Agronomy Abbreviated Journal Agronomy
Volume 10 Issue 7 Pages 955
Keywords Moonlight; Plants
Abstract (up) This paper reviews the beliefs which drive some agricultural sectors to consider the lunar influence as either a stress or a beneficial factor when it comes to organizing their tasks. To address the link between lunar phases and agriculture from a scientific perspective, we conducted a review of textbooks and monographs used to teach agronomy, botany, horticulture and plant physiology; we also consider the physics that address the effects of the Moon on our planet. Finally, we review the scientific literature on plant development, specifically searching for any direct or indirect reference to the influence of the Moon on plant physiology. We found that there is no reliable, science-based evidence for any relationship between lunar phases and plant physiology in any plant–science related textbooks or peer-reviewed journal articles justifying agricultural practices conditioned by the Moon. Nor does evidence from the field of physics support a causal relationship between lunar forces and plant responses. Therefore, popular agricultural practices that are tied to lunar phases have no scientific backing. We strongly encourage teachers involved in plant sciences education to objectively address pseudo-scientific ideas and promote critical thinking.

Title Redesigning the exterior lighting as part of the urban landscape: The role of transgenic bioluminescent plants in mediterranean urban and suburban lighting environments Type Journal Article
Year 2020 Publication Journal of Cleaner Production Abbreviated Journal Journal of Cleaner Production
Volume 242 Issue Pages 118477
Keywords Plants; Lighting
Abstract (up) This research discusses the feasibility of replacing or supporting artificial lighting with Transgenic Bioluminescent Plants (TBP), as a means of minimizing light pollution, reducing electrical energy consumption and de-carbonizing urban and suburban outdoor environments, creating sustainable conditions and enriching the quality of life. Until now, no information is given about the light output of any TBPs and the question “Are the TBPs capable of producing the necessary lighting levels for exterior lighting?” is unanswered. For this reason, a new methodology is proposed for selecting and analyzing the lighting output potential of transgenic plants ted for specific climatic conditions. This methodology considers growth and reduction factors, as well as a formulae for estimating the plants’ luminous output by performing light measurements. Results show that transgenic plants in medium growth can emit a median luminous flux of up to 57 lm, a value that can definitely support low lighting requirements when used in large numbers of plants. From the lighting measurements and calculations performed in this research, the light output of the TBPs for a typical road with 5m width was found equal to 2lx. The amount of plants required was 40 at each side of the road for every 30m of streets with P6 road class. The results show that the use of bioluminescent plants can actually contribute to the reduction of energy consumption, concerning only the lighting criterium, thus creating an enormous opportunity for a new state-of- the-art market and research that could potentially minimize CO2 emissions and light pollution, improve urban and suburban microclimate, mitigate the effects of climate change, as well as provide an alternative means of lighting affecting both outdoor lighting design and landscape planning in suburban and urban settings. Moreover, further research should be applied considering also other possible ecological impacts before applying TBPs for exterior lighting applications.
