LED lighting as a solution for turf shading: insights from a systemic assessment of

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
Introduction: The roof structures of professional enclosed stadiums often cause shading problems on the turf, posing a major challenge to maintaining turf quality and efficient management. Artificial lighting has been applied to address this issue, particularly light-emitting diode (LED). Methods: To evaluate the efficacy of LED with a specific wavelength in alleviating the adverse effects of shade stress on turfgrasses, we conducted a systematic and multi-dimensional assessment of Results: The results demonstrated that LED effectively alleviated shade-induced light limitation. It maintained turf normalized difference vegetation index (NDVI) and chlorophyll content at levels comparable to those under natural light. Furthermore, LED treatment improved physiological responses associated with shade stress, as indicated by enhanced cell membrane stability, reduced membrane lipid peroxidation, and altered antioxidant-related responses, including increased superoxide dismutase (SOD) activity and dynamic changes in peroxidase (POD) activity. Regarding root morphology, LED treatment reduced the shade-induced increases in specific root length (SRL) and specific root surface area (SRA), suggesting a modification of shade-induced root morphological responses. Principal component analysis (PCA) revealed distinct multivariate response patterns associated with different light environments. Correlation analysis further indicated significant associations among NDVI, chlorophyll content, and antioxidant-related traits across different light environments. These associations suggested that turf performance under LED lighting was related to concurrent variation in chlorophyll content and antioxidant-related traits. Discussion: In conclusion, applying LED lighting can effectively improve turf recovery-related traits and physiological status through improvements in canopy characteristics, chlorophyll status, antioxidant-related responses, and root morphological traits. This study demonstrated under a real stadium environment that specific LED lighting can serve as an effective supplemental light source for improving turf performance in shaded areas, providing practical guidance for stadium turf management.
