Effect of diffuse fraction on gross primary productivity and light use efficiency in a warm-temperate mixed plantation [PDF]
Frontiers in Plant Science, 2022 Diffuse radiation (If) is one of important variables determining photosynthetic rate and carbon uptake of forest ecosystems. However, the responses of gross primary productivity (GPP) and light use efficiency (LUE) to diffuse fraction (DF) are still ...

Supplemental Light-Emitting Diode Inter-Lighting Increases Tomato Fruit Growth Through Enhanced Photosynthetic Light Use Efficiency and Modulated Root Activity. [PDF]
Front Plant Sci, 2019 We investigated the effect of supplemental LED inter-lighting (80% red, 20% blue; 70 W m−2; light period 04:00–22:00) on the productivity and physiological traits of tomato plants (Flavance F1) grown in an industrial greenhouse with high pressure sodium (

Improved light and temperature responses for light-use-efficiency-based GPP models [PDF]
Biogeosciences, 2013 Gross primary production (GPP) is the process by which carbon enters ecosystems. Models based on the theory of light use efficiency (LUE) have emerged as an efficient method to estimate ecosystem GPP.

Photosynthetic light‐use efficiency of rice leaves under fluctuating incident light [PDF]
Agrosystems, Geosciences & Environment, 2020 The responsiveness of photosynthesis to continuously fluctuating light intensities can provide an estimate of the net assimilation rate (A) and photosynthetic light‐use efficiency (PLUE), which cannot be measured under steady‐state conditions. This study

Quantifying soil moisture impacts on light use efficiency across biomes. [PDF]
New Phytol, 2018 Summary Terrestrial primary productivity and carbon cycle impacts of droughts are commonly quantified using vapour pressure deficit (VPD) data and remotely sensed greenness, without accounting for soil moisture. However, soil moisture limitation is known

Photosynthesis, Light Use Efficiency, and Yield of Reduced-Chlorophyll Soybean Mutants in Field Conditions. [PDF]
Front Plant Sci, 2017 Reducing chlorophyll (chl) content may improve the conversion efficiency of absorbed photosynthetically active radiation into biomass and therefore yield in dense monoculture crops by improving light penetration and distribution within the canopy.

Remote sensing of seasonal light use efficiency in temperate bog ecosystems [PDF]
Scientific Reports, 2017 Despite storing approximately half of the atmosphere’s carbon, estimates of fluxes between wetlands and atmosphere under current and future climates are associated with large uncertainties, and it remains a challenge to determine human impacts on the net
