Re-absorption and scattering of chlorophyll fluorescence in canopies: A revised approach
(Elsevier Science Inc., 2020-09)
The measurement of chlorophyll fluorescence in remote way represents a tool that is becoming increasingly important in relation to the diagnosis of plant health and carbon budget on the planet. However, the detection of ...
Modeling re-absorption of fluorescence from the leaf to the canopy level
(Elsevier Science Inc, 2017-11-07)
Chlorophyll fluorescence is widely used as an indicator of photosynthesis and physiological state of plants. Remote acquisition of fluorescence allows the diagnosis of large field extensions, even from satellite measurements. ...
Canopy active fluorescence spectrum tracks ANPP changes upon irrigation treatments in soybean crop
(Elsevier Science Inc., 2021-09)
Accurate estimation of aerial net primary production (ANPP) using remotely acquired data is one of the main challenges in both environmental monitoring and precision agriculture. Reflectance-based techniques have been ...
Dynamics of sun-induced chlorophyll fluorescence and reflectance to detect stress-induced variations in canopy photosynthesis
(Blackwell Publishing Ltd, 2022)
Chlorophyll fluorescence, photochemical reflective index and normalized difference vegetative index during plant senescence
(Elsevier Gmbh, Urban & Fischer Verlag, 2016-07)
The relationship between the Photochemical Reflectance Index (PRI), Normalized Difference Vegetation Index (NDVI) and chlorophyll fluorescence along senescence was investigated in this work. Reflectance and radiance ...
Stem canker caused by Phomopsis spp. induces changes in polyamine levels and chlorophyll fluorescence parameters in pecan leaves
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021-06)
Pecan plants are attacked by the fungus Phomopsis spp. that causes stem canker, a serious and emerging disease in commercial orchards. Stem canker, which has been reported in several countries, negatively affects tree ...

Photophysics at Unusually High Dye Concentrations
(American Chemical Society, 2019-01)
The study of the interaction of light with systems at high dye concentrations implies a great challenge because several factors, such as emission reabsorption, dye aggregation, and energy trapping, hinder rationalization ...
Affecting factors and recent improvements of the photochemical reflectance index (pri) for remotely sensing foliar, canopy and ecosystemic radiation-use efficiencies
(MDPI AG, 2016-08)
Accurately assessing terrestrial gross primary productivity (GPP) is crucial for characterizing the climate-carbon cycle. Remotely sensing the photochemical reflectance index (PRI) across vegetation functional types and ...
