Estimation of photosynthetic dynamics in forests from daily measured fluorescence and PRI data with adjustment for canopy shadow fraction / Kováč, Daniel (Czech Academy of Sciences. Global Change Research Institute) ; Novotný, Jan (Czech Academy of Sciences. Global Change Research Institute) ; Šigut, Ladislav (Czech Academy of Sciences. Global Change Research Institute) ; Ač, Alexander (Czech Academy of Sciences. Global Change Research Institute) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Grace, John (University of Edinburgh. School of GeoSciences) ; Urban, Otmar (Czech Academy of Sciences. Global Change Research Institute)
We conducted year-long measurements of the photochemical reflectance index (PRI) and solar-induced fluorescence in the O2A oxygen band (SIFA) at a Norway spruce forest and a European beech forest to study relationships of these remote sensing variables to photosynthesis by trees in grown forest stands.

27 p, 2.9 MB Potential of Photochemical reflectance index for indicating photochemistry and light use efficiency in leaves of European beech and Norway spruce trees / Kováč, Daniel (Global Change Research Institute CAS) ; Veselovská, Petra (Global Change Research Institute CAS) ; Klem, Karel (Global Change Research Institute CAS) ; Večeřová, Kristýna (Global Change Research Institute CAS) ; Ač, Alexander (Global Change Research Institute CAS) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Urban, Otmar (Global Change Research Institute CAS)
Hyperspectral reflectance is becoming more frequently used for measuring the functions and productivity of ecosystems. The purpose of this study was to re-evaluate the potential of the photochemical reflectance index (PRI) for evaluating physiological status of plants. [...]
