41 p, 838.7 KB Correction of PRI for carotenoid pigment pools improves photosynthesis estimation across different irradiance and temperature conditions / Kováč, Daniel (Global Change Research Institute CAS) ; Veselá, Barbora (Czech Academy of Sciences. Global Change Research Institute) ; Klem, Karel (Czech Academy of Sciences. Global Change Research Institute) ; Večeřová, Kristýna (Global Change Research Institute CAS) ; Materová Kmeco, Zuzana (Ostrava University) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Urban, Otmar (Global Change Research Institute CAS)
We studied the influence of changing carotenoid pigments on the sensitivity of the photochemical reflectance index (PRI) to photosynthesis dynamics. The goal of the measurements was to examine how the introduction of ΔPRI into the working dataset can improve the estimation of photosynthesis. [...]

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. [...]

The present work has explored for the first time acclimation of upper versus lower canopy leaves along an altitudinal gradient. We tested the hypothesis that restrictive climatic conditions associated with high altitudes reduce within-canopy variations of leaf traits. [...]

Servei de Ressonància Magnètica Nuclear) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Shoots and roots are autotrophic and heterotrophic organs of plants with different physiological functions. Do they have different metabolomes? Do their metabolisms respond differently to environmental changes such as drought? We used metabolomics and elemental analyses to answer these questions. [...]
