N2 - The impact of elevated [CO2] (e[CO2]) in on yield, biomass (BM) and chlorophyll fluorescence (ChlF) was analyzed in three genotypes of common beans (Phaseolus vulgaris L.), a key food-security crop. Active- and passive-sensed ChlF traits acquired by the Light-Induced-Fluorescence-Transient (LIFT), Moni-Pulse-Amplitude-Modulation (MoniPAM), and Fluorescence Box (FloX) instruments were compared. Total biomass increased for all genotypes under e[CO2], but their biomass partitioning significantly differed. The highest yielding genotype under e[CO2] also showed the highest photosynthetic activity according to different active-sensed ChlF methods. Furthermore, e[CO2] resulted in earlier senescence, which was detected by either satellite- or FloX-derived Normalized Difference Vegetation Index (NDVI). Moreover, we observed a significant agreement between MoniPAM- and LIFT-measured ChlF data (R2 = 0.89, p = 0.02), as well as between SIF and FloX measurements (R2 = 0.62, p = 0.03).
