    Influence of the chlorophylls-to-carotenoids ratio on light use efficiency estimation by optical parameters

  • Original language description

    The influence is examined of changing leaf photosynthetic pigments concentrations on sensitivity of thenphotochemical reflectance index (PRI) and ΔPRI optical parameters in relation to light use efficiencyn(LUE). Photosynthetic and leaf chlorophylls-to-carotenoids (Chl/Car) ratio changes during the growth ofnEuropean Beech (Fagus sylvatica) and Norway spruce (Picea abies) saplings were induced by altering thenliving environment inside growth chambers. Point reflectance measurements of each individual tree werenrecording changes in optical properties while measurements were being taken simultaneously of alteringnphotosynthesis. Based on the evaluation of 45 pairs of measurements conducted on six individual saplings,nthe observed variability in the strength of the PRI and ΔPRI versus LUE relationships was compared to thenresulting leaf Chl/Car ratio of each tree. Data were used to explain the influence of changing pigments onnthe sensitivity of each individual optical parameter with regards to the LUE estimation.
