Lignocellulosic biomass in leaves provides structural support to the plant, facilitating water transport, and protecting it from biotic threats and various stress factors. Lignocellulose makes up for most portion of the dry weight in tree species. Previously, subdividing leaf mass per area (LMA) into its components, including lignocellulose, using radiative transfer models has been a challenge. However, a recent recalibration of the PROSPECT model, now known as PROSPECT-PRO, has made this possible. Yet the model applicability needs to be explored for coniferous tree species. Therefore, this study aimed to evaluate the ability of PROSPECT-PRO to retrieve leaf lignocellulose for Norway spruce and Scots pine tree species in Germany and the Netherlands. To achieve this, we conducted hyperspectral measurements of fresh leaves and, utilized the spectral range from 800 to 2400 nm and the selection of optimal spectral bands in model inversion for retrieval of lignocellulose.
